Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Stand with feet shoulder-width apart, holding a taut resistance band with both hands in front of your thighs, arms straight. Slowly raise arms overhead, keeping them straight and maintaining band tension, until the band reaches behind your back (as far as mobility allows). Reverse to starting position. Control the movement and maintain band tension throughout.
Use a band length and resistance allowing a full range of motion. Engage your core for stability. Reduce range or resistance if you feel discomfort. Prioritize controlled movements for shoulder mobility.
