ROOMS

Train with a real person, in a small group.

A Room is run by an independent trainer around a curriculum they wrote. You work through it week by week, with the group beside you.

  • 1
    A curriculum with a pace

    Modules open on the trainer's schedule, so everyone moves together.

  • 2
    Assignments with feedback

    Submit your work and your trainer reviews it.

  • 3
    Their price, their rules

    Each trainer sets their own Room price and length. Fitulse is the platform.

PULSES

A Pulse is the point you earn for showing up. Show up on consecutive days and it builds a streak, on your own or together with your Room.
