The rule makes adherence the first selection criterion for exercise. Compare available workouts by the likelihood that you will repeatedly attend, not by which one appears most intense or efficient. Cohen argues that the activity you hate least is the one that can work because you will actually do it. Berger's regular F45 attendance illustrates the mechanism: he values the instructors, the efficient in-and-out format, and the energized feeling afterward. Repetition then produces fitness benefits and can encourage other good choices. Once attendance is stable, duration or intensity can increase. This reverses the common order of operations: rather than selecting the optimal workout and hoping motivation follows, select the sustainable workout, establish consistency, and optimize later.

Origin

Cohen contrasted a sustainable daily F45 routine with a more intense Barry's Bootcamp plan that would fail if the person hated it and stopped attending.

Core principles

  • 01Consistency beats theoretical intensity
  • 02Enjoyment lowers the cost of repetition
  • 03A workout only works when you actually do it
  • 04Positive after-effects reinforce other good choices

How to run it

  1. 1

    List viable formats

    Identify exercise options that fit your access, health, schedule, and preferences.

    Pro tip Include short classes or simple routines, not only high-intensity programs.

  2. 2

    Rank for tolerability

    Ask which option you resist least and can realistically repeat each week.

    Watch out Do not let prestige or difficulty substitute for adherence.

  3. 3

    Stabilize attendance

    Repeat the chosen workout on a consistent schedule until showing up becomes normal.

    Pro tip A good rapport with instructors can make repetition easier.

  4. 4

    Track the after-effect

    Notice energy, mood, and subsequent choices after training. Use those immediate benefits as reinforcement.

  5. 5

    Optimize second

    After consistency holds, add duration, intensity, or progression without breaking adherence.

    Pro tip Increase one variable at a time.

    Watch out Do not upgrade into a routine you will avoid.

In the wild

F45 over the harder class

Berger consistently attends F45 and appreciates its instructors and efficient format. Cohen notes that prescribing a more intense Barry's Bootcamp routine would be counterproductive if he hated it and stopped going. His repeatable F45 habit is more useful than an optimal plan he would avoid.

The sustainable class supports regular activity, better energy, and other positive choices.

Common mistakes

Optimizing before attending

The hardest or most efficient program produces nothing if you repeatedly skip it. Establish attendance first.

Increasing too soon

Adding duration or intensity before the routine is stable can raise resistance and break the habit.

Is it for you?

Best for

It is best for people who struggle with consistency or feel pressured to choose the hardest workout.

Not ideal for

It is not ideal when a clinician or coach requires a specific rehabilitation protocol.
