Fitness Tracking

Gym owners had no digital way to assign workout plans to members or track their adherence remotely.

Overview

We built a fitness tracking app that connects gym trainers with their members — trainers assign custom workout plans, members log their sessions, and both sides have visibility into progress, adherence, and communication.

The Challenge

Gym owners and personal trainers had no digital tool to assign workout plans, track whether members actually followed them, or communicate between sessions. Members got a paper workout sheet on day one and were on their own after that. Adherence dropped off quickly, and trainers couldn't adjust programs without in-person check-ins.

Our Approach

1

Built workout logging with an exercise library, custom program builder, and session tracking

2

Created progress tracking with measurements, progress photos, and comparison views over time

3

Implemented nutrition tracking with macro calculations and daily logging

4

Added in-app messaging for trainer-member communication and accountability check-ins

Delivered In

Member workout adherence improved significantly compared to paper plans

Trainers report better program adjustments with digital visibility into member activity

Member retention increased noticeably for gyms using the platform

Trainers can manage more clients effectively with the async communication tools

Members used to get a printed workout sheet and we'd never see them again until they cancelled. Now trainers see who's showing up, who's slipping, and can reach out before someone ghosts. Our retention numbers have never been better.
