Side-Lying Leg Work on the Reformer
This exercise is a beautiful combination of hip mobility, lower-body strength and core stability. Working against the spring resistance challenges the muscles around the hip while the trunk has to stay controlled and stable.
What is it good for?
• Strengthening the glutes and hip stabilisers
• Improving hip mobility and control
• Challenging lateral core stability
• Developing coordination and body awareness
• Teaching the body to move the leg without losing pelvic alignment
What to pay attention to:
• Keep the pelvis stable — avoid rolling forward or backward
• Keep the supporting side of the body active
• Move from the hip rather than swinging the leg
• Maintain a long spine and relaxed shoulders
• Control the spring both out and back in
• Choose a resistance that allows you to keep precise technique throughout the movement
Quality over range. A smaller, controlled movement with a stable pelvis is much more effective than chasing a bigger range with compensation.
