Reverse Lunge

View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start: standing tall, feet hip-width, weight even, arms relaxed at sides, trunk upright with ribs stacked over pelvis
End: split stance with one foot stepped behind, back knee lowered toward the floor and front knee bent near 90°, front shin near-vertical with knee tracking over second toe, trunk still upright
Range of Motion: hip and knee flexion 0→~90° in the stepping-back stance; return to full hip/knee extension in standing

How to Perform

From standing, step one foot backward and lower the back knee toward the floor until both knees reach roughly 90 degrees, keeping the trunk upright and weight centered over the front foot. Drive through the front foot to return to standing, then repeat on the same side or alternate legs. Compared with a forward lunge, the stepping-back pattern keeps the front shin more vertical, which many patients with anterior knee pain tolerate better.

Coaching Cues

1
Drop the back knee straight down toward the floor, like an elevator, not forward.
(external)
2
Push the floor away through the whole front foot to stand back up.

3
Keep the front shin close to vertical with the knee tracking over the second toe.

4
Stay tall through the chest with ribs stacked over the pelvis; avoid collapsing forward.

Evidence-Based Dosing & EMG Data

Recommended Dosing

Consistent with general resistance-training guidelines: 2-4 sets of 8-12 repetitions per leg, 2-3 sessions per week, progressing load or depth as tolerated. For hypertrophy or strength emphasis, adjust load so the last 2-3 reps are challenging. No reverse-lunge-specific dosing trials exist; this is extrapolated from general lower-limb resistance training evidence.

EMG Activation Data

Lunge-family exercises show high activation of the quadriceps (vastus lateralis and medialis) and gluteus maximus of the lead leg, with moderate hamstring and gluteus medius activity for knee and pelvic stabilization. Biomechanical comparisons of lunge variants indicate that stepping backward keeps the lead tibia more vertical and reduces anterior translation demand and patellofemoral joint stress relative to the forward lunge, shifting relative emphasis slightly toward the hip extensors. Trunk lean forward increases gluteal and hamstring contribution; an upright trunk biases the quadriceps. Most published EMG work examines forward or walking lunges, so reverse-lunge-specific activation data are sparse and largely inferred from the broader lunge literature.

Muscles Involved (12)

Primary Movers

Quadriceps Femoris— Lead-leg knee extensors control descent eccentrically and drive the ascent.

Gluteus Maximus— Lead-leg hip extension during the ascent; loading increases with forward trunk lean or added weight.

Secondary Movers

Hamstrings (Group)— Assist lead-leg hip extension and co-contract to stabilize the knee.

Adductor Magnus— Posterior fibers assist lead-leg hip extension from the deep split position.

Stabilizers

Gluteus Medius— Controls frontal-plane pelvic drop and lead-leg femoral adduction/internal rotation.

Gluteus Minimus— Works with gluteus medius for lateral hip stability on the stance leg.

Erector Spinae Group— Maintains an upright, neutral trunk throughout the split position.

Transversus Abdominis— Anticipatory trunk stiffness during the single-leg-dominant transition.

Gastrocnemius— Acts largely isometrically to control the lead tibia/shank angle over the foot; trailing leg only lightly touches down, so push-off contribution is minimal.

Soleus— Stabilizes the lead ankle and shank angle in stance.

Lengthened / Stretched

Iliopsoas— Trail-leg hip flexors are placed on stretch at the bottom position as the trailing hip extends, especially with a posterior pelvic tilt.

Rectus Femoris— On the trailing leg, combined hip extension and knee flexion lengthens the two-joint rectus femoris; on the lead leg it works within the quadriceps group.

Easier Variations ↓

Supported reverse lunge

Hold a countertop, dowel, or suspension trainer for balance assistance while performing the same stepping pattern.

Partial-depth reverse lunge

Lower only through a comfortable partial range, or tap the back knee to a raised pad/box to limit depth and load.

Harder Variations ↑

Loaded reverse lunge

Add a goblet-held kettlebell or dumbbells at the sides; progress load while maintaining trunk and knee control.

Deficit reverse lunge

Stand on a low step or plate so the back foot lowers below the front-foot level, increasing hip flexion range and gluteal demand.
