## User Challenges

Many fitness apps overload users with complex flows and long workouts. People need short, effective sessions that match their strength levels and provide clear device connectivity.

## Key Pain points

### Disconnected Experience

Users often failed to sync their Activ5 device quickly, leading to frustration and abandoned workouts.

### Lack of Guidance

Exercise flows were unclear, making it difficult for users to explore workouts tailored to their strength level.

### Low Engagement

Long sessions discouraged regular use, with many users dropping out before completing their workout routines.

> Our focus was on simplifying health tracking and exercise flows, ensuring that every workout feels personalized and easy to follow.

Users said short workouts fit their daily schedules better and boosted regular app engagement.
