It seems that pistol squats with are easier with your hands in front of you than they are with your hands behind you. What I don't understand is why.
Like with a front lever or planche or whatever straddles are easier because they're reducing your body length and thus torque. And with situps having a weight behind your neck is harder than having it in front because it seems like if it's in front you can rely on chest muscles to push it up whereas you can't if it's behind you.
But what about pistol squats and hand placement? I just don't get it.
