Best Sandbags for Hyrox Lunge Training

The sandbag at Hyrox station 7 is not the cylindrical sandbag you’ve been training with. It’s specifically shaped, weighted, and balanced - and most home-gym sandbags don’t replicate it well. Train with the wrong bag and station 7 will surprise you on race day. Get this gear choice right and 100m of lunges turns from a soul-crusher into a manageable rep block.

The Hyrox-spec sandbag - what’s actually different

Race-day Hyrox sandbags are:

Long and rectangular (roughly 32” long, 9” wide), not cylindrical
Weighted dynamically - sand shifts within the bag during lunges, demanding constant micro-stabilization
Equipped with handles at the ends and middle (for the squat-clean-to-shoulder transition)
20kg for Open Men, 10kg for Open Women (Pro division: 30kg / 20kg)

If you’ve been training with a cylindrical 20kg dumbbell, a kettlebell on the shoulder, or a tactical “duffel” sandbag - none of those replicate the on-shoulder feel of the Hyrox-spec bag.

TL;DR - top pick

For most Hyrox athletes: the Rep Fitness Sandbag ($90-110 with filler kit). Closest shape match to race-day at non-premium price. Durable across a 16-week training cycle. The smart default.

If budget is no object and you want military-grade durability: GoRuck Sandbag ($165-200). Last forever. Used by special-forces athletes for a reason.

How I tested

Five sandbags, six weeks each, evaluated on:

Shape match - does it sit on the shoulder like the Hyrox bag?
Sand stability - does the inner-fill bag rupture or shift wrong?
Handle durability - handles tear first; how long do they last?
Weight accuracy - does 20kg actually weigh 20kg after 100 lunges?
Repairability - can you fix it when it tears?
Value per pound of usable training

The picks

1. Rep Fitness Sandbag - best overall

Filler weight is sold separately or via Rep’s “filler kit” - pea gravel + sand mix is what most athletes use (more stable than pure sand). Around $90-110 fully kitted.

2. GoRuck Sandbag - best premium / lifetime

Trade-off is price. $165-200 depending on size (40lb, 60lb, 80lb options). For 100m of lunges, you don’t need military durability - but if you’ll also be rucking, doing odd-object work, or training more than just Hyrox, the GoRuck is a one-bag-rules-them-all purchase.

3. Onnit Sandbag (alternative)

Best for: athletes wanting a brand-name sandbag at moderate price.

The Onnit Sandbag is the brand-recognition pick - Onnit is known for Joe Rogan-adjacent fitness gear. Construction is solid; shape is rectangular. Price ~$100-130.

Functional difference vs the Rep is minimal. Pick on aesthetic preference or which one you can find faster on Amazon.

Pros: good shape match, brand recognition, durable Cons: slightly higher than Rep for similar quality Verdict: fine alternative if Rep is out of stock.

4. Yes4All Sandbag - budget pick

The Yes4All sandbag is the budget tier at ~$40-50. The shape is approximately rectangular (closer than a cylindrical sandbag, less perfect than the Rep/GoRuck), and the outer shell is thinner Cordura.

Will it survive 16 weeks of Hyrox training? Probably, with care. But budget for a Rep or Onnit before your second cycle.

5. DIY: Heavy-duty duffel + builder’s sand

Best for: ultra-budget; experimentalists.

You can build a Hyrox-adjacent sandbag for $25 with a heavy-duty duffel and builder’s sand bagged in zip-lock pouches. It’s not pretty, but it works for the first 4-week aerobic-base block while you decide if you’re committed to Hyrox training.

Honest take: by month 2, you’ll want a real sandbag. The DIY route saves $80 but the inner sand-filled-bags-in-duffel approach has poor weight stability. Use as a 4-week stopgap, not a long-term tool.

Pros: $25, immediate Cons: crude, won’t survive heavy use Verdict: stopgap only; budget for a Rep by week 5.

What weight to buy

Hyrox category	Race-day weight	Training start weight	Training peak weight
Open Men	20kg / 44lb	12kg / 26lb	22kg / 48lb
Open Women	10kg / 22lb	6kg / 13lb	12kg / 26lb
Pro Men	30kg / 66lb	15kg / 33lb	32kg / 70lb
Pro Women	20kg / 44lb	12kg / 26lb	22kg / 48lb

Why train slightly heavier than race weight at peak? Builds margin. Race day always feels heavier than the gym. Training to 110% race weight in weeks 11-12 means race day feels like a relief, not a fight.

How to use a sandbag for Hyrox training

Weeks 1-4: form + light volume

3 sets × 25m lunges (race standard 25m × 4 = 100m total)
Light weight (Open Men: 12kg)
Focus: don’t drop, don’t rest mid-25m, controlled cadence

Weeks 5-8: volume blocks

2 sets × 50m lunges
Race weight (Open Men: 20kg)
Focus: pacing, not racing - find sustainable cadence

Weeks 9-12: race-pace + overload

Full 100m unbroken at race weight (one set per session)
One session per week at 110% race weight (Open Men: 22kg)
Focus: accept the discomfort; build mental tolerance

Weeks 13-16: taper

Drop volume to 50% by week 14
Maintain race weight, not heavier
Skip lunge work entirely week 15 and 16 (race week)

Common mistakes

Training only at race weight. Some athletes pick up the bag once a week at 20kg and call it good. Need volume blocks at lighter weight to build durability.
Lunging on hard floor. Use a rubber mat or carpet. Dropping a 20kg bag on hardwood breaks both bag and floor.
Resting mid-50m in training. Trains the wrong skill. Practice unbroken sets even if cadence slows.
Buying too small a bag. A 25lb bag won’t fill the volume need at peak. Get one that goes to at least 50lb capacity.
Skipping the Hyrox-shape match. A cylindrical bag does NOT replicate the lunge-station feel. Don’t train cylindrical.

Storage tips

A loaded sandbag is awkward and dirty (sand leaks). Solutions:

Hang from a hook on the wall (pegboard mount or simple wall hook)
Store in a plastic tote to contain sand leakage
Empty the inner fill bag if storing > 3 months unused (sand absorbs moisture and gets heavy)

Train smarter - log every session

The sandbag is one tool. Whether you’re using it correctly is data. The Hyrox Training Logbook includes a station PR page specifically for sandbag lunges - log each session’s distance, weight, breaks, and felt effort. Find your trajectory; don’t guess.

Best sandbag for Hyrox: FAQ

What sandbag does Hyrox use? Race-day Hyrox uses a long, rectangular shaped sandbag (roughly 32 inches long) with end and middle handles - not a cylindrical bag. It is 20kg for Open Men and 10kg for Open Women, with the Pro division at 30kg and 20kg.

What weight sandbag should I train with for Hyrox? Match your race weight for the main work (20kg Open Men, 10kg Open Women), but build up to it: start lighter for form and volume in early weeks, then overload to about 110% of race weight in your peak weeks so race day feels manageable.

Can I use a normal sandbag for Hyrox training? You can, but a cylindrical or duffel-style bag does not replicate the on-shoulder feel of the Hyrox-spec bag. A long rectangular bag with handles (Rep Fitness, GoRuck, Onnit) trains the actual lunge-station movement far better.

What is the best budget Hyrox sandbag? The Yes4All sandbag at around $40-50 is the cheapest real option and gets you training the movement, though it wears faster than the Rep or GoRuck. The best overall value is the Rep Fitness sandbag at roughly $90-110 filled.

How heavy is the Hyrox sandbag in lb? The Open Men sandbag is 20kg (about 44lb) and Open Women is 10kg (about 22lb). Pro Men is 30kg (about 66lb) and Pro Women is 20kg (about 44lb).
