Take biceps for example as thats one where i can spot myself and really push hard, i cant get any stronger. Ive pushed very hard doing single arm curls, spotting myself when necessary, and i dont get any stronger. I'm told my arms are big, but i get the feeling if i can break through this strength problem, i could go to the next level.
Chin ups are another thing ive struggled to gain any strength from, in fact, i cant gain any strength with them at all. I do 3 sets and the first i can manage 6 rep, then the last two its 4 or 5 reps. After months of trying, i couldnt gain one bloody single rep.
If i train right, like u suggested, i get slight gains in dips, bench, dead lifts and leg press, but not arms, back or shoulders.
Thanks for your reply Hulk.
