I used a recumbent bike for my cardio. I do 70 minutes a day 4-5 days a week. I keep my HR around 135 bpm and sometimes max at 155 toward the end. I find my legs being very sore. 2 of those days I will ride 10 minutes and then do 25 push-ups and just back and forth and I wind up with a total of 175 push-ups. I figure it's good to throw the heart a little curve ball anyway. I also do bicep and tricep work 1 day a week.

As many of you may or may not know, I cannot use any heavy weights because of a bad shoulder and a bad lower back keeps me from other exercises. I do supermans a lot for my lower back to try to make it stronger and am working up to other exercises.

Anyway, if my legs are sore from riding... would more protein be a better idea? Perhaps there is some growth i'm missing there?
