Lunges: walking, reverse and forward lunges done right

Lunges are a single leg exercise where you take a long step, lower your back knee towards the floor and push back up through your front foot. They train the quads and glutes one leg at a time, along with the adductors and hamstrings, and the direction you step (forward, backwards, walking or to the side) changes how hard they are on the knees and which muscles work most.

How you lunge moves the work around. A short step with an upright torso keeps more of the load on the quads. A longer step with a slight forward lean puts more on the glutes. That makes lunges useful both in a quad focused leg workout and in a plan built from glute exercises or glute exercises with dumbbells.

Reverse lunges

Stepping back means the front foot stays planted and you lower into the lunge instead of braking a step forward. Most people find this easier on the knees and easier to balance, which makes reverse lunges the best place to start. A slight forward lean of the torso brings in more glutes.

Forward lunges

You step forward and the front leg has to stop your body and then push it back. That braking makes the forward lunge more demanding for the quads and the knee. Use it when reverse lunges feel easy and your knees are happy.

Walking lunges

Instead of pushing back, you drive through the front foot and bring the back leg forward into the next step. Walking lunges with dumbbells are a hard leg exercise with a real conditioning effect, because you cannot rest between reps. You need a clear lane of 10 to 20 metres, or turn around halfway.

Lateral lunges

Step wide to one side, sit back into that hip with the knee over the foot, and keep the other leg straight. Lateral lunges train the adductors and glutes in a direction most leg exercises ignore. Use bodyweight or a light goblet hold.

How to do a reverse lunge

  1. Stand tallFeet hip width apart, weights at your sides if you use them. Brace your core.
  2. Step backTake a long step back with one foot and land on the ball of that foot. Keep your feet about hip width apart side to side, like standing on train tracks, not a tightrope.
  3. Lower straight downDrop your back knee until it is just above the floor. The front shin can lean forward a little; that is normal. Most of your weight stays on the front foot.
  4. Drive back upPush through the whole front foot, mainly the heel and midfoot, and bring the back foot forward to the start.
  5. Switch or repeatAlternate legs, or do all reps on one side before switching. One side at a time is easier to keep steady and easier to count.

Balance tips for lunges

Wobbling is the most common complaint with lunges. It is almost always a stance problem, not a strength problem.

  • Widen the tracks. Feet in one line make balance hard. Keep them hip width apart side to side.
  • Look at a fixed point on the floor a few metres ahead.
  • Slow the lowering. Two seconds down gives you time to stay centred.
  • Hold onto something. A rack or wall with one hand while you learn the movement is fine, and you can hold one dumbbell on the opposite side.
  • Start with split squats. Keeping the feet planted removes the stepping, which is where most people lose balance.

Common lunge mistakes

  • Steps that are too short. The front heel lifts and the knee takes all the load. Lengthen the step.
  • Front knee caving inwards. Keep it pointing over your middle toes. Lighter weights help.
  • Slamming the back knee. Stop just above the floor or use a pad.
  • Pushing off the back leg. The front leg should do most of the work. The back foot is mostly for balance.
  • Leaning far forward with a rounded back. A slight lean is fine; collapsing over the front leg is not.
Knee pain: switch to reverse lunges or split squats, shorten the depth and lower the load. If pain stays, see a physiotherapist before you continue.

Weighted lunges: dumbbell, barbell and more

  • Dumbbell lunges: a dumbbell in each hand. The easiest way to load lunges, and grip often limits you before the legs do.
  • Goblet lunge: one dumbbell or kettlebell held at the chest. Good for the upright, quad focused style.
  • Barbell lunge: bar on the back as in a squat. Heavier, but balance matters more, so build up from dumbbells first.
  • Deficit reverse lunge: front foot on a low step for a deeper range and more glute work.
  • Jumping lunges: switch legs in the air. A bodyweight conditioning drill, not a strength exercise.

The Bulgarian split squat is the next step for loading one leg hard, with the back foot raised on a bench. For a full plan without machines, see the dumbbell leg workout.

Sets and reps for lunges

Put lunges after your main squat or hinge, once or twice a week. They fit on the lower days of an upper lower split and at the end of a full body workout.

How to progress lunges

Start with bodyweight and add reps until you can do about 12 to 15 clean reps per leg. Then pick up dumbbells and work back up from 8. Dumbbells usually go up in 2 kg (about 5 lb) steps, which is a big jump for one leg, so add reps before load. The full system is in progressive overload.

Lunge alternatives

  • Split squat: the same position with no stepping, easier to balance.
  • Step-up: step onto a box or bench, low impact for the knees.
  • Bulgarian split squat: back foot on a bench, harder and more glute heavy.
  • Goblet squat: both legs, simple and quad heavy. See the goblet squat guide.
  • Leg press, one leg at a time: a machine option with no balance demand.

Questions people ask

What muscles do lunges work?
Mainly the quads and glutes. The adductors and hamstrings help, and the glute medius, calves and core keep you balanced.
Are reverse lunges better than forward lunges?
For most people reverse lunges are easier on the knees and easier to balance, so they are a better starting point. Forward lunges demand more from the quads because the front leg has to brake the step.
Do lunges work the glutes?
Yes. A longer step and a slight forward lean of the torso put more of the work on the glutes.
Why do I lose balance doing lunges?
Usually your feet are in one line. Keep them hip width apart side to side, slow down, and hold onto something while you learn.
How many lunges should I do?
For strength and muscle, 2 to 4 sets of 6 to 12 reps per leg is a good rule of thumb. Walking lunges for conditioning can be 20 to 30 steps per set.
