How to coach the lunge.

Stand tall with feet hip-width apart, holding dumbbells at your sides or hands free for a bodyweight version. Brace your core, step one foot into a long stride, and lower straight down until the back knee hovers above the floor and the front thigh is about parallel. Keep the torso tall and the front knee tracking over the foot, then drive up through the whole front foot back to standing. The single most important cue is to keep most of the weight on the front foot and lower straight down, not forward.

The lunge is a single-leg compound exercise that trains the quadriceps and glutes as the prime movers, with the hamstrings and adductors assisting hip extension and stabilising the front knee. Because you balance on one leg, the core and spinal erectors work hard to keep the torso tall and square, and the calves and ankle stabilisers control balance over the front foot. Training one leg at a time also exposes and helps even out left-to-right differences in strength.

Neither is simply better - they do different jobs, and most programs use both. The squat lets a client load both legs heavily and build raw lower-body strength, while the lunge trains each leg on its own, challenges balance, and is gentler on the lower back. A common approach is to anchor a session with a bilateral lift like the squat, then use lunges as a single-leg accessory to add volume and balance out the legs. The right mix depends on the client's goal, equipment, and history.

It depends on the goal and the variation. As a single-leg accessory, a common home base is 2 to 4 sets of about 8 to 12 reps per leg, with bodyweight or moderate dumbbells. Lower reps with heavier load lean toward strength, while higher reps suit endurance and conditioning. Because each rep is a balance challenge, build volume gradually and stop a set once form starts to drift rather than grinding out sloppy reps just to hit a number.

Start with the bodyweight lunge to groove the pattern, the depth, and the balance, then add dumbbells once the movement looks clean and controlled. Bodyweight lunges are a great warm-up, a conditioning tool, and the right starting point for most beginners; dumbbell lunges let you load the legs harder for strength and muscle once balance is solid. The progression is to own the bodyweight version first, then add the smallest load that still lets you keep good form.

The lunge is a fundamental movement most beginners can learn, but form is individual and load should start light - usually bodyweight first. Begin with a stationary lunge, add a hand on a rail if balance is shaky, and progress to walking or weighted versions only once the pattern is clean. Form varies with each person's build, mobility, and injury history, so the gold standard is a qualified coach watching the movement and giving a form check. This is technique education, not medical advice - clients with pain or a relevant history should clear it with a qualified professional first.
