I did crdio yesterday for 25 mins, and my legs are really sore. I did running on a treadmill, stairclimbing in my house, and jogging in place with weights in my hands. Most of my body is sore as I have been in a while. Is their any other cardio that I can do? I am thinking of doing some sort of aerobics or fighting for like 7 minuets. Any other ideas?
