Short answer
Lazyweb Research detected 16 distinct experiments at JustFit (July 2026), and all 16 touch the paywall. source[1] In the CTA dataset JustFit runs 11 paywall CTA experiments, but only 3 changed the CTA text — an offer-weighted paywall program. source[2] These are observed before/after variations with inferred rationale, not company-confirmed A/B tests.
All 16 detected JustFit experiments are on the paywall; only 3 of 11 CTA tests changed the button (July 2026).

The finding
Lazyweb Research detected 16 distinct experiments at JustFit, all 16 on the paywall. source[1] In the CTA dataset it runs 11 paywall CTA experiments, only 3 of which changed the CTA text. source[2] JustFit is a pure-paywall fitness experimenter that iterates the offer and layout far more than the button copy.
How it compares
JustFit's 3-of-11 CTA-text-change rate places it firmly in the offer-weighted cluster with Peloton (3 of 12) and Impulse (1 of 14).
How to apply it
JustFit is a benchmark for a fitness paywall that leaves the CTA copy largely fixed (3 of 11) and tests the offer instead. If your fitness app fixates on button wording, JustFit reinforces the pattern — seen across Peloton and Impulse too — that offer structure is where this category concentrates its testing. source[2]
Caveats
All figures are observed variations with LLM-inferred rationale, not company-confirmed A/B tests — no lift is measured. source[1] CTA claims use the 795-experiment CTA dataset. source[2]

Methodology
Universe: 16 distinct JustFit experiments (11 CTA experiments) within 4,814 detected diffs / 795 CTA diffs, July 2026. Extraction: LLM-inferred rationale on observed variations. Caveat: detected variations only, never confirmed A/B tests.
