Why Reformer Pilates Specifically Strengthens Your Upper Body

Your upper body – including your core, shoulders, back, chest, and arms – plays a vital role in your posture, mobility, and daily physical resilience. Especially for those who sit for long periods or experience repetitive strain in daily life, shoulder and neck tension or back pain are all too familiar. This is exactly where Reformer Pilates comes in: with targeted exercises on the Reformer, you can strengthen, mobilize, and relieve your upper body – simultaneously and holistically.

Benefits of Upper Body Training on the Pilates Reformer

Reformer Pilates training for the upper body is highly effective because it is precise, gentle on the joints, and offers a full-body workout. The guided movements using ropes and springs not only promote muscle building but also improve coordination between your core, arms, and shoulders – for better stability and posture. Here are the benefits of upper body training with the Pilates Reformer:

Targeted strengthening and improved posture
Core activation is included in every exercise
Enhanced mobilization and flexibility
Individually adjustable thanks to spring tension

Pilates expert Greta explains: "Reformer Pilates effectively strengthens the upper body – without overstraining. The shoulders and back especially benefit from this precise, gentle strengthening."

Which muscles are trained during an upper body Reformer Pilates workout?

The upper body Reformer Pilates workout is specifically designed to activate multiple muscle groups simultaneously – deeply, functionally, and gently on the joints. Through the guided pulling and pushing movements on the Reformer, you not only strengthen isolated muscles, but also improve how they work together in everyday life. These muscle groups are particularly targeted:

Shoulders and shoulder girdle:
Exercises like Chest Expansion or Arm Circles promote stability and mobility in your shoulders, helping to relieve tension.
Upper arms:
During bicep curls, as well as all pulling and pushing movements with the straps, your arm flexors and extensors work together to target and tone for defined, lean arms.
Upper and middle back:
Especially with pulling straps or reverse chest expansions, you'll strengthen your back extensors and interscapular muscles – noticeably improving your posture.
Chest muscles:
Pushing or opening movements are especially effective at activating the chest muscles, helping to improve your posture and promote better muscle balance.
Deep core and trunk muscles:
Since you need core stability for all exercises, your core remains constantly engaged—especially during rotations or diagonal movements like the side kneeling rotation.

Reformer Pilates Exercises for the Upper Body

Our Reformer Pilates expert Greta guides you through our 10-minute workout video, targeting your core, back, shoulders, and arms.

1. Single Leg Extension

➡️ 2 red resistance bands

➡️ 8–10 reps (alternating legs)

For your first core activation, start by lying on your back with your legs raised at a 90-degree angle. "As you exhale, extend one leg diagonally forward. At the same time, consciously pull your belly button in toward your spine," explains expert Greta. She also emphasizes: "Only extend your leg as far as you can maintain your core tension." Then, bring your leg back to the starting position.

2. Arm Circles

➡️ 2 red resistance bands

➡️ 5 repetitions

In the same position, grab the short loops and bring your arms straight up over your shoulders. "This exercise combines core strengthening with shoulder joint mobilization," says Greta. "To do this, lower your arms from the shoulder joint down next to your body while exhaling. Then rotate outward to bring them back to the starting position in a circle while inhaling."

3. Curl ups: Single Leg Extension

➡️ 2 red resistance bands

➡️ 4 repetitions (2 per side)

“Lift your upper body as you exhale. At the same time, push both your arms and one leg forward,” the Pilates instructor directs. “Focus on keeping a rounded back and pulling your ribs toward your pelvis.” Inhale as you lower yourself back down in a controlled motion. Repeat, alternating sides.

4. Chest Expansion

➡️ 2 red rubber bands

➡️ 5 repetitions

Come into a kneeling position on your heels on your Pilates Reformer, facing the ropes, and grab these ropes above the carabiner. "As you inhale, pull the ropes so that your arms pull alongside, or maybe even behind, your pelvis. In doing so, you activate your shoulder blades, and your core is engaged," Greta explains. "Keep your upper body upright over your pelvis. Your torso should not lean forward."

5. Reverse Chest Expansion

➡️ 2 red resistance bands

➡️ 5 repetitions

This time, sit on your heels facing forward. Place your hands back into the loops. "For this core, chest, and shoulder exercise, bring your arms forward to shoulder height as you exhale. Then, open them up and lower them back down next to your pelvis. In addition to strengthening, this also mobilizes your shoulders."

6. Bicep Curl

➡️ 2 red resistance bands

➡️ 5 repetitions

"This Reformer Pilates exercise not only targets your biceps, but also engages your core at the same time," says Greta. You start seated with your feet on the shoulder pads, your back slightly leaned back, holding the loops in your hands, and your arms extended forward so that your elbows are at shoulder height. "As you exhale, bend your elbows for a bicep curl. As you inhale, extend your arms back out."

7. Side Kneeling Rotation

➡️ 1 red + 1 yellow resistance band

➡️ 5 repetitions per side

“Important: When in a high kneeling position, make sure to keep the back of your legs active,” emphasizes expert Greta. Alternatively, you can also do the exercise while kneeling. Sit sideways on your Reformer, take the loops in both hands, and bring your hands together in front of your chest. “The movement comes from the waist, and you rotate to the side toward the footbar as you exhale. The focus is on the obliques and your core stability.” Switch sides after 5 repetitions.
