Looking for a good arm workout? You could hit your biceps with some curls, then your shoulders with the overhead press, and finally your triceps with a few extensions. Or you could just do the Triple Crush—which combines all three movements into one exercise to give you the fastest arm pump in the world. Watch Men’s Health Fitness Director B.J. Gaddour perform the combo in the video above. Then grab a single kettlebell or a pair of dumbbells and give it a go.
