YOUR DAILYDOSE.

60 minutes. 4 chemicals. One bike.
Led by Rafael Urbay, Ironman athlete.

01 The Method

Four chemicals. One class.

DOSE is the four chemicals your brain releases when you ride hard. Every class is built to hit all four.

  1. D
    01 / 04

    Dopamine

    Your reward chemical. Every climb you push through, you earn a little more.

    Reward · Drive
  2. O
    02 / 04

    Oxytocin

    The bonding one. It kicks in when the whole room moves together.

    Bond · Trust
  3. S
    03 / 04

    Serotonin

    Steadies your mood. You leave calmer and it holds for days.

    Mood · Calm
  4. E
    04 / 04

    Endorphins

    Your body's painkiller. It's why the burn starts to feel good.
