| Component | Question to answer | |-----------|--------------------| | Independent variable (what you change) | One action only. | | Dependent variable (what you measure) | A number or completion rate. | | Duration | Short (3–14 days). | | Success criteria | Clear, binary (yes/no, done/not done). |
Rule: Change only one variable per experiment.
Christine documented the process publicly, not as a “look at me” moment, but as a case study in behavioral change. Here is how she broke it down:
Before starting, write down a single-sentence hypothesis. Phase 2: Set the Experiment Variables | Component
Template:
“If I [specific action] for [time period], then I expect [measurable outcome] because [reason].”
Example:
“If I prepare my gym clothes the night before for 5 days, then I will complete 4 morning workouts because I reduce decision fatigue.”
| Mistake | Fix | |---------|-----| | Changing multiple variables | Isolate one change per experiment | | Running experiments too long (weeks/months) | Keep under 14 days | | Ignoring the data because you “feel” it should work | Trust the log, not the hope | | Not writing the hypothesis down | Writing forces clarity |

Christine Envall, a Pilates instructor, online coach, and mother of four, decided to run an experiment. Not just to change her physique, but to test a radical hypothesis:
“If I change my identity first, will my body have no choice but to follow?”
The answer, as tens of thousands of her followers have watched unfold, was a resounding yes.
Here is the story of the growth experiment—and the three powerful lessons you can steal for your own life today.
