Why it works: “I like it because it uses your shoulder and arm muscles,” McCall says. You want to train both arm and shoulder muscles across the shoulder joint for peak functional strength, he says. After all, these muscles are connected. Plus, uppercuts are different enough from curls that they feel like a good break from the typical routine.
How to do it: Holding a light dumbbell in each hand, start with your elbows bent at 90 degrees and fists facing the ceiling – like you’re about to do a bicep curl. Starting with your right arm, punch the weight upward, and keep the bend in the elbow. Repeat on the left side. Continue for 30 seconds to one minute.
