Yesterday I has this odd idea to try shoulder presses on a bench without back support and ive diecided that for me, this hits my delts much harder than any time i have done it with back support. Understandably I had to drop the weight i was using by about 1/3 to make the lift possible, however i felt it really isolated and engaged my shoulders, which ive always had trouble doing. I thought it might be worth bringing up so others could try it and give their thoughts.
