Sandbag lunges arrive at station seven with your quads already spent by the sled push, the burpees and six kilometres of running. The weight is modest by design. What makes it hard is 100m of single-leg work at the worst possible moment.
That means the training is exposure, not load. There is no technical trick that substitutes for having done the distance when tired.
Why trust this
Loads and the movement standard are read from the official 26/27 singles rulebook. Two rules worth training to: the bag must remain fully supported by you at all times (resting it on the ground, barricades or your feet is 15 seconds each time), and you do not have to lunge around the turning points.
Loads are 10kg Women's Open, 20kg Men's Open and Women's Pro, 30kg Men's Pro.
1. Tolerance building
Early-block work. The tissue has to get used to this.
- Work: 5 rounds of: 20m walking lunges at race weight, then 200m easy jog.
- Focus: a step length you can genuinely stand up out of, and the bag set high across the shoulders.
- Expect: significant soreness for the first two weeks. That is normal and it settles.
2. Full station repeats
- Work: 3 x 100m at race weight, 2 minutes rest.
- Record: the time for each rep.
- What it tells you: a large drop-off from rep one to rep three means endurance; consistently slow means you need more of session 1 before anything else.
3. Unbroken distance
Building the confidence that you can simply keep going.
- Work: 1 x 150m at race weight, unbroken if possible, standing rests only.
- Rule: if you need to rest, stand still holding the bag. Do not put it down, because on race day that is a penalty and you should never rehearse a movement that costs 15 seconds.
4. Single-leg strength
Off-station work, on a non-lunge day.
- Work: 4 x 8 rear-foot elevated split squats each leg, 3 x 10 step-ups at knee height, 3 x 12 walking lunges unloaded.
- Why: the eccentric control that stops you collapsing into each rep at metre 80.
5. The back half
The one that rehearses the actual race.
- Work: 1km run, then 100m lunges at race weight, then 1km run, then 100 wall balls.
- Frequency: once every two or three weeks. It takes real recovery.
- What it teaches: what the lunges feel like in their actual position, and how much they cost the station that follows.
How to know it is working
| Test | Do it | Progress looks like | |---|---|---| | 100m at race weight, fresh | Monthly | Faster, fewer standing rests | | 3 x 100m (session 2) | Monthly | Smaller drop-off across the three | | Back half (session 5) | Every 3 weeks | Lunge time closer to your fresh time |
The drop-off across session 2 is the most useful signal. If rep three is more than a quarter slower than rep one, you need more tolerance work before anything else.
What tends to fail first
Quads, then the ability to stand up out of the bottom, then the bag position. In that order, and usually somewhere between 60m and 80m.
The bag creeping forward is the tell that your trunk has gone, not your legs. Re-set it standing still rather than fighting it through the next ten reps, because a bag that has slipped pulls you into flexion and makes every subsequent rep harder.
If you are stopping before 60m, the problem is exposure and session 1 is where you should be living.
Putting it into a week
| Day | Session | |---|---| | Mon | Single-leg strength (4) | | Tue | Threshold run | | Wed | Rest or easy | | Thu | Tolerance (1) early block, full station (2) mid, back half (5) late | | Fri | Strength | | Sat | Long easy run | | Sun | Rest |
Honest limitations
Do not train heavier than race weight. The bag is not the challenge and adding load to a movement you will perform over 100m raises injury risk for a quality the station does not test.
Sandbag shape and filling vary between venues, and a bag that has settled unevenly genuinely is harder to carry. You cannot prepare for that specifically.
If you have a knee or lower back history, loaded walking lunges at volume deserve a professional conversation before you build a block around them.
And the honest framing: this is a consequence station. If your lunges collapse, look at how you paced the sled push.

Frequently asked
How do you train for HYROX sandbag lunges?
Distance at race weight, repeatedly, on tired legs. The load is modest by design; 100m of single-leg work at station seven is what makes it hard, so add metres rather than kilos.
Should you train sandbag lunges heavier than race weight?
Generally no. The bag is 10kg, 20kg or 30kg depending on division, which is not heavy in isolation. Training heavier builds a quality the station does not test and increases injury risk on a movement you will do 100m of.
Why do my legs fail on the sandbag lunges?
Usually because of the sled push at station two and 6km of running, not because of the lunges. It is a consequence station: if it feels impossible, the pacing error happened earlier.
