HYROX Sandbag Lunges Technique: Bag, Depth and Cadence

By Threshold·Published Oct 2026

Good HYROX sandbag lunges technique is about consistency, not speed. Keep the bag high across the shoulders, chest up, and touch the back knee to the floor on every rep. Find a cadence in the first few meters and hold it for the full 100 m. Most lost time comes from no-reps and from stopping to re-set a slipping bag. Bags run from 10 kg to 30 kg by division.

Where the sandbag lunges sit in HYROX

Sandbag lunges are station 7 of eight: 100 m with the bag on your shoulders. They test late-race leg endurance and audit your strength reserves more brutally than any other station. By now you have pushed and pulled the sleds and run seven kilometers; the lunges ask the same legs for a hundred more loaded steps.

The station has its own section in the stations guide, and every station is covered in race order in our guide to the eight HYROX stations. The carry before it is covered in our HYROX farmers carry technique guide.

Bag position

Put the bag high across the shoulders behind the neck, hands holding it in place, chest up and eyes forward. A bag that sits low pulls the chest down, and a dropping chest makes each step heavier and the bag more likely to slide. Set it once at the start so you never have to set it again.

1. Lift the bag to the shoulders and settle it behind the neck.
2. Hands on the bag to keep it from shifting.
3. Chest up, eyes forward, trunk braced.
4. First step long and controlled to set the rhythm.

Knee to floor

Take a long step, touch the back knee to the floor every rep, and drive straight up through the front heel into the next step without pausing at the top. The knee touch is not optional: it is what the judge is watching for. A long step makes it easier to reach the floor without folding forward, which keeps the bag where it should be.

Driving through the front heel keeps the work in the legs and hips. Pushing off the toes shortens the step and tips the body forward, and over a hundred meters that small change becomes a lot of extra effort.

Keep the trunk upright through the whole rep. If the chest drops as the knee goes down, the bag rolls forward onto the neck and you end up holding it in place with the arms instead of carrying it on the shoulders. An upright trunk is what lets the legs do all the work.

Cadence

Find a cadence in the first ten meters and hold it; the rhythm is what gets you to a hundred. A steady, repeatable step at a pace you can keep is far cheaper than bursts of fast lunges with stops in between. If you start to slow, keep moving at a slower rhythm rather than stopping: restarting a loaded lunge from a standstill costs more than continuing.

Count in small groups if it helps, for example a set number of steps per side before you check your position. The point is to keep the brain busy with the rhythm rather than with how far is left.

No-reps and stalls

Shallow reps get no-repped by the judges, and stalls happen when the bag slips and has to be re-set. A knee that touches every time at a steady pace beats a fast start that turns into standing still at 60 m with the bag sliding off. Both leaks have the same root: a pace too fast for the legs you have left at this point in the race.

The fix is in training. Our guide to strength exercises for HYROX covers the walking lunges and squats that build the reserve this station draws on.

It also helps to remember what comes next. The wall balls follow the lunges, on the same tired legs, so a controlled lunge that leaves something in the tank is worth more than a fast one that empties it. The finisher has its own guide: our guide to breaking up HYROX wall balls.

Sandbag weight by division

Women Pro uses the Men Open bag. Pro athletes ramp from their Open bag through a midpoint to race weight in Base. Full loads for every station are in our HYROX sandbag lunge weight guide.

Substitutes

The front-rack walking lunge with dumbbells is the engine's closest substitute, followed by a wall-ball-hugged lunge. The ranking is the engine's own:

Our guide to HYROX training without a sandbag covers the same swaps with the kit each one needs.

How the app trains it

Half-distance lunge pieces in normal circuit rounds and a final round that grows to the full 100 m by Peak. The lunge is also a benchmark piece, timed with full rest, so the plan sees whether it is your limiting station. Threshold builds one adaptive plan from your race date, division, goal time, lifts and kit; the weekly structure is in our free HYROX training plan, week by week.

Practice the lunges in training on tired legs, the way they arrive in the race. A rhythm you have rehearsed is far easier to hold when the station starts to bite.
