>>if u notice after heavy deadlifts its really hard to do situps and other ab excercises for a reason.
>yeah, the same reason it's real tuff to do curls after working up delts - psoas was used very hard
>delt works to uphold humerus vertically in curl

because long head biceps tendon facilitates stability of shoulder joint
i noticed biceps hurting when i was hand drilling shit back when i was benching retard and always had achy "shoulders"

it WOULD be perfectly sensible advice if biceps curls didn't aggravate the same condition - injured biceps
>how so?
shoulder long head biceps tendon gets trapped under front delt in all variations of biceps curls (preacher included) cause delt is upholding humerus vertically in isometric hold during biceps curls - tendon in shoulder can't slide freely and u get no biceps and tendinitis if u try your best
>what do? can't curl can't pushup either it's all fucked up if i try hard .....
sit on bench sideways and lean on elbow - this fixates humerus in place and relaxes delt, i like to not even hold the dumbbell just balance it near wrist with other hand, this doesn't fuck up biceps and grows forever elusive long head - that biceps peak u alwayas wanted
