Hi there,
Just wondering, how important is upper body positioning on SLS/PE4?
I notice that my upper body comes forward as I go down, whereas the athlete in the video keeps his upper body pretty much perfectly upright.
Does my upper body have to look like his for my reps to count?
And if I do have to have a perfectly upright upper body, is this a strength or mobility issue? Or both?
Any tips/feedback is appreciated.
Thanks!
