Setup
- Position a barbell across your upper traps and unrack it, standing with feet hip-width apart.
- Ensure you have clear space approximately 3-4 feet both in front of and behind you.
- Engage your core and pull your shoulder blades together to create a stable shelf for the bar.
How to do it
- Step forward with one leg into a lunge, inhaling as you lower your hips until both knees are at 90-degree angles.
- Exhale and drive forcefully off the front foot to swing that same leg directly into a reverse lunge without touching the floor in the center.
- Inhale as you lower into the reverse lunge, then exhale and drive through the stationary foot to return to the starting standing position.
- Complete the full forward-backward sequence on one leg before switching sides or alternating.
Form checklist
- Keep your torso upright throughout the transition to prevent the barbell from shifting forward.
- Maintain a 'tracks, not a tightrope' stance by keeping feet hip-width apart during the lunges.
- Ensure the knee of the lead leg tracks in line with your toes, avoiding any inward collapse.
- Keep your core braced tightly to stabilize the spine against the moving weight.
Pro tips
- Focus on the stationary leg as an anchor; it should remain rooted while the moving leg acts like a pendulum.
- To maximize stability, fix your gaze on a stationary point on the floor about 5-10 feet in front of you.
- Minimize the 'tap' in the middle transition to keep constant tension on the stabilizing glute and quad.
Make it harder
- Add a 2-second pause at the bottom of both the forward and backward phases of the movement.
- Increase the speed of the transition through the center to challenge your reactive stability and balance.
Frequently asked
- What muscles does the barbell forward backward lunge work?
- The barbell forward backward lunge primarily targets the calves, glutes, hamstrings, and quadriceps, and also works the adductors and hip flexors as secondary muscles.
- What equipment do you need for the barbell forward backward lunge?
- The barbell forward backward lunge uses barbell and weight plate.
- Is the barbell forward backward lunge good for beginners?
- The barbell forward backward lunge is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
