Want to develop stronger, more defined arms? The kind of vanity muscles that fill out the sleeves of a T-shirt or polo? Focus on your biceps, triceps and shoulders. This quick and easy-to-master workout guarantees bigger arms with all the right definition. And best of all, it only takes a few minutes. Known as a tri-set, you perform the three moves back to back with as little resting as needed for five minutes straight.
Sometimes referred to as a “triplet” by some trainers, the idea is the same: Three slightly different exercises that work the same muscle group in dynamic ways. The purpose is to utilize these movements and momentum so you force the muscle fibers to stretch and tear, which induces hypertrophy (the name for when muscles get bigger). Start out with five reps a piece, then each time you repeat the workout, try to do one more rep. You’re sure to see fast results.
