Open the hips and wake up the glutes in circles.
Keep your hips level and core tight so you move the leg, not your whole torso.
Drawing circles with a lifted knee moves the hip through abduction and rotation in one continuous sweep, forcing the abductors along the outside of your hip to control positions that straight up-and-down raises never visit. One side works through the arc while the rest of you holds the all-fours position dead still. It is mobility and strength rolled into a single pre-leg-day drill.
The standard version lifts and lowers in one plane, circles add rotation and demand control through the entire arc. Use circles when your hips feel stiff and standard hydrants when you want straightforward strength reps.
As big as you can draw while your hips and lower back stay perfectly level. Small controlled circles that grow over weeks beat wild loops powered by a rocking torso.
The abductors are small muscles doing unfamiliar continuous work, so they fatigue fast. That deep burn means you found the target, finish the set in both directions before switching legs.
