Exercising is important for a number of reasons. However, if you want to improve your fitness level it is good to exercise within your Target Heart Rate zone. Do you know how to work our your Target Heart Rate?
There are many way to determine your heart rate from the science lab to the pen and paper. However, the best quick way to get a rough idea is the following:
220 minus your age (this is your maximum heart rate)
You can work out 80% heart rate from this point. However the best fat burning area is at 60 to 70%.
While this is not the perfect way, it will give you a rough gauge. Alternatively there is a site that gives you a good description of working out your heart rate zone using your resting heart rate. http://cyclingdynamics.wordpress.com/2013/09/18/getting-back-on-track-with-a-hr/
That's what I thought. Don't you subtract your age from 220? That would be your maximum heart rate, and aren't we meant to exercise at around 60-80% of our maximum heart rate? There's also the resting heart rate too.
Personal trainers and other fitness professionals are great at helping you work this out. This is usually given at your first session, and/or at your introductory session as soon as you've signed up for a long-term gym membership.
Would other factors such as your BMI also be taken into account?
