57 here and I still do them. Altho I can't get four sets of 10 in anymore. Maybe 10 on the first set then lucky to hit three or four on the fourth set. It's a part of my rock climbing regimen.
What's killing me is I may have to stop running. 40 years of distance running may have contributed to some migratory arthritis in my feet.
Still mixing up some cross fit, cycling, climbing and subbing elliptical for the running trails. I reckon if I make it to my 70's I'll have to settle into some low impact yoga to stay fit.
