If you’ve ever taken part in a class at Fit Fx, you’ve surely heard your coaches talking about members getting in to the “red” heart rate zone. So, why does it matter where your heart rate is at when you’re working out? There are actually several very important reasons to understanding heart rates and why you should be working out in certain heart rate zones!
heart rate zones
First, let’s understand the concept of the heart rate zone. At Fit Fx we encourage members to use MyZone heart rate monitors, which divide zones up by color and percentage of your maximum heart rate. The great thing about a MyZone belt is that it is designed to learn your heart rate and make this an even more exact science! What’s even better, we sell the belts at cost here at Fit Fx!
Heart rate zones are broken down into the following color-coded categories: Gray (under 60%), Blue (60-69%), Green (70-79%), Yellow (80-89%), and finally the famous Red zone (90-100%). These percentages represent how hard you are working in terms of beats per minute of your calculated maximum heart rate. In other words, the faster your heart is pumping, the higher the percentage! The more we work out in that higher zone, which is where we reach our VO2 max, the more Fit Fx effect we get, otherwise known as Excess Post-Exercise Oxygen Consumption (EPOC), which allows us to continue burning calories at an elevated level after we are done with class!
Aside from making sure we get the calorie burn benefits, there are also safety benefits to knowing the heart rate zones. It is important for you to know the zones that are safe for you to be in, but also for your trainer/coach. Knowing when to reach those elevated levels and then when to allow the heart rate to come back down is a very important part of High Intensity Interval Training, which is what we do here at Fit Fx.
When it comes to results, its also key to know the difference in aerobic vs anaerobic heart rate zones. You do not need to be going at full throttle on every exercise you do! We have designed the workouts for you to spend time in both an anaerobic and aerobic state for certain periods of time. Doing so will allow you to get the results you are looking for more efficiently!
You’ve probably heard us talk about the generic equation for knowing your max heart rate, which is subtracting your age from 220. However, there are so many factors that go into this just being a generic equation. To truly make understanding your own heart rate zones more of an exact science, investing in a heart rate monitor is probably one of the better moves you will make if you plan to invest in your health!
