As a physical fitness course for college, I decided to take power walking, two hours a week, every Friday. Now I'm looking up information about it, but can anyone tell me anything about it? I heard it's a great way to get in shape, but is there anything else? Any information on it would be helpful.
Also, as silly as it may sound, I've been doing jumping jacks. 300 a night. I find after doing it I'm really refreshed and feel better.
Is there such thing as too much cardio? What are the consequences?
