Step too short
Step back far enough that the front shin stays fairly vertical at the bottom.
Lunge · Dumbbells
A lunge where you step backward instead of forward, holding dumbbells at your sides. Stepping back is generally easier on the knees and easier to balance than a forward lunge. Good for beginners and anyone building single-leg strength.
The quads and glutes of the front leg do most of the work; a more upright torso biases the quads, a slight forward lean biases the glutes. The adductors and hip stabilizers also work to keep the knee in line.
Step back far enough that the front shin stays fairly vertical at the bottom.
Keep the knee tracking over the middle toes.
Keep most weight on the front leg so it does the work.
Surpass starts the reverse lunge at 8–12 reps with about 2 reps in reserve. As a compound lift it usually belongs early in the session, when you are fresh.
Build to 10-12 reps per leg, then go up one dumbbell size. Once grip limits you, use straps, a barbell, or move to a Bulgarian split squat.
Surpass shows what you lifted last time beside a target for this set, and adjusts it from your reps and RIR. Free on iPhone, no account needed.
These train the same main muscles. Swap when the equipment is busy, something hurts, or progress has stalled for several weeks.
The reverse lunge is easier to balance and usually gentler on the knees. The forward lunge adds a braking demand to the quads. Both work the same muscles.
Both. Staying upright shifts work toward the quads, while leaning forward slightly puts more on the glutes.
