alex any tips on breaking the barrier of improving your arms?
Absoluefuckingly.
I've made pretty good gains lately training bi-tri the same day;
Start with heavy barbell curls; but start with high reps and walk your way up to 6 reps range.
Then switch to heavy dips right away, same ranges ~5 sets.
Then go back to biceps and blast back to back sets (maybe 4-5) on a concentration/isolation exercise. when your biceps skin is about to crack, switch to triceps, repeat (triceps extension? or maybe v bar pulldown).
Then go home to post on getbig but roll down your window and let you arm hang as it will be pumped as a house party cauck.
