Sled (Prowler)
A weighted apparatus pushed or pulled for conditioning and strength.
Sleds and prowlers are pushed, pulled, or dragged for conditioning and leg strength. They provide intense lower body work with minimal eccentric stress, meaning less soreness and faster recovery. Sled work is excellent for athletes, conditioning, and those wanting leg work without heavy squatting.
Why a sled is different
Pushing or dragging a loaded sled is almost purely concentric: the muscles shorten to produce force and never lengthen under load. Because eccentric loading is what drives most muscle damage and soreness, sled work produces a large conditioning and strength stimulus with unusually little to recover from. That combination is rare and is the main reason it has a place in almost every athletic programme.
How to use it
Heavy, short pushes build lower-body drive and behave like a strength exercise. Lighter, longer drags are conditioning that does not interfere much with the next lifting session. Backward drags load the quadriceps hard and are widely used as knee-friendly work when squatting is uncomfortable. It also fits well at the end of a leg session or on an otherwise easy day, precisely because the recovery cost is low.
Common mistakes
Loading it so heavily that it becomes a slow grind, which loses the speed quality that makes sled work useful for athletes. Using it as a substitute for a genuine hinge or squat pattern, which it is not — there is no eccentric, and the eccentric is a substantial part of what builds muscle. And running it on a surface that makes the load unpredictable, so session-to-session progression is impossible to track.
