Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Anchor a resistance band firmly around a stable rack or pole. Stand facing away from the anchor point, holding the handles/ends with both hands and extending your arms overhead toward the anchor. Walk forward to create initial resistance in the band. Set your feet shoulder-width apart, lock your core, and lean your upper body slightly forward from the hips. Flex at the elbows, bringing the band down behind your neck until your elbows form a right angle (90°). Contract your triceps to extend your arms fully, returning to the start position to finish the rep. Perform the target number of repetitions. Keep your elbows tucked in throughout the set and avoid using momentum or leaning your torso to move the weight.
