Strong back muscles are essential for supporting strong muscles on the front of the body (abs and core muscles, we’re talking about you!). Plus, strong back muscles support good posture and can help keep chronic problems, like lower back pain, at bay. “Our back supports us, allowing us to stand, bend over, and basically perform all necessary human action,” explains Eric Botsford, a National Strength and Conditioning Association-certified personal trainer and a frequent participant in high-level fitness competitions like the CrossFit Games and Tough Mudder events RELATED: Everything You Need to Know About Exercise and How to Stay Physically Fit And we shouldn’t be taking the ability to do those types of basic movements for granted. “Humans are sitting more than ever — and, as a result, our backs have become weaker and therefore more prone to injury,” Botsford says. Eighty percent of adults are likely to suffer through back pain at least once in their lives, according to estimates from the National Institutes of Health. (1) “Keeping the back healthy and strong is the key to living a long and full life independently,” Botsford says. Some major back muscles you want to keep in good working order for posture, range of motion, and mobility include the trapezius, latissimus dorsi, rhomboids, erector spinae, levator scapulae, and several deeper-lying muscles that run parallel to the spine.

Do that twice a week, and as you get stronger, aim for three times a week. You’ll need a pair of heavy weights (or heavy books that are approximately the same weight) and a pair of light or medium weights (or canned goods).

Beginner Circuit

  1. Hip Hinge Hold via GIPHY Stand with feet hip- to shoulder-width apart, arms at your sides. Keep knees slightly bent (rather than locked), and keep shoulders pulled down (rather than tensed up toward your ears). Keeping your lower back naturally arched, push your hips back as far as possible and lower your torso by hinging at the hips. Lower until your torso forms a 45-degree angle with the floor (or as close to it as you can get). Hold for 30 seconds, then reverse to return to start.
  2. Hollow Hold via GIPHY Lie faceup on the floor with legs long and arms extended over your head. (Increase the intensity by holding weights in your hands.) Press your lower back into the floor as you lift your arms and legs so your body forms a C (your shoulders and feet should be hovering several inches above the floor). Squeeze abs and butt muscles and hold for one minute.
  3. Dumbbell Deadlift via GIPHY Stand with your feet hip-width apart and hold a dumbbell in each hand in front of your hips, with your palms facing your thighs (choose the weight that feels best for you). Squeeze your shoulders together, then hinge at the hips to bend over, lowering dumbbells along the fronts of your legs until your torso is parallel to the ground. Return to standing, focusing on shifting your body weight down through the midfoot as you do. Repeat for 30 seconds, paying careful attention to form and not rushing any part of the movement.

Intermediate Circuit

  1. Dumbbell Bent Over Row via GIPHY Stand with your feet hip-width apart and hold a light- or medium-weight dumbbell in each hand at your sides. Hinge forward at the hips until your torso forms a 45-degree angle with the floor (or as close to it as you can get), allowing the dumbbells to hang below your shoulders, wrists facing in. Pull the dumbbells up next to your ribs, drawing your elbows straight back and keeping your arms in tight to your sides. Slowly lower the weights back to starting position. Repeat for 30 seconds.
  2. Dumbbell Reverse Fly via GIPHY Stand with feet hip-width apart and hold a light- or medium-weight dumbbell in each hand by your sides. Hinge forward at the hips until your torso forms a 45-degree angle with the floor (or as close to it as you can get), allowing the dumbbells to hang below your shoulders, wrists facing in. Keeping a slight bend in the elbows, lift dumbbells up laterally and out to the side until they reach shoulder height. Slowly lower weights back to starting position. Repeat for 30 seconds. Increase the intensity by using your heaviest dumbbells.
  3. Dumbbell Farmer Carry via GIPHY Stand with feet hip-width distance or less apart and heavy dumbbells on the floor beside each foot. Bend to pick up the dumbbells, driving through your heels to lift the weights. Stand tall, shoulders back and core engaged with the weights hanging next to your thighs, and take short, quick steps to move forward at least 50 feet. Turn around and continue walking for a total of 30 seconds.

Advanced Circuit

  1. Single-Arm Suitcase Deadlift via GIPHY Stand with feet hip-width apart, a heavy dumbbell on the floor by your right foot. Bend to pick up the dumbbell with your right arm, focusing on driving your body weight down through your heels to lift the weight up until your torso is back in an upright, standing position. Slowly lower the weight back to the ground. Continue for 30 seconds, then repeat on the opposite side.
  2. Dumbbell Swing via GIPHY Stand with feet hip-width apart and hold a heavy dumbbell with both hands, gripping from the top. Push your hips back, knees slightly bent, and lower your chest to bring the dumbbell between your legs. Push your hips forward to slowly swing the dumbbell up to shoulder height. Reverse the movement, slowly swinging the weight back between your legs. Continue for 30 seconds.
  3. Dumbbell Plank Lateral Drag via GIPHY Place a dumbbell on the left side of your body, choosing the best weight for you. Start at the top of a pushup position by placing palms on the ground, directly below your shoulders, and walking your feet back until your body forms a straight line from shoulders to heels above the ground. (If you can’t support your weight, drop down to your knees, so that your body is in a straight line from your shoulders to your knees.) Reach your right hand under and through the left side of your body to grasp the edge of the weight, then slowly drag it and place it on the right side of your body. Return your right palm to floor, grab the weight with your left hand, and slowly drag it back to the left side of your body. Continue alternating for 30 seconds.
