I consider myself to be in a fairly good shape. Not an athlete by any means but I jog, lift weights, bike, run, dance, hike - probably your typical west coaster
But every time I try to amp up my workout routine and try Insanity, T25 and P90X, I get work out to the point of exhaustion, and it takes me DAYS to recover from it. Once I caught a cold right after I did the workout! I eat well, sleep well and make sure I get my "fuel" pre and post workout. It's almost more detrimental than beneficial to do these workouts since I'm out of it for a while afterwards.
Anyone has the same issue?
