Ok i have been lifting for about a year i made good gains on biceps early but then focused more on chest back and legs recently ive never wanted huge biceps because im a pitcher in baseball but stronger toned ones would be nice. ive had trouble gaining size on them and there struggling behind the rest of my body. I recently changed up my bicep routine to this
Hammer curls - Lower weight 3x12 but go real slow focus on contractions and the burn these seem to work well
Angled prone curls (incline bench curls to isolate biceps)- Same as above
Chin ups- I recently started doing these so that should help
Any other exercises i can do at my home with limited db's once i start heading to gym more often i will do 21's and preacher curls but what should i focus on to gain more strength in biceps.
