Lunge vs Split Squat

Is it a lunge or a split squat?

Both exercises look similar and are great for developing your legs, however there are a couple of differences.

Both exercises see one leg forward, one back and you lowering your hips until your knees are bent to right angles…The difference however is to do with the concentric phase (straightening the legs.

Lunges: place equal pressure on the heel of the front foot and ball of the rear foot
Split Squats: the rear leg rests whilst the lead leg does all of the work
