Hands locked, low body angle, just drive.
Stay low with a long body line, standing tall kills your leg drive.
Driving a sled from a low forward lean is leg drive in its purest form, quads extending the knee on every stride while the glutes and hamstrings push the hips through. With arms locked on the posts, there is nothing to lift, swing or lower, just force into the ground for the whole distance. It earns its place as brutal conditioning that doubles as leg work, with no lowering phase and no technique ceiling to slow you down.
Heavy pushes build strength, slow grinding steps with maximum leg drive. Light and fast pushes are conditioning, closer to sprint work. Both belong, just not in the same set.
Locked. Bent arms turn into shock absorbers that leak your leg drive. Stiff arms, low body, long line from head to heel.
An upright torso points your force down instead of forward. Stay low with a long body line so every step drives the sled ahead rather than into the floor.
