Pilates Side Bend: Technique, Muscles Worked and Modifications

How to do the Side Bend

Sit sideways on your mat with your legs bent, placing your top foot flat in front of your bottom ankle. Rest your supporting hand on the mat in line with your hip and rest your top arm on your upper knee.

1. Press firmly into your supporting hand and both feet.
2. Lift your hips off the mat while straightening your legs to come into a side plank position.
3. Reach your top arm overhead to create a lateral arc with your body.
4. Hold this arched position briefly while keeping your shoulder blades stable.
5. Lower your hips slightly toward the mat without resting them down.
6. Lift your hips back up into the high lateral arc.
7. Bend your knees and slowly return your hips to the starting position on the mat.

• Breath. Teachers cue breathing differently for this exercise, but a common pattern is to inhale as you lift your hips into the arc. Exhale as you lower your hips slightly, and inhale to lift back up before exhaling to return to the mat.
• Where you feel it. You should feel strong work in the obliques and quadratus lumborum on the underside of your torso, along with effort in your supporting shoulder and outer hip. You should not feel sharp pain in your wrist or a pinching sensation in your lower back.
• How many. 3 to 5 repetitions on each side

Common mistakes

• Sinking into the shoulder. Push the floor away actively with your supporting hand to engage your shoulder stabilizers.
• Twisting the torso. Keep your chest and hips facing straight ahead rather than letting them roll toward the floor.
• Dropping the head. Keep your neck in line with the rest of your spine as you move into the side bending arc.
• Misaligning the hand. Place your hand slightly further away from your hip during setup so your wrist sits directly under your shoulder when lifted.

Make it easier or harder

Easier

• Perform the movement with your bottom knee resting on the mat for extra support.
• Practice a static side plank without the lateral arc and hip dip.
• Perform the exercise on your forearm instead of a straight arm to reduce wrist strain.

Harder

• Stack your feet completely on top of one another instead of staggering them.
• Hold the top arched position for several extra breath cycles.

Who should be careful

• Side bending under load may need to be limited with osteoporosis or a recent back injury.
• Weight-bearing through the hands can aggravate wrist, hand or shoulder pain. Fists, forearms or a raised surface can reduce the load.
• This is an advanced exercise. Build the strength and control from the simpler versions first, ideally with a qualified teacher watching.

When to see a doctor or physical therapist

• Sharp or shooting pain in your supporting wrist or elbow.
• A pinching sensation in the shoulder joint of your supporting arm.
• Sudden or severe pain in your lower back during the side bend.
• Numbness or tingling traveling down your arm.
