The HYROX sled push is 50 metres of 150kg (men's open) or 102kg (women's open). Your gym's heaviest sled is 75kg. The race is 8 weeks away. What do you do?
Most athletes do one of two things, both wrong. They either push the 75kg sled for twice as long thinking time-under-tension will substitute for load, or they panic and start travelling to other gyms to find a heavier sled. Both waste training time. There's a third way, three methods that combine to bridge the gap without ever putting 150kg of plates on the gym floor.
Why "just push longer" fails
Sled push at race weight is a strength-endurance task. The first 20 metres is a near-maximal isometric effort to overcome static friction and inertia. The remaining 30 metres is heavy effort against accumulating fatigue in the quads, glutes, and posterior chain.
Pushing a 75kg sled for 100 metres isn't the same workout. The motor recruitment is different. The forces through the hip and knee are different. The mental experience of breaking free of static load is missing. You're training a slightly different exercise that happens to look similar.
Method 1: Combined load, vest + sled
The simplest fix. Add a weighted vest to your bodyweight while pushing the gym sled. A 15kg vest on top of a 75kg sled gives you effective resistance of approximately 90kg through the legs, and importantly, the additional load goes through the posterior chain in the same vector as a race-weight push.
This works because sled push resistance comes from two sources: the sled itself and the lateral force you apply against your own bodyweight to drive forward. Adding to your bodyweight scales the second source linearly.
Method 2: Resistance overload, partner-pull
If you have a training partner, or even a willing gym buddy, a backwards-pulled towel or resistance band creates the static-friction sensation of a heavy sled without needing actual weight. The partner holds the towel and resists with their own bodyweight as you push the sled.
This is particularly useful for the first 5–10 metres of each set, where race-weight pushes are hardest. You can't sustain partner resistance for a full 50 metres, but you can sustain it for the 10 metres where it matters most.
Setup
Loop a heavy resistance band or towel around the back of the sled. Partner stands behind, gripping the band, leaning back to apply opposing force. Push begins, partner resists for the first 10 metres, then releases. Continue the remaining 40 metres against just the sled.
Method 3: Time under tension, paused sled
The third method trains the static-overcoming portion specifically. Push the sled 5 metres, stop, hold for 5 seconds, push another 5 metres, hold, repeat for the full 50 metres. The pauses force you to re-overcome static friction repeatedly, which mimics the first-metre demand of race weight without needing the heavy load.
This method is the most metabolically demanding of the three. Your heart rate will spike higher than a standard race-weight push because of the repeated isometric holds. Use it sparingly, once per week maximum, and never within 48 hours of a race or test.
Programming the bridge
The methods rotate across an 8-week build. Don't use all three in the same week, that's overload territory and you'll burn out. One sled-specific session per week, alternating methods:
| Week | Sled session | Volume |
|---|---|---|
| 1–2 | Method 1 (combined load) | 2 × 50m at 75kg + 10kg vest |
| 3 | Method 2 (partner pull) | 3 × 50m, partner resistance first 10m |
| 4 | Method 1 (combined load) | 3 × 50m at 75kg + 20kg vest |
| 5 | Method 3 (paused sled) | 2 × 50m, 5m/5s rhythm |
| 6 | Method 1 (combined load) | 2 × 50m at 75kg + 25kg vest |
| 7 | Method 2 (partner pull) | 2 × 50m + 1 × 100m flush |
| 8 (taper) | If possible: 1 × 50m at race weight elsewhere | Otherwise: light Method 1 |
The race-weight exposure
If at all possible, get yourself in front of a real race-weight sled at least once in weeks 7–8. A single 50-metre push at full race weight tells you what to expect on race day in a way no bridging method can replicate.
The good news: if you've done the bridging work, that single exposure should feel manageable. The bridge isn't about avoiding the race weight, it's about making sure you're prepared for it when you finally meet it.
Equipment limits don't cap your training. Combined load (sled + vest), resistance overload (partner pull), and time-under-tension (paused sled) bridge the gap. Rotate methods weekly. Get one race-weight exposure in the final 2 weeks if you can.
