Choosing a Health and Fitness Ecosystem - Part 3 - How Calories Burned is Determined

How Calories Burned is Determined

If you have ever done a side-by-side comparison of 2 devices that can calculate your calories burned, either throughout your day or for an activity, then you noticed that they gave anywhere from slightly to dramatically different results. My favorite example is when I was comparing FitBit Charge HR, Garmin 920xt with HRM strap, and non-HR FitBit Flex. The activity was a 30 minute run on the treadmill at a 10 min pace. My burn with Garmin was about 260 calories. The FitBit Charge was just under 280. The Flex was just over 310. So if I was trying to lose weight, and I was relying just on the Flex, I would have thought I could eat over 50 more calories...which is a super yummy snack. That's not good. However, it's not totally bad either and I will explain why.

The Flaw of Caloric Burn

Despite what all of the fitness sites will tell you, heart tracking for determining calorie burn is flawed in so many ways. For example, heart rate monitors are designed to work in an optimal condition of elevated heart rate for a period of time. So, for people who do strength training, caloric burn result will typically be wrong. I am not going into the full details of this, because it's not relevant for this article, but know that your body is a complex machine and it burns calories different based on how your muscles and cardiovascular system are engaged.

I am not saying to throw out your calorie burn results; but I am saying you need to understand that results are based on usually complex equations that are still flawed, because every person's body burns calories a little bit different from the next.

HRM vs. Non-HRM

I am not trying to pick on FitBit, but they are the easiest to use for this example. We are going to use the FitBit Flex and FitBit Charge HR for this segment. Devices and formulas have advanced very far these days, so non-HRM devices that show calories have dramatically improved over time.

Quick disclaimer: I won't be posting any exact formulas because I am not well-versed in the legal jargon that the various companies have around their proprietary formulas, and since I figured out a bunch of them, I fear posting them would put me in trouble. That said, however, I will post what typically goes into the calculations.

At the very basic fitness tracker level, meaning Non-HRM, it will take into account, your age, height, weight, and steps. Most will use your gender as well. Moving up the list for Non-HRM, some have average caloric burns in addition to the various data I already mentioned. Some will even go as far as to then see your averages and adjust accordingly. However, this gets very inaccurate since it needs heart rate.

So, Heart Rate Monitors. The most basic will take into account your age, weight, and heart rate from the activity. It doesn't care about steps, gender, etc. As you can guess, the more advanced keep adding more variables to get a more accurate picture of caloric expenditure. In addition, devices that have the ability to track heart rate (HR) all day, have different formulas than that of a physical activity. So if you don't workout or overexert yourself, it will use one formula to determine your full day calorie burn. If you also exercise or do some activity that raises your heart rate to a certain level or higher, then it will use a different formula, and then add those 2 values together. The devices know to not count workout time into the overall daily burn, since you would get over-inflated results.

In addition, most of the new HRM's and their fitness device (can be separate or the same device) will watch for patterns and adjust the burns as your fitness improves. For example, if I start running for the first time, and I am a bit overweight, my heart rate is going to be higher, and I am going to see a pretty decent calorie burn from a run. Maybe a couple months later after I have lost some weight and my cardiovascular system has more endurance and is more efficient, I might only be burning a fraction of the calories for the same effort.

What Do I Choose?

Despite the above probably being confusing, the decision on whether or not to get an activity tracker or fitness device that can track heart rate is fairly simple. If you aren't someone who counts calories, doesn't care about calories, or you aren't doing any sort of activity or training that you need heart rate data, then there is no reason to get a device that tracks heart rate. Nice and simple, right?

Summary

\In conclusion, many people who just want a device to help keep them active, track activities, or to claim some work or insurance incentives, do not need a device with heart rate tracking capabilities. However, if you don't fall into those categories, you will probably want one; you might not use it right away, but you will. Up next I will be doing a long series of discussing the good, the bad, and the ugly of the various ecosystems out there.

Choosing a Health and Fitness Ecosystem - Part 2 - Activity Tracker vs Fitness Device

Activity Tracker vs Fitness Device

The health and fitness tech market is growing exponentially, with everyone either wanting to get healthy or being obsessed with numbers. However, before you jump on the bandwagon, you need to know the difference between an activity tracker and a fitness device. They are starting to become one-in-the-same for the most mainstream brands, but there is a clear difference and this will hopefully help you when you are deciding what to choose.

Activity Tracker

An activity tracker does just what the name implies; it tracks your daily activeness or lack-there-of. At the most basic, an activity tracker will tell you how many steps you have taken. Most however include sleep tracking as well. Once you start going up the line, you will get automatic workout tracking, integrated or external heart rate tracking and other metrics related to your steps, such as stairs climbed and inactivity periods.

It should be noted that if you are not a huge fitness person and you just want to track the basics because you either something to keep you on point with hitting your step goals or achieving some level of activity toward health or weight goals, then an activity tracker is key. And most companies are hitting up these devices with extremely stylish designs. For example, Withings has an activity tracker watch that is really slick, the Activite Steel and Saphire. Garmin just came out with one as well, the Vivomove; and it's probably the most attractive looking activity tracker I have seen yet.

Other devices can track activity as well, like smart phones and smart watches. So, your iPhone or Android phone will probably have a step tracker app or you can get an app that can utilize your phone to track that. But Apple Watch and Gear S2 can track your workouts like mainstream fitness devices, right? Yes and no. I leave the super technical details to DC Rainmaker, but basically these devices are not the best when it comes to true fitness tracking. The have severe accuracy flaws. Now, there are some 3rd party companies that have apps to correct some of this, but overall, if you are training for races or have a huge focus on working out, then an activity tracker is going become very limiting at some point.

Fitness Device

And now the fitness device. This is a device that is purely designed for tracking detailed metrics about your workouts. This can include heart rate min, max, average, and zones, calories burned, intensity levels, elevation changes, distance, speed, instant pace, and the list goes on and on. Now, thanks to FitBit being so competitive, they forced companies like Garmin, Polar and Tom Tom to incorporate activity tracking into their newer devices. So nowadays, a fitness device usually has all of the activity tracking components in addition to everything it already has and is designed for. This basically gives you an extremely detailed and advanced device that will give you a holistic look at your day-to-day lifestyle and the impacts of your workouts, activities, sleep, and more.

In addition, thanks to Apple, many fitness devices and activity trackers alike are incorporating smart features now as well; apps, music control, message alerts from your phone, and much more.

How Do I Choose?

This is fairly simple in most cases. If you are just trying to be active or you have goals set by your work, then a standard activity tracker will meet all of your needs and then some. However, if you consistently workout by doing running, cycling, strength training, swimming, other, or a combination of them, then you will want a fitness device so you can see metrics specific to the workout you did so you can keep improving for whatever goals you have. This is not to say that a fitness device wouldn't be good for someone who is just looking for standard activity tracking, but it will definitely give you way more than you want or need...although for some of the extra smart features or style, in some cases, it might be worth it.

Summary

This was a short article, but I wanted to make sure you understood the top level difference between devices before I start going into more details on which ones to buy, how to customize your ecosystem, and more. Up next I will be discussing calories burned across activity trackers and fitness devices.

Choosing a Health and Fitness Ecosystem - Part 1 - The Basics

The Basics

If you don't have a naturally fit and healthy lifestyle, then it may be a struggle to figure out what you need to help motivate, track, analyze and progress. There fitness devices, smart devices with fitness features, apps for smart phones, websites, software, and much more. Not only that, each group has typically no less than a dozen or two companies / brands you can go with. This alone makes wanting to track what you do intimidating and can stop you before you get started.

So, let's cover a simple checklist to help you navigate this crazy world of health and fitness. As a note, I will be doing more in-depth posts on various options, ecosystems, and advice to blend your lifestyle into the ecosystem you choose.

What Do I Need to Get Started?

You need to first ask yourself, "Do I really care about tech and tracking as a way to motivate myself?" If the answer is no, stop reading and go get healthy! If the answer is yes, which is how it is for most people, then let's figure out what your initial motivation is.

Most people want to be healthier or improve something about how they look and/or feel. Some people also have major health issues that should be addressed. However, this isn't always enough to get going. Once you decide to get going, you then need a way to keep yourself motivated.

We'll start with the easiest and fastest growing motivator: Your job, school, or coach has laid down the hammer and said you either have to be more fit and healthy, or there is some awesome financial perk to being fit and healthy. This is the easiest to address. In most cases, especially with companies, there is already some tool that the company is going to use, such as Viverae or Shapeup. Almost all of these tools link to other fitness or tracking websites and electronics. The most common examples are MyFitnessPal and FitBit. So, if your company is your motivator, your ecosystem is simple: Use what they have, get a fitness tracking device that will connect to that ecosystem, and if you plan on tracking nutrition, either find a site that allows you to track what you eat or utilize the site of the fitness device you got, assuming they offer food tracking.

Let me give you a common scenario. Let's say your company uses Viverae. Their portal allows you to track sleep, steps, activities, and nutrition. Most companies who have this setup also offer company stores or discounts to activity trackers, the most common being FitBit. FitBit is a one-stop-shop for general activity, health and fitness tracking. For example, the FitBit Flex HR will track you steps, sleep and activities. This data will automatically (once you set it up) sync to the Viverae portal. In addition, FitBit's website and app allow you to track your nutrition as well. This also syncs with Viverae. You can also get a FitBit scale that will get your weight and other vitals. This can also sync with Viverae. You now have an all-inclusive ecosystem with minimal effort:

1. Viverae Portal to show all progress for whatever bonus you will get from your company
2. FitBit Device
3. FitBit Application and Website

That's it! It's not as intimidating when you see it that way.

But I Do More than Just Health and Fitness for Work, School, or a Team

That's fine. And maybe you already have fitness devices or activity trackers you currently use. This can be both an easier and more complicated scenario. If you are using one of the major brands, like Garmin, FitBit, Jawbone, Under Armour, Polar, or TomTom, then those companies already sync pretty well with other websites and portals. In regards to nutrition and health tracking, if you are using one of the major ones like MyFitnessPal, then that syncs with all of the major activity and fitness tracking brands. Therefore, for those who are doing multi-sport, activities other than walking/running, and so on, there is an easy way to sync everything up.

Now, the caveat here is that you may need to be using multiple sites and apps to see everything, but it's still rather minimal. Here is an example of a common scenario for someone who does multiple sports in addition to nutrition tracking.

1. Garmin VivoActive HR
2. MyFitnessPal
3. Withings Scale

This scenario is very common. And it's also the easiest to manage. Now, there are other sites you can sync your data to for a different or more in-depth look at your workout and health data, but that is completely optional. However, let's say you have a device that doesn't sync up well with other sites you want to use. There are websites out there that will sync with virtually anything that can give them data. In turn, they will then format that data and send it other sites you use. So, if your fitness device doesn't sync with MyFitnessPal, for example, you can use a site such as tapiriik.

In Summary

Ideally, you want to stick with an existing ecosystem, especially when it comes to devices. So, if your planned support group all use FitBit, and FitBit's devices meet your needs, don't look any further. If you have tons of friends who have all sorts of devices, find a site that can sync with all of them, and then get whatever device looks the nicest or is the easiest to use. Up next I'll cover the difference between an activity tracker and fitness device, and how to choose the right one for you.

Improving Your Running Speed

What is the best way to become a faster runner? Well, run faster of course. From a very generic standpoint, it actually is that simple. If all you did was keep trying to improve your time for a specific distance, you will start getting faster. However, there is usually a plateau point or a point that the gains are so minimal, they don't really seem to exist. Therefore, you will need to put a little more into this effort.

Intervals

Interval training basically handles it all. I will touch on some other stuff later, but it plays such a small role it's not even worth mentioning before I explain intervals. To start, you will want to incorporate 2 interval runs into your weekly running routine. You can decide when to do this, but I recommend not the day before or after your long run.

The purpose of intervals is to run shorter distances at a faster pace. For example, if you only run 5k races, then your interval sessions will probably only total a couple miles. So, you may run a bunch of 200m sprints, with 50m recovery walks or jogs in between each sprint. If your current 5k race pace is 10 min/mile, then you will probably try and shoot for your 200m time to be in line with maybe an 8:30- 9 min pace. You can of course go as fast as your body will let you without getting hurt, but I am trying to be conservative here. So, this 9 min pace turns out to be about a 1 min 8 second 200m sprint (200m is 1/8 of a lap at a track, 400m is a lap or a quarter of a mile).

On your other interval day you may want to do a mix of 200, 400, and 800m sprints, with maybe 50, 100, and 400m recovery walks or jogs. Then, after doing this consistently for a while, you will start noticing your mile time drop significantly. The change doesn't happen over night, but most people start seeing noticeable changes in speed within 4-6 weeks after incorporating the intervals into their current schedule.

You still need to do your pace runs and long runs, so you will have to fit the intervals into that mix.

Weight

Weight is an awkward variable that doesn't really play a lot in your speed unless you are already getting into the professional level or you are starting from scratch and are overweight. If you are conditioned to run a certain pace at your current weight, and shave off a significant amount of weight, you should naturally become faster, because you have less weight you are carrying. For example, a 300lb person running a 12 min mile could potentially see their mile time drop to 10 min if they dropped to the low to mid 200's. However, this assumes all other things stay constant; which is almost never the case.

Slow vs. Fast Twitch Muscles

Let's face it, some people were designed to be short distance runners, and others long distance runners. Speed for these 2 types of runners depend on different things; fast twitch and slow twitch. The goods news is that the body is usually pretty balanced on slow and fast twitch muscles. This means most people are capable of sprinting a short distance at a pretty fast pace for a short period of time; and likewise, can run a much longer distance at a much slower pace for a much longer duration. Slow twitch muscles are more geared toward endurance, as they fire slower, thus allowing better use of oxygen consumption. The key here is your fast twitch fibers.

There are two types of fast twitch, Type IIa and Type IIb. The key to improving speed revolves mainly around the Type IIa, which combines the use of aerobic and anaerobic metabolism. You can pretty much call this a sort of hybrid twitch fiber, as it's basically a mix of slow and fast twitch.

Performing intervals for a cumulatively longer distance allows you to improve the efficiency of these fibers. Therefore, as you improve, they are more efficient at fuel consumption, thus allowing you to run at a faster pace for a longer distance.

Summary

There is a lot more to running fast. But this hopefully wets your whistle and gets you interested. There is a lot of science and many more details behind each thing I mentioned above, so feel free to learn more. Have fun, run safe, and speed things up!

On the right track

I accomplished my goal last week; I exercised 3 times. Since I have been out of it for a bit now, I was a little sorer than expected, otherwise I would have gone for a 4th workout. For the most part, I made sure to log my foods. This weekend was a bit tough, but my goal right now is to log 5/7 days, which I did accomplish,

I missed my workout yesterday because I was busy painting and shoveling ice, and I am extremely sore right now. However, tomorrow I will be back into the swing of things. Overall I am doing well, but I can still do a lot better. However, I am very optimistic and progress is progress. Good luck to everyone out there striving towards their goals!

Nike Apps (for iPhone)

I had done a post a while back on NTC (Nike Training Club) and I figured it was time to just talk about Nike's other app offerings for iOS.

• Nike+ Running (Free)
• Nike+ Fuel (Free)
• Nike Training Club (Free)

As you can see, the theme here is "Free". For now, I have a review on Nike Training Club you can check out.

The main reason for bringing up Nike+ is that it's still a very strong community and they have great tools to really help people succeed. There are tons of alternatives out there, and yes, Nike+ isn't as much of a focus anymore since Nike discontinued the FuelBand and there hasn't been as much focus on Nike+ from Nike.

So let's dive in! The main reason I like these apps is because they are really well built and useful. Aside from being required to create a Nike+ account, there really isn't any downside I can find, unless you are someone that needs extremely detailed statistics. Nike has designed their apps more around the idea of social fitness and the average user. This means that someone just starting out won't get overwhelmed by too many features and screens. In addition, the learning curve is fairly flat, so if you know how to use your iPhone, you can easily use these apps.

The other reason is that I love the way Nike has built the social and rewards aspect so fluidly into their apps and site. One of the hardest things for people to do is stick with a plan to improve fitness, have a healthy lifestyle, achieve a fitness goal, or the like. One of the easiest solutions is to take the journey with someone, which is easy to do with Nike+. You can setup goals, challenges, and share your progress.

In regards to additional tracking, you can link your Nike+ account to other 3rd party sites / apps; some popular ones include MyFitnessPal, Garmin, TomTom, Apple Health, Google Fit, and more.

So, now for a brief overview of each app, which I will have follow-up posts on more details for Running and Fuel.

Nike+ Running

This is basically your standard app that allows you to track you run; indoor or outdoors. You get standard information which is very important to beginner or seasoned runners / walkers. First off, you will be able to track your distance, total time, and average pace. In additional, you will see your total count of runs, total miles overall, Fuel Points, and how you rank compared to friends (assuming you use the social piece).

One thing I always loved was how you could integrate your music into your run. You can create a Pace Station which allows you have you music sync up to your pace to keep you motivated and consistent. This is partnered through Spotify. Or you can just select a playlist you already have.

During your run you will get alerts, such as each mile completed, as well as be able to see your current distance, average pace, heart rate if you have a bluetooth HR monitor, and elapsed time. You will also see what song is playing and have the ability to change tracks.

Once completed, you can add a picture if you want to make the session more memorable. For example, if you are running a race, you could add a finish line selfie. Finally, after your run, you will see a map of the course you ran/walked, total time, average pace, elevation gain, average heart rate if you used a HRM, how you felt after the run, the temperature, and the current mileage on your shoes. You can also share your session with all of the popular media sites.

I want to mention that if you are using a FuelBand or an iPod nano, you can utilize this for indoor running. Now, it is not the most accurate, but you can get a foot pod which is surprisingly accurate for tracking. However, it's best for steady paces, and does not do well with large fluctuations in pace. Interval training works well though.

I also have to mention Apple Watch. You basically have the same functionality, but on your watch. As with most apps, you will need your phone with you for GPS and HRM.

Nike+ Fuel

If you still have a Nike FuelBand, then you use this app to sync all of your information. As a note, I am pretty sad Nike got out of the tech arena, as the FuelBand and their GPS watch really set the tone for the current wearables market today. Anyway, the app is very standard for any activity tracker; shows you steps, activity levels throughout the day, and your Fuel Points. You can view extra detail on your activity level as well; viewing day, week, month or year. You can view your progress, how you are doing on your goals that you defined, and how you are doing versus others. In addition, you get social updates your friends. You can also see you summary of all of your training sessions. This app integrates with NTC for activities. In addition, you can use your iPhone 5 or later if you don't have a FuelBand. You pretty much track what Nike calls Nike+ Sessions.

Nike+ Training Club - NTC

As I noted above, you can read my full review on this app. Basically, it's a fitness trainer on your phone. The app includes workout plans for all types of goals and personal schedules  (I love the 30 minute workouts). The app syncs with your music, gives you alerts and counts reps for you. In addition, if you aren't sure how to do a move, there is a video for every move to show you proper form and technique. There are tons of paid apps out there, and yes, there are many apps you can customize your workouts to your heart's content, but there are still few apps that offer such a solid and well rounded set of workouts for FREE! I still use NTC a bunch, but being a triathlete, I typically use apps that allow for fully customized workouts, such as Fitness Builder.

As you can see, Nike really offers a 1-stop shop for anyone who wants to get fit and healthy, or for anyone who is seasoned and needs solid and reliable tools. Enjoy!

Now for the Kick Start

Last week when I said I was going to try and do some sort of workout in between cooking, I was successful! I didn't do much; some push-ups, crunches, and seated dips. But it was better than my usual nothing and I was really proud of myself.

I didn't get any other workouts in over the weekend, but I made sure to be pretty active. Although I was more active on Sunday, I somehow met my step goal for Saturday but not Sunday. At some point I'll have to figure this out. 

This week is going to be a big week for me. I have two major goals: get no less than 3 workouts in, and start weaning myself off of soda, minus the occasional rum and coke. 

Another upcoming goal is going to be to start getting a minimum number of steps per day, which will force me to at least run most days, if not every day. Hope everyone is going to have a great week and hope everyone enjoyed Super Bowl weekend!
