Used to be an avid runner, hills, esp. When I turned 40, we moved to an area where running just wasn't all that feasible (or at least convenient and enjoyable). My health went South anyway.

So, I now workout in the house. Pushups, planks, squats, lunges, resistance bands, etc. I took most of my routines straight off Bodybuilding.com. They have good articles, and numerous videos for good form. One day arms, one day legs, one day abs. If I'm not feeling well, I just take that day off. Not competitive, so I don't worry about it.

Working out goes well with snake videos. Some of the ones I like are, DMExotics, Barczyk (spell??), ViperKeeper. Dave Palumbo, and Kamp Kenan.
