Chapter 02 · Problem Statement
FitPact’s primary job is to make weekly fitness and nutrition commitments visible, socially supported, and easier to resume after partial adherence or missed commitments.
The initial FitPact audience is inconsistent exercisers of any experience level. They may know what they want to achieve and may already understand training or nutrition, but they repeatedly fall out of exercise and diet habits because those habits are not socially supported.
Existing products often
- Provide generic or authoritative plans.
- Treat planning as the main problem rather than sustained participation.
- Separate exercise and nutrition.
- Depend almost entirely on self-motivation.
- Use punitive streaks, surveillance, or shame.
- Fail to give a trusted person a clear, constructive role.

one pact
FitPact connects:
The user
Owns their health decisions and follows a weekly plan.

The words
do the work
8 terms carry the whole product. They replace the supervisory vocabulary the category defaults to.
- Pactmate
- The trusted person in a pact. It replaces “supporter” and “accountability partner.”
- Pact
- A shared, fixed-term commitment between two adults.
- Pact Lane
- One member’s personal commitment inside the pact. A lane contains workouts, nutrition, or both.
- Pact Pulse
- The structured weekly check-in.
- Boost
- A predefined encouragement or reaction.
- Reset
- A proposed change to an active weekly plan.
- Co-sign
- A Pactmate’s approval of a Reset.
- Finish
- The successful arrival at the fixed pact end date, regardless of perfect adherence.

Chapters 03 & 05 · Vision, principles, non-goals
What it stands on.
What it refuses.
FitPact should become a shared fitness-planning workspace in which users make realistic weekly commitments and Pactmates help them keep those commitments without becoming coaches or authorities.
The experience should feel
- Supportive
- User-directed
- Practical
- Flexible
- Nonjudgmental
- Fast
- Transparent about AI limitations
- 3.1
User bodily autonomy
The user can always pause a plan, stop an activity, revoke access, or end a pact. No Pactmate co-sign is required for these safety and autonomy actions.
- 3.2
Social commitment
When an active pact exists, activating a replacement plan is called a Reset and requires the Pactmate to co-sign it. Co-signing creates a deliberate shared recommitment; it does not force continued exercise or dietary behavior.
- 3.3
Curated before generated
Exercises, workout templates, meal templates, and recipes come from reviewed catalogs. AI selects, combines, explains, and proposes adaptations to this content rather than inventing unconstrained workouts or recipes.
- 3.4
Editable and explainable
Plans are editable before activation. Significant suggestions include concise reasoning and assumptions.
- 3.5
Realistic over optimal
Adherence, schedule, preferences, access, and sustainability take priority over theoretical optimization.
- 3.6
Partial effort counts
Workout and nutrition adherence are measured separately. Partial completion receives visible credit and is not converted into failure.
- 3.7
Support without surveillance
Pactmates receive the agreed plan and adherence visibility but cannot edit logs, prescribe behavior, or freely message through FitPact.
- 3.8
Safety before intensity
FitPact blocks plan assembly when reported information indicates a potentially life-threatening condition or a situation that requires individualized medical advice.
