Strenuous Exercise

Strenuous Exercise: Defining strenuous or vigorous exercise is largely a matter of perception, as it depends on how hard a particular activity feels to you. Someone who is out of shape may find a brisk walk quite strenuous while a marathon runner may not find it the least bit challenging. Your heart rate can tell you how strenuous your body considers an exercise to be. In general, the more strenuous the exercise, the faster your heart will beat.

Singles tennis, jump roping, running, jogging, race walking and aerobic dancing are a few examples of strenuous or vigorous exercise. Hiking uphill with a loaded backpack or bicycling at least 10 mph are also considered to be strenuous and may seem extremely strenuous if you are ordinarily sedentary. A hint that you are engaging in strenuous exercise is that you'll have to stop and breathe every few words during conversation.
