I have a problem making mind muscle connection with my left forearm who only measure 12,6 inch (the right forearm measures 13,5 inch)and i cannot recruit the muscle fibers because i don’t have enough muscle mass to contract it.
I do lots of wrist curls( i can do BB wrist curls with 155 pounds for 5 reps) but i cannot make the mind muscle connection with it and sometimes i have wrist pain i think because my wrist take most of the pressure.
By the way i’m 6’0 and i have 210 pounds.
probably like sh3 wrote my right forearm is doing the bulk of the work .
I think i will isolate just the left one with DB wrist curls and concentrate more.
Thanks.
