Product Design: Helping Lapsed Exercisers Rebuild a Workout Habit
Company: Meta
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Design a product that helps people who have fallen out of exercising get started again.
```hint Restarting is not starting
Someone who used to exercise already knows how. Think about what made them stop and what makes the first few sessions back feel hard, and design for that gap rather than for a beginner.
```
### Clarifying Questions
- Are we a new company building a standalone product, or adding this to an existing product whose users we can already reach?
- Who are "people" here: anyone who has lapsed, or a specific group such as new parents, people returning after an injury, or former gym members? Or is the segment my choice?
- Does success mean getting someone to a first workout back, or a routine that lasts for months?
- Is there a launch market or platform constraint, such as one country or phone only?
### What a Strong Answer Covers
- A chosen segment of lapsed exercisers, with the reason it comes first
- Why people stop and why restarting is hard, ranked into the pain points worth solving
- Solutions aimed at the restart moment and the first weeks back, prioritized into an MVP
- A north-star metric based on exercise actually done, with guardrails
- Risks specific to this product: injury, shame-driven mechanics, gamed streaks and the safety of meeting strangers
### Follow-up Questions
- How would you know users actually exercised rather than just opened the app?
- Your data shows most users drop off in week three. What would you change?
- How would you serve someone coming back from an injury or illness without giving medical advice?
Overview: A product design interview question asking how you would build a product that helps people who stopped exercising get back into it. It tests segmenting lapsed exercisers, diagnosing why restarting is hard, prioritizing features into an MVP, and choosing success metrics based on workouts actually completed.
