Get Rock-Hard Abs, Sculpted Arms, and a Butt Like J Lo's With These 21 Exercises

We love following Jennifer Lopez's workout content, and she's constantly inspiring us to challenge ourselves with her workouts and wellness routine. When she isn't doing fun, family workouts with Alex Rodriguez and the kids, she's lifting weights to maintain and build strength.

J Lo has given us a sneak peek into her workout routines in the past, and today we're focusing on her arms, abs, and lower body. In the following pictures she shared on her Instagram Story in 2019, J Lo showed us her sculpted biceps and abs, and we have one request for her trainer: share the workout plan ASAP! She also showed off her back muscles and her famous glutes, and we're definitely taking notes.

You aren't going to look like a carbon copy of J Lo, but the ahead exercises are guaranteed to sculpt and strengthen your arms, back, and butt. If you want a full workout plan to build muscle, follow this four-week plan.

J Lo's Biceps, Back, and Booty

01
Bicep Curl

Bicep Curl

The bicep curl will help you get more defined biceps. It also works your deltoids, which are one of the shoulder muscles.

  • Start by holding a dumbbell in each hand at the sides of your body.
  • Keeping your elbows close to your sides, slowly raise the dumbbells to your chest.
  • Moving with control, lower back to the starting position.
  • This counts as one rep.
02
Single-Arm Row

Single-Arm Row

The single-arm row targets your lats, which are one of the largest muscles in the back.

  • Hold a dumbbell in your right hand — 10 pounds is a good starting point — and place your left knee and left hand on a bench. Your hand should be underneath your shoulder and your knee should be underneath your hip. Your spine and head should be in a neutral position.
  • Engage your core, relax your shoulders, and extend your right arm toward the floor. Do not rotate your torso or let your shoulder lower toward the floor.
  • On an exhale, pull the dumbbell up with control, driving your elbow toward the ceiling. Do not rotate your torso.
  • On an inhale, lower the dumbbell back down to the starting position. This completes one rep.
03
Cable Pullover

Cable Pullover

The cable pullover targets your back, chest, and abs.

  • Attach a triceps rope handle to the pulley on the carriage of a cable station. Adjust the carriage so that it's near the top third of the machine. The exact position will vary based on your height.
  • Next, select the amount of resistance you want: 10 to 15 pounds is a great starting point. As you begin to become more comfortable with the movement, feel free to increase the weight.
  • Facing the pulley, grab the rope and step approximately one foot away from the machine. Stand with a slight bend at your hips, knees, and elbow joints.
  • On an exhale, drive your elbows back, pulling the rope down to your thighs. Be sure to keep your shoulders relaxed and your back flat. This completes one rep.
04
Bent-Over Row

Bent-Over Row

The bent-over row targets your lats and rhomboids, which are muscles in your upper back.

  • Lean forward and bend both knees, remembering to keep a flat back.
  • Extend your arms so they are straight. Lift the dumbbells straight up to chest level, squeezing your shoulder blades together as you do. Be sure to keep your elbows in and pointed upward. Don't arch your back.
  • Slowly lower the weights back to the starting position to complete one rep.
05
Banded Assisted Pull-Up

Banded Assisted Pull-Up

The pull-up works muscles in your upper body like your lats, biceps, rhomboids (another back muscle), and more.

  • Place a large resistance band securely around a pull-up bar. A band with more resistance will provide you with more assistance/momentum to pull yourself up.
  • Stand on a stable object (a bench will work), and grip the pull-up bar. With one hand, place the band around the arch of your shoe. Fully extend the banded leg.
  • With a neutral spine and your abs engaged, pull yourself up. The band will provide you with momentum to lift your body up. Lower back down to the starting position.
  • This counts as one rep.
06
Hammer Curl

Hammer Curl

This popular variation works the biceps for a slightly different angle than the basic bicep curl.

  • Stand hip-width apart with dumbbells in hands resting by your sides. Your palms will be inward, facing your thighs.
  • Begin by bending at your elbows and raising the dumbbells up to your shoulders. Keep your wrists straight throughout the movement. Only the lower portion of your arm should move. The upper arm stays stationary, close to your sides.
  • Slowly lower the weights back to starting position.
07
Bent-Over Reverse Fly

Bent-Over Reverse Fly

Work the back of your shoulders and upper and middle back with the bent-over reverse fly.

  • Holding a dumbbell in each hand, stand with your knees slightly bent. Keeping your back flat, bend forward at the hip joint.
  • Exhale and lift both arms to the side, maintaining a slight bend in your elbows and squeezing your shoulder blades together. Then, with control, lower the dumbbells back toward the ground. This completes one rep.
08
Seated Knee Tuck

Seated Knee Tuck

If you want to get more ab definition, you've got to work your rectus abdominis muscles (aka the six-pack muscles). This move will definitely sculpt your abs.

  • Start seated on the ground or on a weight bench. Place your hands about an inch behind your back with your fingers facing forward. Your feet should be on the ground.
  • Lift both feet up off of the ground and extend both legs as you simultaneously lower your upper body. Be sure to get full extension at your hips and legs.
  • With control, bring your legs back to your chest without touching the ground with your feet and return to the starting position.
  • This counts as one rep.
09

Vertical Bench Knee/Leg Raise

This move will strengthen your core while sculpting your six-pack muscles.

  • Position yourself on a vertical bench with your back flat against the back support and your hands firmly gripping the handles.
  • Pull both knees up into your chest, and with control, lower them back down to the starting position.
  • From here, fully extend both legs and lift them up until you've reached parallel (or as far as you can go). Lower your legs back down to the starting position.
  • This completes one rep.

  • On your mat, lie on your back with your knees bent and feet flat on the floor. Be sure to keep your feet underneath your knees, not in front. Place the dumbbell on top of your lower abdominals (below your belly button and above your hip bones). Hold the dumbbell in place with both hands to prevent it from moving.
  • Raise your hips up to the ceiling, tensing your abs and squeezing your butt as you do. You should be making a long diagonal line with your body, from shoulders to knees.
  • Hold for three seconds, making sure your spine doesn't round and your hips don't sag. Keep your abs and butt muscles engaged.

  • Stand in the center of the hex bar with your feet hip-width apart.
  • Bend at your hips and knees as you grab the handles of the hex bar. Raise your hips up slightly, keeping your back flat, to create tension in the back of your legs (your hamstrings will feel tight).
