Re: Bar Muscle-Up Help!
If you say yours look like a "shoulder shrug," that tells me you're putting the wrong tension on the bar. That is, you're trying to push the bar down and away from you, which should invoke the opposite of a shrug in your trap muscles. Are you trying more to LIFT yourself up? You want to think much more of pushing the bar AWAY from you instead, until you clear enough room to sit through and get your torso on top of the bar. Even though the kipping action is very similar to that of a kipping pull-up, having the ARM action of a pull-up, I think, may be where you're going wrong.
