Another factor when it comes to workouts and sweating is the fact that when we become more proficient at an activity, the body adapts. It becomes more efficient, stronger and better able to push harder at an exercise, often leading to us sweating less. For those who are well adapted to high intensity exercise, often the addition of high heat can improve conditioning as the body continues to adapt to the challenge.
Ultimately, when it comes to gauging fitness and the intensity of a workout, the best indicator to use is heart rate. As aerobic fitness increases, resting heart rate decreases and can be a great indicator to check when waking up int he morning. Once you have an idea of your baseline, you can see it decrease as you get fitter and in better shape. From there, the mark of a good workout is one that sees the heart rate elevate during exercise. Similarly, if you’re looking to improve fitness, you want to time how long it takes after exercise for your heart rate to return to its resting rate. The quicker it goes back to normal, the fitter you are.
Still, any exercise is better than none and even workouts like barre or yoga that might not elevate the heart rate quite like a spin class or treadmill session have their benefits, like improved mobility and flexibility. So, you don’t need to sweat to get a good workout in, plus it makes the dash from the gym to the office that much faster.
