Rear Shift Lunge From Deficit is an intermediate bodyweight exercise for the primary: glutes secondary: hamstrings. Most lifters train it for 3 to 4 sets of 8 to 12 reps.
Stepping back into a reverse lunge from an elevated platform increases the range of motion at the hip and knee compared to a lunge done on flat ground. The extra depth puts more emphasis on the glutes and hamstrings of the front leg.
Program the rear shift lunge from deficit as a second or third lower body exercise after squats or hinges. Use 3 to 4 sets of 8 to 12 reps per leg with 60 to 90 seconds rest; it builds glute and hamstring strength through a longer range of motion than a flat lunge.
Start with bodyweight on a 10 cm platform and progress to a 20 cm box, then hold 8 to 12 kg dumbbells, working up to 15 to 25 kg per hand. Keep the front shin close to vertical and the torso tall. The most common fault is pushing off the back foot, so touch the rear toe lightly and feel the front glute drive you up.
It works the glutes and hamstrings of the front leg more than a standard lunge because the deeper hip flexion increases the stretch, with the quads and adductors assisting. The core works to keep the torso tall.
Ten to 20 cm is enough for most people. Higher platforms increase the range but make balance harder and can round the back.
The deficit version increases the range and glute stretch, making it harder with the same load. Use the regular version to learn the movement and the deficit version to progress.
Usually yes because the reverse step keeps the front shin more vertical than a forward lunge. Keep the front knee tracking over the toes and step straight back, not inward.
