OneGym is a comprehensive fitness management platform that combines equipment guides, workout tracking, staff communication, and AI assistance into a single, seamless experience. Built on Cloudflare's edge network for maximum performance and reliability.

The Challenge

Modern gym members expect instant access to equipment information, the ability to track their progress digitally, and fast response times when they need assistance. Traditional gym management systems were either too expensive, too complex, or lacked the modern features that today's tech-savvy members demand.

Key Problems Identified:

  • Members waiting for staff to explain equipment usage
  • No digital workout tracking or progress visualization
  • Staff couldn't monitor equipment issues in real-time
  • No 24/7 support for basic fitness questions
  • Existing solutions cost $500+/month per location

Our Solution

We built OneGym as a cloud-first platform leveraging Cloudflare's edge network for lightning-fast performance worldwide. The system was designed with three user types in mind: members, staff, and administrators.

Equipment Library (16 Items)

Complete equipment database with categories, video tutorials, step-by-step instructions, and safety tips. Members can browse by category or scan QR codes on equipment.

Technologies: Cloudflare D1 Database, Video Embedding, QR Code Integration

Workout Tracking & Progressive Overload

Members can log sets, reps, and weight for each exercise. The system automatically tracks progress over time and displays visual charts showing strength gains.

Technologies: Chart.js, Real-time Calculations, Historical Data Analysis

Staff Alert System

Real-time communication between members and staff. Members can request help from equipment pages, staff receive instant notifications, and can manage alerts through a dedicated dashboard.
