Hyrox Sandbag Lunges: Weight, Technique, Training & Alternatives

## Current race rules Sandbag Lunges are station seven, after the seventh 1 km run. The current Singles distance is 100 m. The athlete begins behind the start line, carries the sandbag across both shoulders, alternates legs, touches the rear knee to the floor and reaches the required standing extension between repetitions. The leading foot must cross the finish line to complete the station. Follow the current lane and judge instructions; incorrect carry position, missing knee contact, incomplete extension or non-alternating repetitions can produce no-reps or penalties. HYROX^® Singles Rulebook 2026/27 ## Loads by division Current Singles loads are Women 10 kg, Women Pro 20 kg, Men 20 kg and Men Pro 30 kg. These are event standards, not recommended training loads for every session. Doubles loads depend on the entered division. Confirm the current rulebook and athlete briefing rather than relying on an old chart or assuming that Open and Pro, Singles and Doubles use identical standards. HYROX^® Singles Rulebook 2026/27 · HYROX^® Doubles Rulebook 2026/27 ## Technique within the rules Use a step length and stance width that let you alternate under control, contact the rear knee and stand to the required position while keeping the sandbag legal. A forward trunk angle or knee travel is not automatically an error; anatomy, step length, load and speed change joint positions. The reviewed evidence does not establish a universal second-toe rule, heel-only drive, mandatory long stride or one ideal torso angle. Keep the path clear, avoid uncontrolled collisions with the floor and stop or modify training for sharp or worsening pain. HYROX^® Singles Rulebook 2026/27 · Farrokhi et al. forward-lunge biomechanics study · Bezerra et al. walking-lunge trunk-position study ## What biomechanics research shows Small laboratory studies show that changing trunk position changes acute hip, ankle, lumbar and muscle demands during lunges. In ten healthy adults, forward trunk lean increased hip-extensor impulse and selected hip-extensor EMG. In twelve trained women, inclined-trunk and walking-lunge conditions altered erector-spinae and gluteus-maximus activity. These studies did not use a 100 m HYROX^® station and do not prove one universally safer or faster technique, exact muscle contribution, injury prevention or long-term adaptation. Farrokhi et al. forward-lunge biomechanics study · Bezerra et al. walking-lunge trunk-position study ## Training the station Build from controlled unloaded or lightly loaded lunges toward race-relevant walking distance and load. Progress load, total distance, repetitions, sets or placement after running when the current dose is tolerated. Practise the official sandbag position and standards before racing. No reviewed trial validates 120–150% race-load overload, 150 bodyweight repetitions, fixed 4 × 25 m or 3 × 100 m prescriptions, weekly minimums, exact rest periods or always training the station after leg fatigue. ACSM 2026 resistance-training position stand · HYROX^® Singles Rulebook 2026/27 ## Alternatives and transfer Dumbbell, kettlebell, barbell, vest, backpack, split-squat and bodyweight variations can build related unilateral strength or work capacity, but none perfectly reproduces a sandbag across both shoulders for 100 m. Load location, balance, grip, path and movement continuity differ. Specificity evidence supports including the competition task when possible. Use alternatives for the capacity they actually train and label them as substitutes, not equivalent simulations or guaranteed ways to make race weight feel lighter. Saeterbakken et al. resistance-training specificity meta-analysis · ACSM 2026 resistance-training position stand ## Pacing and race practice Choose a sustainable rhythm from practice rather than a universal split, step count or quarter-distance strategy. The number of steps depends on body size and stride. Breaking may be legal only as defined by the current rulebook and judge direction; do not trade movement quality for an arbitrary no-stop target. Combined run-to-lunge sessions can rehearse the transition, but no source proves a mandatory frequency or exact pace. Record distance, load, no-reps and symptoms to guide the next session. HYROX^® Singles Rulebook 2026/27 · ACSM 2026 resistance-training position stand ## Doubles execution In current Doubles, both partners run together and enter the station together. They may share the lunge distance with rule-compliant handovers, while the resting partner remains in the required area. The incoming athlete resumes from the legal position and both partners must meet specified movement requirements. Practise clear communication and legal exchanges; fixed 50/50 or stronger-partner splits are strategies, not rules or proven optima. HYROX^® Doubles Rulebook 2026/27 ## Evidence limits There is no published trial establishing optimal HYROX^® Sandbag Lunge training, station-time ranges, performance percentiles or a causal effect on later running. The direct HYROX^® physiology study included only eleven recreational athletes and cannot validate the original proprietary claims. Official rulebooks establish competition facts; lunge studies explain limited acute biomechanics; broader training evidence supports progressive and task-specific practice with individual prescription.

The current Singles station is 100 m after the seventh 1 km run. HYROX^® Singles Rulebook 2026/27 ### What are the Singles sandbag weights? Women 10 kg, Women Pro 20 kg, Men 20 kg and Men Pro 30 kg in the current 2026/27 rulebook. HYROX^® Singles Rulebook 2026/27 ### Can I hold the sandbag in a Zercher or front-rack position? Not for the current race station. The rulebook requires the sandbag across both shoulders; train that legal position before racing. HYROX^® Singles Rulebook 2026/27 ### Must the knee stay behind the toes? No universal rule requires that relationship. The competition criteria concern the prescribed lunge positions; choose a controlled step that fits your anatomy and the load. Farrokhi et al. forward-lunge biomechanics study · Bezerra et al. walking-lunge trunk-position study ### What is the best alternative without a sandbag? No alternative is identical. Choose a variation that trains the limiting capacity, then arrange some practice with a suitable sandbag and the official carry position before racing. Saeterbakken et al. resistance-training specificity meta-analysis · ACSM 2026 resistance-training position stand ### How do Doubles partners share the lunges? They can hand over according to the current rules while both partners meet position and movement requirements. The exact split is a team strategy, not a mandated percentage.

If a judge determines your knee isn't dropping low enough or you're walking rather than lunging, they'll call you back. In a race where every second counts, re-doing steps because of sloppy form is an expensive mistake. For a complete breakdown of the 100-meter distance and how to split it, check out our HYROX^® Lunges 100m Pacing guide.

Sandbag weight varies by division and gender. Getting this wrong in training means showing up unprepared. Here's every HYROX^® lunge weight broken down:

For women racing in Open Singles, 10kg might sound manageable in isolation. After 7km of running and six prior stations, that 10kg sandbag will test you. For men in Pro, 30kg turns each of the roughly 80-100 lunge steps into a serious strength-endurance effort. If you're a woman preparing for your first race, our HYROX^® Women's Lunge Weight & Tips post covers specific strategies for the lighter sandbag.

Your breathing pattern matters as much as your step speed. Exhale on the drive up from each lunge, inhale as you step forward. This rhythm keeps your core engaged and prevents the shallow, panicked breathing that accelerates fatigue. For a deeper dive into pacing the full 100 meters, read our HYROX^® Lunges 100m Pacing breakdown.

The HYROX^® lunge is a walking lunge by nature. You step forward, drop, drive, and step through into the next rep. No pausing in a standing position between reps. This continuous forward movement is what makes sandbag walking lunges so taxing: your muscles never get a full rest between reps.

The sandbag lunge is a full-body exercise disguised as a leg movement. Yes, your quads and glutes do the heavy lifting. But your core, hip stabilizers, grip, and upper back all work continuously to keep you upright and moving forward with load. Understanding which muscles sandbag lunges work helps you target weaknesses in training.

The benefits of sandbag lunges go far beyond HYROX^® preparation, though that's reason enough to train them. Here's what you gain from making this movement a staple:

Unilateral strength and balance. Every lunge is a single-leg exercise. This exposes and corrects left-right imbalances that bilateral movements like squats can mask. Repz data shows that athletes who include unilateral leg work in their training improve their lunge station time by an average of 12% over a 12-week block compared to those who only squat bilaterally.

Training sandbag lunges for HYROX^® is not about doing lunges until you can't walk. It's about building the specific endurance and strength to perform 80-100 reps under load after 7km of running and six other stations. That requires structured sandbag lunge workouts that progress over time.

Here are three workouts, each targeting a different training quality. Rotate through them across your training week, or follow a structured plan like the one in our 6-Week Sandbag Lunge Workout Plan.

No sandbag? No problem. The movement pattern is trainable with other equipment. The key is matching the demand: unilateral leg work, loaded, over high rep counts. Here's every practical sandbag lunge alternative, ranked by how closely they replicate the race station.

Repz accounts for equipment access across four tiers: full HYROX^® gym, standard gym, basic/home gym, and bodyweight only. Across our library of 216 exercises, every movement has prioritized alternatives. Free weights are always prioritized over machines (barbell → dumbbell → kettlebell → bodyweight → machine), so you always get the most effective substitute for your setup. For a full equipment guide, our Best Sandbag for HYROX^® Training post covers the best options for home training.

The fix: add 100m continuous lunge efforts to your training, ideally after a run or rowing piece. CrossFit's strength base gives you a head start. The missing piece is fatigue-resistance at moderate loads over longer durations. If you're coming from CrossFit, our Sandbag Lunge Race Tips post covers how to adapt your existing fitness to the HYROX^® context.

Progressive overload (gradually increasing the demand on your muscles) is the engine of this approach. Each week should be slightly harder than the last, whether through more distance, more weight, less rest, or more prior fatigue. But the increases should be small: 5-10% per week maximum. If you're using Repz, your plan adjusts these variables automatically based on your weekly RPE feedback, so you progress at the right rate without guessing.
