If you've managed to add some serious size to your arms, but want to hone in on the finer details—we're talking muscle definition that looks like it's carved from marble—these exercises are absolutely essential. They'll continue to build rock-solid muscle, but give you the subtleties that really stand out. 

How it works

Your typical program consists of a big, compound exercise or exercises followed by isolation exercise, or exercises. For this particular approach, you're going to chill out on the big lifts and double-down on the smaller ones. Isolation exercises are a great way to hyper-focus and zero in on one particular muscle, as well as tap into smaller, more discreet muscle fibers. 

How to work this into your routine

For 2-3 weeks, couple up a large muscle group (legs, back, chest) with a smaller muscle group (shoulders, arms, abs) or a push and a pull. Shoot for 1 day of rest between workouts. Cycle back onto your regular programming after the 2-3 weeks are up. Rest 30 seconds or less between sets.
