I remember reading the Neil Armstrong did something similar while jumping over a fence.
Your finger doesn’t do well when pitted against your entire body weight, and that body is moving.
Exercising or doing anything where there is even the POSSIBILITY of hooking a ring on something is just stupid. It won’t kill you, so it isn’t Darwin Awards stupid, but it ranks up there.
Hubby is a retired firefighter. Never wore a ring at work. Left it on the dresser before he left. He also wore nothing but cheap watches. Our sheriff’s department seemed to get a kick out of running over his. He’d take it off and lay it on the ground to use as a timer while working on someone and after they were stabilized and being loaded in the ambulance whichever deputy saw his watch there would make a point of running over it. Lol. We bought quite a few Timexes.
