Overview

GymCity is a modern fitness technology platform founded by Sarwar Hossain to solve operational and growth challenges faced by gyms and personal trainers.
CodersBucket Ltd. (CBL) worked as the core technology partner, responsible for architecture, product development, and platform evolution — from an initial mobile app idea to a full-scale SaaS and personal trainer marketplace serving users across multiple countries.This case study demonstrates how CodersBucket supports founder-led products, adapts to market signals, and builds technology designed for scale.

The Challenge

The fitness industry often operates with fragmented tools and manual processes.

Fragmented Gym and Personal Trainer Operations

Gyms and Personal trainers were using multiple disconnected tools, making operations inefficient and hard to manage.

Manual spreadsheets for member tracking
No centralized system for attendance and billing
Poor data visibility and reporting

Lack of Tools for Personal Trainers

Personal trainers didn’t have a structured system to manage and grow their business.

No proper client management system
No way to track workouts, diet, or progress
Heavy dependency on social media for client acquisition

No Unified Platform

Existing solutions were either gym-focused or outdated, missing a complete ecosystem.

No support for both gyms and trainers together
Lack of flexibility and scalability
No marketplace or discovery feature

Limited Growth & Monetization Opportunities

There was no system to help trainers or gyms grow beyond their physical presence.

No digital visibility for trainers
No lead generation system
No structured onboarding for new clients
