without a doubt
On cold canoing trips, i'll spend upwards of five minutes trying to force my thumbs to crack

Also, cracking defintely warms my hands up.

I can never seem to crack my back, though i've tried, am i doing something wrong?

Hey all, new here….
Do any of you out there notice an improvement (or perhaps the oppostie) in manual dexterity as the result of our mutual habit.
I am a fencer and a ping-pong player, and a good crackin before i hit the mat really makes me feel smoother, perhaps it's just placebo.
