Tennis is a great sport for getting at all the muscles too. There are guys at the clubs in their 70’s who are more agile than a lot of fellas in their 30’s and 40’s.
Yeah the only thing about tennis is it tends to build too much asymmetry - it doesn’t have to be that way but that’s just the way it’s traditionally played, it creates a lot of side dominance. But it’s definitely a high-pace, athletic sport.
