Knees In And Out On A Chair
Knees In And Out On A Chair Exercise Description
Knees In and Out on a Chair is a seated, bodyweight hip-flexion exercise performed on a stable chair. The movement centers on drawing the knees toward the torso and extending the legs away while keeping the trunk braced and the spine neutral. Primary muscles include the hip flexors (iliopsoas and rectus femoris), with assistance from sartorius and tensor fasciae latae; the abdominal wall (rectus abdominis and obliques) works isometrically to stabilize the pelvis and lumbar spine. This drill emphasizes coordinated hip motion without compensatory trunk swinging, promoting precise control of lumbopelvic position throughout the range. It’s a concise way to practice controlled hip flexion and extension using only body weight and a chair.

How To Do The Knees In And Out On A Chair Exercise
‘- Use a sturdy, non-wheeled chair on a flat surface.
– Sit near the front edge; lightly grip the seat beside your hips.
– Set shoulders down and back; keep your neck long and gaze forward.
– Lengthen through the spine and brace your abdominal wall.
– Hinge back a few degrees from the hips while maintaining a neutral spine.
– Bring feet together; extend legs forward with heels lightly touching or hovering just off the floor.
– Initiate by flexing at the hips: pull both knees toward your chest to a comfortable end range.
– Keep the torso angle steady—avoid rounding the lower back or leaning forward.
– Briefly pause to eliminate momentum.
– Reverse by extending the hips and knees to send the legs away without locking the knees.
– Breathe out as the knees come in; breathe in as the legs extend.
– Move in a smooth, controlled manner; if the chair shifts or your spine position changes, reset before continuing.

Knees In And Out On A Chair Beginner Introduction
Knees In and Out on a Chair uses only body weight and a sturdy chair to train controlled leg movement while seated. The action centers on lifting the knees toward the body and then lengthening the legs away, all while the upper body stays steady and tall. Because the chair supports the body, attention shifts to how the hips bend and straighten rather than to balance or complex equipment.
This exercise targets the hip flexors and front of the thighs as they raise and lower the legs, while the abs and side abs work steadily to hold the pelvis and lower back in a stable position. The upper body remains quiet, so any swinging or rocking through the torso becomes easy to notice and refine. As a result, the drill highlights smooth, deliberate motion at the hips with an engaged midsection, offering a compact way to rehearse precise hip bending and straightening in a seated setup.
