This 2-minute shoulder drill won't be fun. In fact, it'll feel a lot like punishment, says Men's Health Fitness Director BJ Gaddour, creator of the 20-minute equipment-free Bodyweight Cardio Burners. Watch the video above to see how it's done and give it a shot for yourself.
Need some help pushing through the torture? Think about how a broad set of shoulders can work wonders. By training them, your arms look bigger, your back looks thicker, and your waist looks slimmer. And the stronger they are, the more weight you'll be able to move during chest, back, triceps, and biceps exercises.
And if that doesn't help you, then try screaming like your shoulders probably are right now.
