Hyrox Plan: Gym Only (No Sled/SkiErg)

What "Gym-Only" Actually Means for HYROX^®

A standard HYROX^® race requires a SkiErg, a sled, a sandbag, a rowing machine, and a set of wall balls. Most commercial gyms have none of those — or at best one or two. For athletes without access to a specialized functional fitness facility, this creates a real problem: how do you prepare for eight specific stations when you can only replicate two or three of them?

The short answer is that you train the underlying physical qualities rather than the exact movements. Every HYROX^® station is a proxy for something broader — posterior chain endurance, pulling power under fatigue, grip capacity, hip extensor strength, aerobic recovery between efforts. Those qualities can be built in any well-equipped gym. The substitutes are not perfect replications, but they are effective preparation tools.

Data from ROXBASE's 700,000+ athlete profiles consistently shows that an athlete's finishing time is more tightly correlated with their aerobic base and general posterior chain capacity than with their station-specific skill on any single movement.^[1] That is good news for gym-only trainers: the physiological foundation transfers, even if the exact motor pattern does not.

This guide covers the full substitution framework, a weekly training template built entirely around standard gym equipment, and how to structure the program across a 12-week build.

The Eight Stations and Their Gym Substitutes

Each official HYROX^® station has at least one effective gym alternative. None are identical to the race movement — the goal is to train the same muscle groups, energy systems, and postural demands, not to replicate the exact implement.

SkiErg (1,000m per station) The SkiErg loads the lats, shoulders, and core through a double-arm pull-down pattern while demanding significant aerobic output. In a standard gym, kneeling double-arm cable pull-downs on a rope or bar attachment replicate the pulling mechanics well. Set the stack to a moderate load and perform 3–4 sets of 40–60 reps at a controlled tempo — the goal is cardiovascular output plus lat endurance, not maximal strength. A rope attachment most closely mimics the SkiErg grip and shoulder position.^[2]

Sled Push (approximately 25m per lap, 8 laps) The Sled Push is a low-back-friendly quad and glute drive at moderate load — the defining station for many athletes. If your gym has a prowler or pushing sled, use it. If not, a loaded barbell plate push on a smooth rubberized floor is a viable substitute: stack 25–45kg plates on a single plate base and push with straight arms. Alternatively, heavy Bulgarian split squats and loaded step-ups develop the same quad-dominant drive pattern and are a legitimate secondary option when floor pushing is not available.

Sled Pull (approximately 25m per lap, 8 laps) The Sled Pull is a horizontal pulling movement — you face the sled and drag it toward you using a rope. The seated cable row with a rope attachment is the closest gym substitute: high reps, moderate load, sustained tension. Set the pulley to low, attach a rope, sit on the floor facing the stack, and pull in sets of 20–30 reps with minimal rest. Straight-arm cable pull-downs performed in a staggered stance also build the lat and upper back endurance the pull demands.

Burpee Broad Jumps (80 reps per station) This station has the most direct gym equivalent: box jump burpees or tuck jump burpees. The broad jump component requires some open floor space, but the explosive hip extension and aerobic demand are well replicated by either variation. Perform the burpee, land in a partial squat, then either jump onto a low box (40–50cm) and step down, or tuck jump in place. The box version reduces joint impact for higher-volume training.

Rowing (1,000m per station) Most commercial gyms have rowing machines. This is the one station where there is no need for a substitute — the equipment is the same. Rowing at 2:00–2:30 per 500m pace with a consistent stroke rate of 24–26 strokes per minute is appropriate for most intermediate athletes. If your gym has no rower, the ski erg substitution described above applies in reverse — use the rower for SkiErg sets and cable pulls for Sled Pull sets.

Farmers Carry (24kg/hand for women, 32kg/hand for men, 200m per station) Dumbbell carries are a direct substitute and arguably superior for building unilateral stability. Load two dumbbells at or above race weight, pick them up, and walk. If your gym has limited floor space, set a 20–25m turnaround point and mark your laps. Trap bar carries at race-equivalent load also work well. The key is training at race weight or above — many athletes under-load their carry practice and are surprised by the grip and trap fatigue on race day.^[3]

Sandbag Lunges (10kg/20kg, 100m per station) Barbell reverse lunges or dumbbell walking lunges are the primary substitutes. The sandbag adds a rotational challenge because the weight is unstable, so increase the training load slightly to compensate — if your race category calls for 20kg, train lunges at 25–30kg loaded. Bulgarian split squats and goblet squats also develop the hip flexor, quad, and glute endurance the station demands, and should be included as supplementary movements.

Wall Balls (4kg/6kg, 75–100 reps per station) Dumbbell thrusters are the closest available substitute in a standard gym. Hold two dumbbells at shoulder height, squat to parallel, and drive up through the hips while pressing overhead. The loading pattern and breathing demands are highly similar to wall balls. Use 8–12kg total load (4–6kg per dumbbell) for women, 12–16kg total for men. Medicine ball squat-to-press on a cable machine is a secondary option if dumbbells are not available.

The Aerobic Foundation: Cardio Without a SkiErg

Every HYROX^® athlete needs a strong aerobic base. The eight 1km run legs between stations take up more total time in the race than all eight stations combined for most competitors. A gym-only training block must address this.

Standard gym cardio options in descending order of relevance for HYROX^®:

1. Rowing machine — builds the same posterior chain endurance as the race station and develops aerobic capacity with minimal joint impact. The closest overall substitute for the SkiErg in terms of muscle involvement.
2. Treadmill running — most directly replicates the run legs. Zone 2 treadmill running (conversational pace, approximately 60–70% maximum heart rate) builds the aerobic base that keeps your 1km splits consistent late in the race.
3. Stationary bike — lower specificity than rowing or running but excellent for Zone 2 volume without joint stress. Use for recovery days or when managing impact load.
4. Stairmaster or step mill — develops the hip extension and leg endurance relevant to the station work, with moderate aerobic demand.

The target is 3–4 cardio sessions per week, with the majority at low intensity — what exercise physiologists call Zone 2 — and one higher-intensity session per week to develop lactate threshold.^[4] Most gym-only athletes default to moderate effort on machines because there is no external pace to anchor them. Use heart rate as your guide: Zone 2 should feel genuinely conversational.

See the HYROX^® Training Zones guide for how to calculate your zones and structure intensity distribution across the week.

12-Week Gym-Only Training Template

The template below is structured for an intermediate athlete — someone with 6–12 months of consistent training, capable of completing the race but targeting a specific time improvement. Beginners should reduce volume by 20–30% in weeks 1–4 and increase gradually.

The program divides into three phases: base building, race-specific development, and peaking.

Phase 1 — Base Building (Weeks 1–4)

Focus: aerobic volume, movement quality, posterior chain capacity.

Day	Session	Key Movements
Monday	Strength — Lower Body	Romanian deadlift 4x8, goblet squat 3x12, reverse lunge 3x10/side, leg press 3x15
Tuesday	Cardio — Zone 2	45–60 min rowing or treadmill at 60–70% HRmax
Wednesday	Station Circuits	Cable pull-downs 4x40 reps, dumbbell thrusters 4x15, dumbbell farmers carry 3x50m
Thursday	Cardio — Tempo	20–25 min treadmill at race pace effort (75–80% HRmax) + 10 min cool-down
Friday	Strength — Upper + Core	Seated cable rows 4x15, pull-ups or lat pull-down 3x10, pallof press 3x12/side, plank variations
Saturday	Long Cardio	60–75 min rowing or treadmill, Zone 2 throughout
Sunday	Rest	Full rest or 20 min light walking

Phase 2 — Race-Specific Development (Weeks 5–9)

Focus: station simulation circuits, intensity increase, aerobic-to-strength transition training.

Day	Session	Key Movements
Monday	Strength — Heavy Lower	Trap bar deadlift 4x5, Bulgarian split squat 3x8/side, walking lunges 3x20 steps
Tuesday	Station Circuit A	3 rounds: cable pull-downs x40, seated cable row x30, dumbbell farmers carry 50m — 90 sec rest between rounds
Wednesday	Cardio — Zone 2	50–60 min rowing or treadmill, conversational pace
Thursday	Station Circuit B	3 rounds: box jump burpees x15, dumbbell thrusters x20, dumbbell reverse lunges x20/side — 2 min rest between rounds
Friday	Combined Session	10 min treadmill at race pace → 3x20 cable pull-downs → 10 min treadmill → 3x20 dumbbell thrusters → cool-down
Saturday	Long Cardio	70–80 min rowing or treadmill, Zone 2
Sunday	Rest	Full rest

Phase 3 — Peaking (Weeks 10–12)

Focus: volume reduction, sharpening, race simulation, recovery.

Day	Session	Key Movements
Monday	Strength — Maintenance	Romanian deadlift 3x6, reverse lunge 3x8/side, cable rows 3x12 — loads unchanged, volume down 25%
Tuesday	Race Simulation	Half-distance station circuit: all 8 substitutes in sequence at race weight, half the reps, 60m carries
Wednesday	Easy Cardio	30 min rowing or treadmill, Zone 1 only
Thursday	Sharpener	3x5 min treadmill at race pace with 3 min easy between — stay fresh, do not push to max
Friday	Rest	Full rest
Saturday	Light Movement	20–30 min easy bike or walk, mobility work
Sunday	Rest	Pre-race rest

Loading the Stations: Weight and Reps to Train With

One of the most common gym-only training mistakes is training at loads and volumes that bear no resemblance to race demands. The race has fixed weights and fixed distances — your training should regularly incorporate race-specific loading.

Race weights and gym training targets:

Station	Race Spec (Open Women / Open Men)	Gym Substitute	Training Load
SkiErg	1,000m	Cable pull-downs (rope)	3–4 sets of 40–60 reps, 90 sec rest
Sled Push	+102kg / +152kg	Plate push or prowler	4–6 laps of 20–25m, heavy load
Sled Pull	+78kg / +103kg	Seated cable row (rope)	4 sets of 20–30 reps, moderate load
Burpee Broad Jumps	80 reps	Tuck jump burpees / box jump burpees	4x20 reps, building to 4x20
Rowing	1,000m	Rowing machine	4x250m with 60 sec rest
Farmers Carry	2x24kg / 2x32kg	Dumbbells at race weight	4x50m, no rest until full set done
Sandbag Lunges	10kg / 20kg	Barbell or dumbbell lunges	4x20 reps at race weight +20%
Wall Balls	4kg / 6kg, 75–100 reps	Dumbbell thrusters	4x20–25 reps at 8–12kg total

Train at race weight on carries and lunges from week 5 onward. Training below race weight for these stations builds aerobic capacity but not the grip and postural endurance that becomes critical in the final two stations of the race.^[5]

Managing the Run Component Without Outdoor Access

HYROX^® athletes who rely on treadmill running face a real limitation: treadmill running is slightly easier than road running at the same pace due to the moving belt reducing the work of propulsion. To compensate, set the treadmill incline to 1–2% throughout all runs. This increases caloric demand and more accurately replicates the energy cost of running on flat ground.

For race-pace work, use the treadmill confidently — the movement pattern is close enough to road running for pace-specific training. For long Zone 2 runs above 60 minutes, the rowing machine is a valid substitute when treadmill access is limited or when your joints need lower-impact volume.

One practical strategy for athletes with limited cardio equipment access: alternate weekly between rowing-dominant and treadmill-dominant aerobic sessions. This builds aerobic capacity across two modalities while also developing the rowing machine fitness that transfers directly to the Rowing station on race day.

The HYROX^® HIIT training guide covers how to structure high-intensity intervals for athletes who want to add race-pace efforts to their gym-based aerobic work.

What You Are Still Missing — and How to Compensate

Honest gym-only training requires acknowledging what is genuinely difficult to replicate. Two stations present real challenges:

SkiErg: The SkiErg recruits the lats, triceps, and core in a specific overhead-to-hip pull-down pattern that cable machines approximate but do not perfectly match. The standing body position and ballistic hip hinge component of the SkiErg stroke are distinct. Compensate by adding banded or cable pull-throughs and single-arm lat pull-downs to develop the lat-to-hip connection. If you can access even occasional SkiErg sessions at a specialty gym or box in the final 6 weeks, prioritize two or three sessions to familiarize yourself with the movement.^[6]

Sled Push / Pull: The horizontal force production in Sled Push — the angled body position, the hip drive against resistance — is partially trained by plate pushes and lunges, but the specific pattern of pushing against an external load while moving is hard to replicate at race intensity. Heavy step-ups, prowler alternatives, and loaded incline treadmill walking all develop relevant capacity, but if a prowler push option exists in your gym (some commercial gyms have them on astroturf areas), this should be your highest-priority station substitute.

Neither of these gaps means gym-only preparation is inadequate. Athletes who train intelligently without specialist equipment regularly compete well. The gap narrows further once you apply the loading and volume targets above — consistent exposure to the substitute movements over 12 weeks produces substantial adaptation.

For more on how to build race-ready fitness without specialist equipment, see the HYROX^® Home Training guide, which covers alternatives for athletes with even more limited access than a standard gym.

Frequently Asked Questions

Can I get competitive HYROX^® results training only in a standard gym? Yes, with realistic expectations. For first-time competitors, gym-only preparation is entirely sufficient to finish comfortably and build the physical base for future improvement. For athletes chasing sub-60-minute times, targeted exposure to the actual implements — particularly the SkiErg and sled — in the final 8 weeks makes a measurable difference. A hybrid approach (gym-based training with monthly sessions at a functional fitness facility) is the most practical middle ground for most athletes.

What is the biggest physical gap between gym-only training and race-day demands? Grip endurance under accumulated fatigue is the most common surprise. By stations 6 and 7 (Farmers Carry and Sandbag Lunges), grip fatigue from earlier stations has already set in. Gym-only athletes who do not train grip-intensive movements at race weight — especially farmers carries at full load — consistently report that the carry station feels harder than expected despite aerobic fitness being adequate. Train your carries heavy and at race weight from week 5 onward.

How should I use the rowing machine for HYROX^® preparation? Two ways: as an aerobic base builder, and as a direct race station substitute. For base building, 45–60 minutes at Zone 2 intensity (keep stroke rate at 20–22 and focus on long, controlled pulls) is highly effective. For race-specific training, 4x250m intervals with 60–90 seconds rest at 2:00 per 500m target pace builds the lactate tolerance and rowing-specific endurance you will need. Do not exclusively train long steady-state rows — the race station is a sustained push effort, not a prolonged aerobic event.

Do I need to run outside at all, or can I replace all running with treadmill work? Treadmill running at 1–2% incline adequately replicates road running for the purposes of HYROX^® preparation. The physiological adaptations — aerobic capacity, running economy, lactate threshold — develop comparably across both surfaces. The one limitation is that treadmill running does not develop the slight lateral stability demands of outdoor surfaces, but this is unlikely to affect race performance at the amateur level. If outdoor running is accessible and enjoyable, use it — but it is not a requirement.

How soon before race day should I try to access the actual HYROX^® stations? Ideally, schedule at least two to three exposure sessions on actual HYROX^® equipment — SkiErg, sled, sandbag — in the final 6–8 weeks before the race. The goal is not to rebuild your fitness; your fitness is already built. The goal is to familiarize your nervous system with the specific movement patterns and calibrate your effort at race weight. One session per station is enough to avoid being surprised on race day. Many athletes access these through open gym days at CrossFit or functional fitness facilities, or by entering a warm-up event in their region.
