If you're interested in finding an intense arm workout [1] to help you get more defined biceps and triceps and increase strength, an EMOM [2] upper-body routine is a great option. EMOM [3] stands for "every minute on the minute" — these workouts challenge you to complete an exercise for a certain number of reps in 60 seconds or less. 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 workout types, EMOM makes for a great upper-body routine [4] that's dynamic, quick, and never boring. Ahead, find our favorite upper-body EMOM workouts from YouTube that'll get you sweating fast.
