Hi , Joe . I am having the same trouble here . With legs it’s fine , not much of an issue. The high incline Smith press is were i am finding it weird.
At the bottom position it lines perfectly with my upper chest , as i start the concentric , it’s like i am pushing up the slope and it gets away from my body . I am trying to keep the ROM less for this exercise to see if it’s easier .
Any suggestions? Should i put the bench the other way round and see ? In this way the concentric will be more towards my head
