I hit it year round and have for 30 years. I wrestled in HS and just never quit exercising. Did 5 yrs in the Army in the 90's and turned it up another notch. Now, at 46, I workout 7 days a week and struggle to keep from getting bored. I mean how many hours a week can one man spend on the elliptical machine? I elliptical, run, lift and the elliptical some more. I'm seriously thinking about doing a 90 day P90X cycle and see how that goes. I had a bootleg copy of the program but I think I'll buy the real deal this time and do it right. There's also the CrossFit option. Crossfit has gotten really popular around here and there's a crossfit gym not far from my home. It's also a MMA gym so that'd be pretty cool too. I've even thought about hanging a heavy bag in my basement and beating the crap out of it for an hour at a time a few days week to cut down on the boredom.
