No equipment and a simple pattern make this the entry point to the entire lunge family: step out, lower until the front thigh is parallel, push back. Own 10 to 15 clean reps per leg with a tall torso before adding dumbbells, because a wobbly knee path only gets worse under load.
How to do the Forward Lunge
- Stand with your feet hip-width apart and hands on your hips.
- Take a big step forward with your right foot, lowering your body into a lunge position.
- Bend your right knee to about 90 degrees, keeping your knee aligned with your ankle.
- Push off with your right foot and return to the starting position.
- Repeat with your left leg, alternating sides for the desired number of repetitions.
Tip: Keep most of the weight in the front foot and think of pushing the floor away rather than standing up.
Muscles worked
Primary
Glutes · Legs
The glute of the front leg extends the hip, and leaning the torso forward slightly with a longer stride shifts more work onto it.
Secondary
- Quads — The front quad controls the descent and drives you back up, and it takes an especially heavy load on split squats where the stance is fixed.
- Hamstrings — The hamstrings of the front leg assist the glutes in hip extension and control the knee on the way down.
- Calves
Common mistakes
- Front knee caving inward — the knee should track over the second toe; if it drops in, widen the stance slightly and push the knee out.
- Stepping too short — a short stride pushes the knee far past the toes and shifts everything onto the quad and knee; lengthen the step so the shin stays fairly upright.
- Leaning forward and rounding — keep the torso tall and the chest up, and let the back knee drop straight down rather than reaching forward.
- Pushing off the back foot — drive back up through the front heel; the back leg is just there for balance.
Where it fits in a workout
Lunges and split squats go after squats or deadlifts as the main single leg movement, or first on a lighter day. Superset them with a Romanian deadlift for a complete lower body pair.
