For a quad-dominant leg workout, choose a single-leg supported movement like a split squat or Bulgarian split squat as your main lift since you can use a heavier load for those. Then use a single-leg unsupported hip-dominant movement like single-leg RDLs for higher reps. You should still use the heaviest load on those that you're capable of with good technique.
For a hip-dominant leg day, choose whatever hip movement you can load. Can you do a pull-through? Or maybe use a hip-dominant step-up or single-leg stability ball hip extension. Then follow it with a single-leg unsupported quad-dominant movement, like your best
progression toward a pistol, for slightly higher reps.
No calf raises or leg extensions though.
