This Upper-Body Workout Is All You Need to Build Strong Arms and Shoulders

This classic arm move is a must-have in your upper-body workouts. It strengthens your biceps, the muscles on the front of your upper arm. Be careful not to use momentum here — control the movement of the weight going up and down.

How to Do a Biceps Curl:

• Start holding a dumbbell in each hand at the sides of your body, palms facing forward.
• Keeping your elbows close to your sides, slowly raise the dumbbells to your chest.
• Moving with control, lower the dumbbells to the starting position. That's one rep.
• Do three sets of 12 reps, alternating with Exercise 2.
