I walk at least four times a week and play pickleball 2-3 times a week.
if you’ve not tried PBall, it’s an absolute riot. It’s a very social sport and it’s as intense as your opponent’s skill level. I’ve been completely dominated by dudes in their 70s and I have completely dominated dudes in their 20s and 30s.
Also, yoga is awesome. It is a workout and I find that if I do some yoga stretches before doing other activities, I perform better and am more focused. I don’t do the whole “awwmmmm” thing; just the stretches/balance poses.
