Question

to improve your cardiovascular fitness, you jog for 30 minutes three days per week. Explain the principle of overload, and describe how you can apply the principles of frequency, intensity, time, and type to improve the workout

Answer 1

Overload refers to the amount of greater load or resistance on the body than it is normally accustomed to in order to increase fitness.

This is not recommended as you might damage up your muscle. Infact whats recommended is that you increase the repetition per set or do it with varying weights and change the type of exercise frequently in order to make the work out more intense and hence, increase fitness.
