Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Lie on your side, aligning your body. Bend your top leg and pull your ankle/foot towards your glutes with the hand on the same side. Gently stretch the front of your thigh. Hold for 20-30 seconds, breathing steadily. Release and repeat on the other side.
Keep hips stacked and maintain a straight line from head to tailbone. Use a strap if needed. Avoid forcing the stretch; it should be gentle. Best performed post-workout.
