Using a tracker to monitor your body’s response to group exercise can be insightful and motivational too. Les Mills Trainer Jim Berg explains how to track your heart rate for best effect.
If you choose the right group fitness workout there’s no real need to track your heart rate – the workout will be scientifically shaped and tested to push your body into the right heart rate zones at the right times. But heart rate tracking can still be very valuable. Les Mills Trainer Jim Berg says that monitoring your heart rate is great for feedback, motivation and keeping check on your training load. So we asked him more about how to do it right.
Why should you start monitoring your heart rate during group fitness workouts?
By becoming familiar with your heart rate during a specific workout you’ll see from session to session if you are improving and pushing yourself as hard as you should. You’ll learn when you can push harder, and when you need to recover during the workout. You´ll also be able to detect early warning signs if something is wrong with your health or your stress-levels.
With a heart rate monitor it’s easy to learn, grow, and improve your understanding about how your body responds to exercise. It is great for reflection and comparison, so that you can monitor fluctuations and establish norms. It is also particularly valuable if you’re a fan of high-intensity interval training, as recent research
highlights the importance of avoiding too much time in the 90 percent-plus max zone.
So how can you adjust your workout if you’re doing a structured group fitness workout?
In a group fitness workout everyone is doing the same thing and truly experiencing the “group high”, but that still leaves a lot of room for personal variation. Les Mills Instructors will always provide options so you can always adjust the intensity by choosing easier or harder options depending on your training objective.
What are the common misconceptions about heart rate training?
The idea that more is better – that your heart rate should be high throughout a workout – is definitely one misconception. Another is the concept of using heart rate as a “high score” where the only goal is to achieve a specific heart rate and not consider the overall picture; what the heart tells you together with how you’re feeling and your knowledge about your own body. You should use your heart rate as just one tool to train smarter, and not aim to “hit the jackpot” based on heart rate alone.
What’s the one thing to know about heart rate monitoring that most people don’t?
Maximum heart rates vary a lot, so setting training zones based on values determined by the rule of thumb – 220 minus your age – won’t always deliver the opportunity for accurate monitoring. That the main factor for controlling and adjusting workout intensity should be based on your individual threshold and daily capacity, not maximum heart rate. If you’re really serious, having your individual threshold determined in a lab will allow you to accurately monitor which training zone you are in.
What is the biggest mistake you can make when interpreting heart rate data?
Thinking that “more time in red is always better”, and not comparing it to what you’ve done before. The best proof that you are fitter than before is when you are able to maintain a higher heart rate for longer than you used to, or when your heart rate is lower while running or cycling at the same speed or output. So you need to look back to look forward, and determine how you are tracking.
So, heart rate monitoring is clearly valuable, but also part of a bigger picture
Yes, it´s a truly great way to improve your understanding of your personal physiological response to exercise over time. Even if you’re not a tech geek who gets obsessed with the training diagrams and charts that are available, it’s a great, simple way to capture more feedback than simply how your workout “felt”.
