Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Load the sled with appropriate weight (start light if new). Position behind the sled, gripping handles or bar. Lean forward, back straight, core engaged, feet shoulder-width apart. Drive the sled forward with powerful strides, maintaining a steady pace. To pull, attach straps and walk backward or forward, keeping your core tight and movements controlled.
Maintain a strong core to prevent lower back strain. Use consistent strides, avoiding overextension. Start with lighter weights to refine form. Ensure ample, clear space. Incorporate into circuits or as a standalone strength exercise.
