What work out do you do? I do Mentzer 's H.I.T.
Shit I don't know what you would call it. It's a combination for exercises from physical therapy sessions throughout the years. I have gone for my back, knees, shoulder.
So lots of core stuff. I do planks and medicine ball for abdominal in all sorts of ways. I do arm bands, and even leg band excises. I have free weights for culrs and lunges while wearing ankle weights. Pushups and wheel barrel type exercises. Burpees. And even got ideas from HHH exercise video. Yeah what a "mark", but they work.
I do about a 2 hour workout twice a week, and outside of that just walk a lot and do tons of stair climbing. I feel ok and at my age I can't do the heavy weights anymore. So much of this shit is to keep my body from falling apart. It takes me like 45 minutes to be really warmed using the foam roller and yoga type poses, but I do what I gotta do.
