The lunge is a fundamental lower-body strength exercise that primarily targets the gluteus maximus and quadriceps, with the adductor magnus and soleus providing significant assistance. Performed with body weight, it trains each leg independently, making it effective for building lower-body strength, improving balance, and correcting side-to-side muscle imbalances.

How to do the Lunge

  1. 1Stand tall with your feet hip-width apart and your arms at your sides or hands on your hips.
  2. 2Brace your core and keep your chest upright as you take a controlled step forward with one foot, landing with your heel first.
  3. 3Lower your back knee toward the floor by bending both knees to roughly 90°, keeping your front shin as vertical as possible.
  4. 4Ensure your front knee tracks over your second toe and does not cave inward or drift far past your toes.
  5. 5Stop when your back knee is 1–2 inches above the floor, maintaining an upright torso throughout.
  6. 6Press through the heel and midfoot of your front foot to drive yourself back up to the starting position.
  7. 7Bring your feet together, then repeat the movement on the opposite leg for one complete rep.
  8. 8Continue alternating legs for the desired number of repetitions.

Form tips

  • Keep your torso upright and your gaze forward throughout the movement — leaning excessively forward shifts load away from the glutes and quadriceps.
  • Engage your core before each step to stabilize your pelvis and protect your lower back.
  • Control the descent rather than dropping into the lunge; the eccentric phase builds strength and reduces joint stress.
  • Push through your entire front foot on the way up, not just the toes, to fully recruit the gluteus maximus.
  • Start with a shorter stride length if you feel unstable, then gradually increase it as your balance and hip mobility improve.

Common mistakes

  • Letting the front knee cave inward, which places excessive stress on the knee joint and reduces glute activation.
  • Allowing the front knee to travel far past the toes, which overloads the patellar tendon and shifts the emphasis away from the glutes.
  • Leaning the torso forward, which reduces quadriceps and gluteus maximus engagement and places unnecessary load on the lower back.
  • Taking too short a stride so the front shin angles sharply forward, limiting the range of motion and reducing gluteus maximus involvement.
  • Rushing through the lowering phase, which reduces muscle tension and increases the risk of losing balance or control.

Frequently asked questions

What muscles does the lunge work?

The lunge primarily works the gluteus maximus and quadriceps. The adductor magnus and soleus act as synergists, assisting with hip extension and ankle stability throughout the movement.

Should my front knee go past my toes during a lunge?

A slight forward travel of the knee past the toes is normal, but excessive forward drift increases stress on the patellar tendon. Focus on keeping your front shin as vertical as possible and driving through your heel on the way up.

What is the difference between a forward lunge and a reverse lunge?

In a forward lunge you step forward from a standing position; in a reverse lunge you step backward. The reverse lunge places less shear force on the front knee and is often easier to control for beginners or those with knee discomfort.

How many reps should I do for lunges?

For strength, 3–4 sets of 6–10 reps per leg works well. For muscular endurance or general conditioning, 3 sets of 12–20 reps per leg is a common approach.

Why do I feel lunges more in my front quad than my glute?

This usually means your stride is too short or your torso is leaning forward. Take a longer step so your front thigh reaches parallel to the floor, keep your chest tall, and consciously drive through your heel to shift more work onto the gluteus maximus.
