Cardio + HYROX Substitution Calculator
Swap one cardio modality for another at equal effort — running, rowing, cycling, SkiErg — and get HYROX station substitutions built around the equipment you have.
How cardio substitution works
Every modality has an approximate energy cost (its MET value) at a given intensity. To swap one for another at equal effort, the calculator scales time by the ratio of those costs — so a session on a lower-cost machine takes a little longer to match the same work.
Why equal effort isn't the same as identical training
Matching energy cost is a good starting point, but rowing, running and cycling load your body differently — impact, muscle emphasis and skill all vary. Use the equivalent as a guide, then let heart rate and perceived effort fine-tune the session.
Running vs rowing vs cycling vs SkiErg
Running is highest-impact and most cardiovascularly demanding minute for minute; rowing and SkiErg add strong upper-back and trunk work; cycling is lowest-impact and easiest to sustain. Swapping between them is how you keep training when a machine, an injury or the weather gets in the way.
How to train for HYROX without a sled
No sled is the most common home-gym gap. Heavy incline treadmill walks, hill repeats, heavy step-ups, wall drives and loaded marches all train the same low, grinding leg drive the sled push demands — pick the one your setup allows and load it heavy.
How to replace the SkiErg in HYROX training
The SkiErg trains a hard, rhythmic straight-arm pull. A rower, a BikeErg, straight-arm cable pulldown intervals or banded high pulls all hit that upper-back and trunk pulling stimulus when you don't have one.
How to replace rowing in HYROX
Rowing is a leg-drive-led full-body pull. Substitute a SkiErg, a bike, or run intervals matched to the same duration and effort — the goal is the aerobic cost, not copying the stroke exactly.
HYROX substitutions for home and commercial gyms
Pick the station, tell the calculator what you own, and it returns the best substitution you can actually do, with alternatives, target stimulus and suggested volume. It works from a fully-kitted box down to bodyweight-only at home.
Match the stimulus, not just the movement
A good substitute reproduces what the station trains — grip endurance, horizontal pushing, aerobic pulling — rather than mimicking how it looks. That's why heavy step-ups can stand in for a sled and dumbbell thrusters for wall balls: same demand, different tool.
Frequently asked questions
- Can I really replace running with rowing?
- Yes — at equal effort you can swap them, though rowing adds upper-body work and less impact. The calculator gives an equivalent duration; let heart rate confirm you're matching the effort.
- How do I train for HYROX without a sled or SkiErg?
- Switch to the HYROX mode, deselect the equipment you don't have, and the tool returns substitutions that train the same stimulus — heavy incline walks for the sled, a rower or cable pulls for the SkiErg.
- Are these substitutions official HYROX equivalents?
- No. They're training approximations to help you keep the right stimulus when you lack equipment — not official race-equivalent standards.
- Which intensity should I choose?
- Match it to the session's purpose: easy for aerobic base, moderate for tempo, hard or race for threshold and race-pace work. Intensity changes the equivalent time.
