If you're interested in finding an intense arm workout [1] to help you get more defined biceps and triceps, as well as increase strength, an EMOM [2] upper body routine is a great option. EMOM [3] stands for "every minute on the minute," and challenges you to complete an exercise for a certain number of reps in less than 60 seconds. If you finish before the clock runs out, the remaining time serves as your recovery — but if you finish right at the minute mark, you have to go straight on to the next without resting (there's always a catch). One of the most effective interval workouts, EMOM makes for a great upper body routine [4] that's dynamic, quick, and never boring. Ahead, find our favourite EMOM upper body workouts from YouTube that'll get sweating, fast.
