shoulder flexion and deslocates

Hi!

i have a question about shoulder flexion:

when i am doing the HS PE3>im with shoulder lenght grip, i deslocate my shoulders instead of flexing. Should i close my grip? if yes what is the degree of flexion i am looking for?

thanks very much,

best ,

Nuno Duarte

anyone??

thanks,

best

There shouldn't be any dislocating on this one. Should be pure shoulder flexion. 

Reduce the grip or increase the weight until it is impossible to dislocate.
