This 7-move routine will give you the back you’ve been looking for

Six-pack abs for the front, traps for the back. If we had to pick one vanity muscle for your back, the trapezius would be it. Long and triangular, this muscle rides from the base of your neck, across your scapula, out to your shoulder tips, then down your spine to your mid-back. Given the real estate it covers, it's no wonder it can give your upper back awesome definition when properly flexed.

Of course, that's not the only reason you should give your trapezoid muscles a workout. The traps hold the key to just about every upright functional movement you want to perform, from carrying kids to lugging groceries to changing lightbulbs (seriously). These muscles give your spine and shoulders proper reinforcement and provide the tension that prevents you from slouching over at the end of a long day of work.

If you've never found yourself saying, "Hey, let's make today a traps day!" Then this trap workout is for you. A 15 to 20-minute, 7-move routine, you can add it to the end of arms day, or work it in after a bout of cardio. Do it three times a week to see major changes in about a month.

1. Barbell shrug

Works: Upper traps

Stand with feet shoulder-width apart. Hold a barbell in front of you, arms extended, using an overhand grip. Keeping your arms straight, shrug your shoulders, raising the barbell several inches as you do. Relax. 8 reps, 2 sets.

2. Diver pose

Works: Lower traps

Holding a light dumbbell in each hand, bend knees and hinge forward at the waist so your back is flat and parallel to the floor. Raise arms out in front of you in a Y shape, like you're getting ready to dive into a pool. Hold five counts. Release. Repeat 8 times.

3. Farmer’s carry

Works: Upper, middle, and lower traps

Holding a heavy dumbbell in each hand, arms straight by your sides, walk around the room. Focus on keeping your spine straight and shoulders back. 60-second walks, 3 times.

4. Lateral lifts

Works: Upper traps

Stand with feet shoulder-width apart, a dumbbell in each hand. Holding weights vertically (north/south orientation), raise your arms out to the sides. Hold for two counts, slowly lower. 10 reps, 2 sets.

5. High pulls

Works: Lower traps

Stand with feet hip-width apart about three feet from the cable pull. Position the pulley at head height. Using the Y-handle, pull the cable directly toward your head, squeezing your shoulder blades together as you do. Hold two counts, release. 10 reps, 2 sets.

6. Overhead carry

Works: Upper, middle, and lower traps

Holding a heavy dumbbell in each hand, raise arms straight over your head, palms facing each other. Press shoulders down and keep your spin straight as you walk around the room. 60-second walk, 3 times.

7. Row machine

Works: Middle and lower traps

Get your cardio done along with your traps toning with 10 minutes on the erg. Focus on fully extending your arms in front of you as you push back with the quads and feet first, then squeeze your shoulder blades together as you pull the cable to your chest. The speed of your rowing motion will raise your heart rate, but for muscle building, it's more important to think about good form.
