Every mon, and fri I add some iso workouts to my compound movements to increase size and strength of my arms. For biceps I do standing strait bar curls and my reps are 8/6 with as heavy weight as possible, followed by weighted chins 3x5 with increasing weights frequently, then finalizing with ez bar preacher curls same format as standing curls but with close grip. For triceps I first do close grip bench press two sets 8/6 heavy as possible, bench press lockouts 2 sets 8/6 on high peg to iso my tris, and skull crushers 2 sets heavy as possible 8/6. Am I over training? I hit them twice a week with no iso in between just compound movements. anything u guys would change or alter to increase size and shape?
