It's Probably Just The Weight Of Having To Hold His Tablet Up.

A while back I strained my own wrist, slipping slightly while doing a push-up. If I ever complain that I've injured myself in the gym, just assume I slipped slightly while doing a press-up.

This particular injury wasn't serious enough for me to even bother look up which tendon I'd strained. It's mostly fully healed, I'm even back to doing weights and testosterone.

Resting the tiny weight of my tablet in my palm as I scroll though. That's still an absolute killer!
