The angled sled that lets your quads move real weight.
Keep your lower back pinned to the pad. If your hips curl up at the bottom, don't go so deep.
The 45-degree sled angles the load so your quads press against gravity and the plates at the same time, which is why the weight adds up fast on this machine. The tilted path lets you sink into a deep knee bend with your back supported, hitting the quads through a long range while the glutes help drive out of the bottom. It's the classic plate-loaded leg builder for going heavy after squats, or instead of them.
The sled carries the stabilising work and the angle means you're only moving part of the load's effective weight. Don't compare numbers across machines, just beat your own.
As deep as you can while your hips and lower back stay glued to the pad. The moment your hips curl up, that's your depth limit, so set the range there and own it.
Yes. Feet lower on the platform bias the quads with more knee travel, feet higher shift toward the glutes. Shoulder width in the middle is the balanced default.
