Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Lie on your back with legs extended. Bend knees, bringing the soles of your feet together, allowing knees to fall open. Position heels close to your pelvis. Rest arms alongside your body, palms up, or on your abdomen. Relax and breathe deeply. Hold for 3-5 minutes.
Maintain a flat back. Use cushions under thighs if needed. Relax inner thighs and let gravity deepen the stretch. Breathe deeply to enhance relaxation. Gently bring knees together to exit.
