I work out at least every other day, religiously for 15 years now, I'm 49 In the summer, I'm most active, maybe 5-7 days a week, just depends.
I do these every other day, never miss, ever...
yoga BEFORE EVERY workout, at least 15 minutes. Might be the best thing I do.
10 minute trainer workouts with Tony Hornet
Stationary bike in basement & watch TV
Lean muscle lifting weights, mostly hi rep 12s,15s, and 20lb dumb bells
Extra weekly workouts include...
Hardcore Mt biking outings 3 seasons a year (used to be 4, just can't do snow anymore!)
Golf, still walk and carry my clubs, I'm 49 & it ain't as easy as you think
Toss the football, baseball, and frisbee with my kid all the time. This is an awesome work out
Play street ball with my 15 year old & can still blow by him.
I can go on all the activities I do, but the idea is to stay active, everyday. And, to do the top items every other day, NO MATTER WHAT, so that I can do the other "fun" things on the odd days. Keeps me strong and limber to remain active at a high level.
I park in the farthest spot in any parking lot & then run into the store, every single time. Sounds silly, but I bet most adults couldn't do it without maxing out their heart rates & I don't care how old they are. Just another thing I do to stay in shape...stay active & your body will respond. Just that simple I think...
