Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Lie on your side, legs stacked and aligned. Support your head and hips. Engage your core and slowly lift the top leg straight up until you feel tension in your outer hip. Pause, then lower with control. Repeat, then switch sides.
Maintain core engagement and hip stability. Control the movement, avoiding rotation. Limit the lift to feel glute tension without compromising form. Breathe steadily, exhaling on the lift, inhaling on the lower. Add a resistance band for increased difficulty.
MuscleTrain is actively being built. If something looks broken, or you have a suggestion, let us know — it really helps shape the app.
