Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Secure a resistance band at waist height. Stand facing away, holding each end. Step forward to create tension, then raise arms overhead with bent elbows close to your head. Extend arms fully, squeezing triceps. Slowly return, controlling the band. Repeat.
Keep elbows near your head. Slightly bend knees for stability. Use slow, controlled movements. Maintain a tight core and straight back. Adjust band tension for challenge. Exhale on extension, inhale on return.
