Lunges with a jet engine. Switch legs mid-air.

Land with a soft front knee tracking over your toes, not crashing inward.
Lunge jumps take the split squat position and add flight, you explode off both legs, scissor mid-air, and land in the opposite lunge, so every rep is a max-intent quad contraction followed by a single-leg landing to absorb. The glutes drive the takeoff and control the catch, one leg leading at a time. They earn their place as leg power training with zero equipment, and as the finisher that turns a leg day from done to destroyed.
Not if you land properly, soft front knee, tracking over your toes, absorbing down into the next lunge. If your knee crashes inward or the landings are loud, regress to regular reverse lunges and squat jumps until you can land quiet.
Quality expires fast on explosive work, sets of 6 to 10 total jumps with full effort beat sloppy sets of 30. For conditioning finishers, cap sets when your landing form starts to decay.
The split stance means each landing is caught mostly on one lead leg, adding a balance and stability tax on top of the explosive work, and the mid-air switch demands coordination. It is a single-leg power drill dressed up as a burner.
