Why sandbags instead of a barbell?
The shifting load forces more trunk stabilisation and is more forgiving to drop, which makes it safer at high fatigue.
What Is a Sandbag Lunge?
Walking lunges with a sandbag carried across the shoulders, over a set distance.
A sandbag lunge is a walking lunge performed with a sandbag resting across the upper back and shoulders. Unlike a barbell, a sandbag shifts and settles as you move, which forces the torso to work constantly to stay upright.
In race formats it is performed over a set distance — commonly 100 m — rather than for reps, and it usually lands near the end of the event when legs are already heavily fatigued.
Because the load sits high on the body, this station is as much a trunk and breathing challenge as it is a leg exercise.
Muscles worked
- Quadriceps and glutes — the main load
- Hamstrings and adductors stabilising each step
- Upper back and traps supporting the bag
- Core and breathing muscles under a compressive load
How it is judged
- The trailing knee must touch the floor on every step.
- The front knee must fully extend before the next step begins.
- The bag must stay on the shoulders or upper back; carrying it in the arms is not permitted.
- Competition weights are commonly 20 kg for men's open and 10 kg for women's open over 100 m.
Common questions
What if I can't get my knee to the floor?
Mobility and load are the usual causes. Reduced range with a lighter bag is normal scaling until the range improves.

Knowing the definition is one thing. Pacing it, transitioning between stations and holding form when you're cooked is what our coaches teach in our workshops and race simulations at Fit 4 Life Club, Port Coquitlam.
