Hip Thruster — the engine that propels the tip indirectly

You do not move the loaded point directly. You feed one input — hip effort (glute torque) — and the linkage carries it: shoulders pinned (pivot), feet planted (base), the hip joint travels an arc, and the load rides that arc up to lockout. The defining twist: resistance is highest at the top (longest moment arm), so constant effort stalls short — you must shape effort over the arc. Hold left-drag up/down on the loaded hip (or hold ↑) to add effort · right-drag / Space+drag to orbit · wheel zooms · the foot-placement slider re-splits knee-drive vs hip-drive.
