This Pilates exercise releases the hip flexors, which pull on the lower back. The hip flexors shorten when we sit.
Targets: The hip flexors, obliques, quads
How to
1. Start in a high kneeling position. Take one leg forward into a lunge and press hips forward until you feel a stretch through the front of the thigh and hip
2. Reach up to the ceiling and side bend towards the ring, pressing it down. You should feel a stretch through the side of the body
Tip: For more of a stretch, take the foot farther away
Reps: Hold for 30 seconds each side, breathing throughout
