The Bulgarian split squat is the bridge between the regular full squat and true single-leg strength. You stand a couple of feet in front of a bench, rest the top of one foot on it behind you, and squat down on the front leg. Because your rear leg is supported but not really pushing, the front leg ends up doing around 80% of the work. That's close enough to a single-leg squat that you can build the strength needed for pistol squats without needing their balance demands yet.
Expect these to humble you. Most people who can rep out 20 bodyweight squats will gas out at 8 Bulgarians per side. That's the point. You're finally loading one leg at a time.
How to do it
Stand about a leg's length in front of a bench, chair, or couch. Place the top of one foot behind you on the bench. Your front foot should be far enough ahead that your shin stays roughly vertical at the bottom of the squat. Squat down on the front leg until your back knee lightly kisses the floor, then drive through the whole front foot to stand back up.
