Lunges vs Split Squats: Differences and Proper Form

Single-leg exercises are some of the most useful, and most avoided, movements in any program. They are hard, they make you wobble, and they burn. They also build strength and muscle in the legs and glutes, expose side-to-side differences, and need very little equipment.

The Three Main Variations

• Split squat: both feet stay planted in a staggered stance and you lower straight down. The most stable and the easiest place to start.
• Lunge: you step forward or backward into the bottom position each rep, then return. More balance and coordination needed.
• Bulgarian split squat: the rear foot rests on a bench behind you. The front leg does almost all the work, which makes it very effective and very demanding.

Split Squat Technique

• Take a long stride so that, at the bottom, both knees are bent around 90 degrees.
• Keep most of your weight on the front foot, through the whole foot rather than just the toes.
• Lower until your back knee nearly touches the floor, then drive up through the front foot.
• A slight forward lean of the torso is normal and puts more work on the glutes. A more upright torso puts more on the quads.

Lunges: Forward or Reverse?

Reverse lunges, where you step back, are usually easier on the knees and easier to balance, because your weight stays over the front foot. Forward lunges demand more braking from the front leg. Walking lunges add a conditioning effect and are great when you have space. If your knees complain, start with reverse lunges and see knee-friendly leg training.

Bulgarian Split Squat Tips

• Find your foot position before you load it: too close and your front heel lifts, too far and your hip stretches uncomfortably.
• Use the rear foot only for balance, not to push.
• Start with body weight, then hold dumbbells at your sides.

Programming

2 to 3 sets of 8 to 12 reps per leg works well. Always start with your weaker side and match the reps on the stronger side. These exercises fit well after a main squat or as the main leg exercise for home training. See unilateral training benefits for why they deserve a place, and bodyweight leg workouts for a no-equipment session.

Expect Soreness at First

Single-leg work creates a lot of muscle soreness when it is new, especially in the glutes. Start with fewer sets than you think you need and build up over a few weeks. More in muscle soreness explained.
