25-Minute Bodyweight Cardio Workout
I hate cardio.
However, I need cardio and so do you.
Cardio training not only burns calories it also trains our most important muscle in the body — our heart.
How hard should you be training?
In order to get the maximum amount of benefits from any type of fitness training you need to hit certain targets.
In weight training, you should be completely fatigued by the end of your set.
In stretching, you should feel the muscle(s) you are trying to stretch, and in aerobic (or cardio) training you should be hitting 60-80% of your target heart rate.
