Boxer's Engine

intermediate45 min~550 kcalShouldersCoreChestCalves

A 45-minute boxing conditioning session that builds the engine rather than the technique. Five rounds of jump rope open it, shadow boxing keeps the shoulders working through fatigue, explosive push-ups and medicine-ball rotational throws train punching power, and Russian twists plus fast feet finish the core and footwork.
