Sprint is the high-intensity class, an hour built around short repeated efforts on the turf and the ergs. You work hard, recover briefly, then go again, using formats like AMRAPs and EMOMs to push your top end without turning the session into one long effort.
An athlete driving a loaded sled hard across the turf. Low body angle, full leg drive, motion blur behind.
Urgency and speed. Centre safe: this crop trims both sides.
The clock or timer screen on the wall with athletes working underneath it, slightly out of focus.
The clock is the character in this class. Make it the subject.
Interval training, in practice: the hour is cut into two or three blocks, each with its own clock and its own job. Working near your limit in repeated doses is what raises the top end, and the rests between efforts are kept deliberately short to hold you close to it. Coached start to finish, scaled to whoever is in the room.
Two formats do most of the work:
Close enough. HIIT means hard efforts with short rests, and that's most of a Sprint session. The difference is what you're doing during the effort: sleds, ergs, carries and barbells rather than star jumps in a studio. Same principle, more useful work.
Engine is one long effort and raises your ceiling. Sprint is short efforts repeated, and teaches you to work close to it, so one does not stand in for the other. Most people here do both in the same week, and the ones who race add Complete.
Want the whole race in one go rather than in pieces? That's Complete, on weekends.
Going out too hard is the most expensive mistake in any race. An EMOM punishes it immediately and cheaply, every minute, until you stop making it.
Long steady work builds the base and hard repeated efforts lift the top end. You need both, and Sprint is where the top end gets trained.
You are never asked to hold an effort for an hour, only for about three minutes at a time, which is what makes a hard intensity trainable.
Blocks are timed, not counted, so nobody waits and nobody gets left behind. First-timer and competitor finish the same session at the same moment, on different numbers.
Rounds, reps, or a time. Written down, and the same session comes round again. You find out whether the work is working.
A HYROX is eight hard efforts with a run in between. Sprint trains that shape at a scale you can repeat twice a week and still recover from.
The blocks change every session. The shape doesn't.
Raise the heart rate, then movement prep for whatever the blocks are about to ask for.
A coach walks the blocks, sets your loads and gives you a target. You start knowing exactly what you're aiming at.
Two or three of them, each with its own clock and its own job. Hard, short, repeated. Rest between blocks, not much within them.
Bring the heart rate down, stretch out, done.
Three blocks. Three minutes rest between them.
Scaling: the loads and the calories come to you. The clock doesn't move. That's the point.
A class runs an hour, with up to 30 on the floor. A coach sets your loads and your targets before the first clock starts, so you spend the session working rather than wondering. Scaled from day one.
Bring trainers, water and a towel. The loads and targets are set for you before the first clock starts, so the intensity is scaled from your first session. Check the live timetable for exact days and times.

Reassurance shot. Show the scaling happening, not the suffering.
As many rounds as possible. You get a list of movements and a block of time, and you repeat the list until the clock stops. Your score is how far you got.
Every minute, on the minute. At the top of each minute you start a set piece of work, and whatever's left of that minute is your rest. Finish faster, rest longer.
Yes, coached. The loads scale to you and the clock stays the same, so you get the same session as everyone else at a weight that fits. If you've never trained like this, start with Engine and add Sprint in week two or three.
Engine is one long effort. Sprint is short efforts repeated. Engine raises your ceiling; Sprint teaches you to work close to it. Most people here do both.
An hour, warm-up to cool-down, with two or three timed blocks in the middle.
Once or twice a week is plenty. It's the hardest thing on the timetable to recover from, so it works best alongside Engine rather than instead of it.
Broadly, yes: hard efforts, short rests. The difference is the work: sleds, ergs, carries and barbells rather than bodyweight circuits in a studio. Same principle, more transfer.
At REP HYBRID, inside Glo Damansara in Taman Tun Dr Ismail (TTDI). The class is HYROX Sprint. Minutes from Damansara Utama, Damansara Kim, Bandar Utama and Mutiara Damansara, and easy from Petaling Jaya and wider KL.
One athlete deep into a long effort on a rowing erg. Side profile, chest heaving. Sustained work, not explosive.
Wide floor shot mid simulation. One athlete carrying sandbags, another finishing a run, a third at a station.
A lifter under a loaded barbell mid squat. Close, low camera angle, chalk on the bar.
New here? A pack is the better way in, enough sessions to stop feeling new and start seeing what the training does. Or take a single class if you'd rather test the water.
