The Adherence-First Exercise Rule evaluates a workout by whether the person will actually repeat it, not only by its theoretical physiological benefits. Begin with exercise formats that can support the relevant fitness goal, then favour the option you genuinely enjoy enough to practise often. The mechanism is straightforward: enjoyment lowers resistance, lower resistance improves repetition, and repeated training produces more value than an ideal programme that is consistently skipped. The rule does not require every session to feel appealing. Cohen and Kayvan both acknowledge that some days still require pushing through reluctance. The distinction is between occasional low motivation and chronic dislike of the activity itself. The output is a sustainable default—such as dancing, boxing, or strength training—that can survive beyond a short burst of willpower.
Origin
Liron Kayvan answers the question of the best exercise by prioritising the activity a person will actually do. Jennifer Cohen reinforces the rule with enjoyable cardio such as dancing.
Core principles
- 01A theoretically optimal workout has little value if it is repeatedly avoided
- 02Enjoyment increases the chance of consistent practice
- 03Consistency matters because fitness requires repeated effort
- 04Occasional reluctance does not mean the activity is a poor fit
How to run it
- 1
Define the goal
Clarify the broad outcome the activity must support, such as strength, cardiovascular fitness, mobility, or general consistency.
Pro tip Keep the goal broad enough to allow more than one valid activity.
- 2
Generate enjoyable candidates
List exercise formats you can access and would be willing to repeat, including playful or skill-based options.
Pro tip Consider dancing, boxing, sport, or classes rather than limiting the list to conventional gym machines.
- 3
Choose for repetition
Select the option that meets the goal well enough and that you are most likely to perform consistently.
Watch out Do not optimise minor programme details at the expense of adherence.
- 4
Test the habit
Repeat the activity over several weeks and observe whether it remains a realistic default rather than a novelty.
Pro tip Distinguish one reluctant day from a recurring pattern of avoidance.
- 5
Adjust without quitting movement
If the format repeatedly fails the adherence test, replace it with another enjoyable option that still serves the goal.
Watch out Changing the format should not become an excuse to stop exercising altogether.
In the wild
Cohen points to dancing as cardio she enjoys even though she does not consider herself an excellent dancer. The activity supplies cardiovascular movement while enjoyment makes it more attractive than a prescribed format she would avoid.
→ Cardio becomes an activity the person is more willing to repeat.
A person repeatedly skips solitary treadmill sessions but looks forward to a boxing class. They switch their default cardio to boxing while retaining strength work, choosing the format with the stronger chance of consistent attendance.
→ Weekly exercise becomes more consistent without abandoning the fitness objective.
Common mistakes
Chasing theoretical perfection
A highly optimised programme cannot work when dislike causes the person to skip it repeatedly.
Expecting constant motivation
Even a well-matched activity sometimes requires starting despite not feeling in the mood.
Ignoring the actual goal
Enjoyment guides the choice among useful activities; it does not make every enjoyable activity suitable for every objective.
Is it for you?
Best for
It is best for people building a sustainable fitness habit or repeatedly abandoning prescribed routines.
Not ideal for
It is not ideal when medical rehabilitation or a specific competitive goal requires prescribed training regardless of preference.
From the transcript
“the best exercise is a thing that you're actually going to do versus what someone tells you to do”
“you're only going to do it a lot if you enjoy it”
“there are definitely times where you have to you're not in the mood”
