The primary difference between lunges vs squats is that a squat is a bilateral exercise because both of your legs are performing the exact same movement pattern in tandem side-by-side. On the other hand, a lunge is a unilateral exercise. Your feet assume a staggered stance, such that one leg is in front of the other.

Lunges are a unilateral exercise, meaning you work one side at a time. Basic squats are bilateral, working both sides at once. Lunges increase stability and help with muscular imbalances on different sides of the body. Squats are excellent for building lower body strength and core stability.

Squats and lunges are considered compound, or multi-joint, exercises. They engage the muscles of the glutes, thighs, and calves, as well as the core and lower back. Additionally, they involve flexing the hips, knees, and ankles. When performing variations with dumbbells or kettlebells, you also engage the muscles and joints of the arms.
