Grip strength training for Hyrox: why your forearms fail first
The farmers carry sits at station 7. By the time you get there you've done the SkiErg, sled push, sled pull and row, and every one of them has been quietly draining your grip before you've even picked up a kettlebell.
Then, with your heart rate high, less blood reaching your forearms and sweaty hands on the handles, you're asked to carry near-maximal weight for 200m. A lot of races unravel here, and it's usually grip that goes first, well before the legs.
Why grip fails before legs do
Your forearm muscles are small compared with your quads or glutes. Small muscles tire faster under a sustained isometric load, and a farmers carry is exactly that: one long squeeze with no moving rep to rest between. Add the grip fatigue from the sled pull rope and the rowing handle before it, and your forearms are partly spent before the carry even starts.
Under fatigue your instinct is to grip harder and white-knuckle the handles. That speeds up the fade. A firm but relaxed grip, letting the kettlebells hang in a hook position, uses less forearm muscle for the same hold and buys you more time before your hands open.
Training grip strength for Hyrox specifically
General grip work like the odd dead hang helps, but race day asks for something more specific: grip endurance under fatigue. Train max strength and endurance separately.
Max strength (build the ceiling): Heavy farmers carries, 2-3 sets of 20-40m at a weight that's properly hard to hold, once or twice a week. This raises your ceiling, so race weight feels lighter compared with what you can handle.
Grip endurance (build the floor): Lighter carries for longer, 60-90 seconds continuous, done when you're already tired from other work, ideally at the end of a session. This trains the exact skill you need: holding on when your forearms are already cooked.
Fatigue-stacked practice: Every week or two, put sled work straight before a carry, copying the race order. Sled pull into farmers carry. It's the closest you'll get to arriving at station 7 with tired forearms, and it's the session most people skip because it's uncomfortable.
Grip fatigue starts three stations earlier
Grip fatigue shows up earlier than most people track. How the sled pull loads your grip is where it begins, because the rope needs a strong hold at an awkward angle. The rowing handle, pulled at pace for 1000m, adds 4-6 minutes of continuous grip load before you reach the carry. If you only train grip in isolation, you're preparing for a different problem from the one you'll face on race day, where your grip is already heavily fatigued before the station that tests it most.
That's why the fatigue-stacked practice above matters more than max-strength work alone. A strong grip when you're fresh tells you very little about how it'll hold up after three stations have already taken a bite out of it.
The technique fix that costs nothing
Most grip failure in a farmers carry starts as a technique problem. A hook grip, with the thumb wrapped loosely around the handle, cuts forearm activation and extends how long you can hold a given weight. Practise it in training so race day isn't the first time you try it.
Gardening gloves are legal in Hyrox and deal with sweaty handles directly if slipping is your problem more than fatigue. They're cheap and they work, so try them in a training session before you race in them.
A simple two-day grip programme
You don't need a dedicated grip day to fix this. Two short additions to sessions you already do will get you most of the way.
Day 1 (paired with a strength session): 3 sets of heavy farmers carries, 20-40m, resting 90 seconds between sets. Go heavy enough that the last 5m of each carry is properly hard.
Day 2 (paired with a conditioning session, ideally at the end): 2-3 sets of lighter carries for 60-90 seconds continuous, done once you're already tired from the main session. People skip this one because it's unpleasant when tired, and that's exactly why it matters.
Every 1-2 weeks: Put a sled pull directly before a farmers carry, copying the fatigue order of the race. It adds ten minutes to a session you're already doing.
Give it four to six weeks before you judge whether it's working. Grip endurance responds more slowly than most strength qualities, so one good session won't show on the scoreboard. Consistency will.
Recovery matters here too
Grip and forearm recovery gets ignored in most plans built around legs and lungs. If your forearms are always sore, or your carry capacity is dropping week to week, treat it as a sign to recover more.
Collagen supports connective tissue, including the tendons that take the load in a heavy carry. If you've read our piece on collagen for athletes, the logic that applies to knees and shoulders applies to the tendons running through your forearms and wrists as well.
Collagen is bovine sourced, £18.99 for 300g, taken at 10g a day.
Grip is trainable like anything else. Most Hyrox athletes only ever train it as an afterthought tacked onto a deadlift. Give it two proper slots a week and station 7 stops being the place your race falls apart.
