Tried my best to do it without a real barbell, Feet are aligned with the shoulder. conventionnal deadlift.
@DctMuscle Your form doesn't look too bad at all - obviously it is a bit awkward using a pull-up attachment rather than a barbell.. haha.
The one thing I notice is your shoulders look awfully tight and rolled forward - it's almost like you have them in a permanently shrugged position. I would try to roll them back a bit more and pump that chest up - this will help you 'tuck your lats into your pockets' and will help when you start adding weight.
The other thing would be to make sure you really flex and squeeze your glutes at the top of the movement. But aside from that, form is looking good!
It feel great that you actually answered! It Amazing! Could it be that my shoulders are pushing too much toward front hindering my ability for the shoulders to tuck easly behind ( it really hard to do) might be the pull up attachment.
It might be easier with a barbell, yeah. All you need to do is roll your shoulders back, retract them, and engage the lats when you grip the bar to keep them from rolling forward. See if that does anything to that mid pack pain you've been having.
