Lying Knee Roll Over Stretch is a beginner bodyweight exercise for the primary: obliques secondary: lower back.
Lying on your back with knees bent, you let both knees fall to one side while keeping your shoulders flat on the floor to stretch the obliques and lower back. Alternate sides and breathe deeply into the stretch rather than forcing the range.
Hold the lying knee roll over stretch for 2 to 3 sets of 30 to 60 seconds per side at the end of a workout, after deadlifts or squats, or as part of a morning or evening mobility routine. It is a gentle release for the lower back and obliques rather than a strength exercise.
Lie on a mat with the arms out as anchors, keep the knees together and let the drop be driven by gravity and relaxation. There is no load to progress; instead add a few seconds per session, try straightening the top leg for more hamstring and outer hip stretch, or hold the top knee down lightly with the hand. The most common fault is the opposite shoulder peeling off the floor; fix it by reducing the knee drop until both shoulder blades stay down.
It stretches the obliques, the lumbar erectors and the glute and outer hip of the top leg. The chest and front of the shoulder also open as the arms stay out and the shoulders press down.
For general stiffness and muscle tightness it usually feels relieving and is safe. If you have a disc injury or pain that shoots down the leg, keep the range small or check with a physiotherapist first.
Hold each side for 30 to 60 seconds, breathing slowly, and repeat two or three times. Longer, relaxed holds work better than short forced ones for releasing the back.
