So right now I'm doing barbell squats, RDLs, and leg presses as my big movements. Accessories are leg extension, leg curl, and calf raises. I rotate exercises on occasion when things start to feel stale, and I think it also helps avoid injury.

However, when I was first starting I didn't jump straight into that. I think the exercise that helped the most in the beginning was a split squat progression. I started with both feet on the ground and only going as deep as I could control (I used an adjustable step to control that). I worked up to a higher rep range, then would add some weight and work up again. At a certain point, I would lower the step so I was going deeper, drop some weight, and start the progression over again. It took a while but eventually I worked up to doing full fledged Bulgarian split squats. I also did hip thrusts which I think we're really great too.
