45-minute class

Conditioning: work hard, then breathe. Repeat.

Timed intervals on bikes, rowers, ropes and sleds. The clock sets the rhythm; you choose how hard to go in every block.

How intervals work

Short efforts, planned recoveries

An interval is a set period of work followed by a set period of rest. We use three formats, often in the same class.

40 s on · 20 s off

Rounds

Rotate through four stations. Simple, steady and easy to pace.

WorkRest8 rounds · 8 minutes

30 s on · 30 s off

Pairs

You and a partner swap: one works while the other recovers.

10 rounds · 10 minutesEqual work and rest

60 s · 45 s · 30 s

Ladder

Efforts get shorter as you go, with a full minute’s rest between.

2 ladders · about 9 minutes

Pace options

Three paces in every block. Change whenever you like.

Your coach describes each one before the block starts. Nobody else knows which you’ve picked.

Steady

You can talk in short sentences. A good place to start, and to come back to whenever you need.

e.g. Easy cadence on the bike, half-pace rope waves.

Push

Breathing hard, but in control. You could keep going if you had to.

e.g. Firmer bike resistance, continuous rope waves.

Peak

A short, hard effort you’re glad to finish. Optional, and only for a few rounds.

e.g. Sprint pace on the rower, heavier sled push.

Equipment

What you’ll use

Your coach shows you how to set up and use each piece before the first interval.

Air bikes

Arms and legs together. The harder you pedal, the more resistance.

Rowers

A full-body pull. We teach the stroke in the warm-up.

Battle ropes

Waves, slams and circles. Easy to scale, surprisingly tiring.

Sleds

Push or drag along the turf. Load goes up or down in seconds.

The session

What forty-five minutes feels like

  • 0–8 min. Warm-up and a walk-through of each station.
  • 8–35 min. Two interval blocks with a three-minute reset between them.
  • 35–40 min. A short finisher. Optional, always scalable.
  • 40–45 min. Easy cool-down and stretching while your breathing settles.

Expect to be warm and out of breath, with music on and a coach calling time. It’s energetic, but never a competition.

Conditioning FAQs

Common questions

I’m not very fit. Is Conditioning too much?

Not if you stay on the Steady pace. Many people start there and stay for weeks. You can also take extra rest at any point.

Is there jumping?

Only if you want it. Every exercise has a low-impact version, and your coach will show you both.

How is this different from Strength?

Strength is about lifting with full rests. Conditioning is about keeping moving with short, timed recoveries. Read Strength or Conditioning? for more.

Can I do Conditioning the day after Strength?

Yes, though if you’re new, a rest day or a Mobility class in between helps.
