Interview Prompt
We're building a fitness app where users log workouts. Each workout has exercises with sets and reps. We need to track progress over time, like 'how much can this user bench press now vs. 3 months ago?' Design the data model.
Summary
Reps, sets, streaks, and personal bests. Gym rats love their stats.
