How Bubas Gym Runs Its 15-Year Training System on QuickCoach

What is Bubas Gym and the Bubas Training System?

TL;DR: Bubas Gym is a training facility in Croatia founded by Marko Bubas, an OPEX CCP, CrossFit Level 2 and Precision Nutrition certified coach. He built the Bubas Training System over 15 years and has run it on QuickCoach since the platform's early days, calling it everything he needs for effective trainer-client collaboration.

Marko Bubas is the founder of Bubas Gym and the creator of the Bubas Training System, a movement, nutrition and behaviour approach he has used with gym members for 15 years. His whole method is built around one thing: helping trainers and clients work together well through the entire training process. That is coaching built on functional fitness, strength and conditioning, and nutrition coaching, delivered from one place.

The challenge

How do you support the whole trainer-client relationship?

As the training system grew, Marko needed a dependable way to hold the trainer-client connection together. He did not want to stitch several tools into a stack or hop between programs. He wanted one platform that carried everything required for effective collaboration, so it would fit naturally into his coaching process and cover the essential parts of working with clients.

The choice

Why has Marko Bubas used QuickCoach since its early days?

Marko chose QuickCoach early and has kept it at the centre of the Bubas Training System ever since. The platform brings together the capabilities he needs to work with gym members, without another coaching program running alongside it. That consistency turned QuickCoach into a dependable part of his workflow, one he keeps using as he delivers his system to clients at Bubas Gym. Coaches weighing a first platform often start with the best free coaching software or online personal training software.

Across his time on QuickCoach, Marko has programmed more than 220,000 exercises into his members' plans. His clients complete over 13,100 training plans at a 97% adherence rate, and stay with him for close to 30 months on average.

The result

What does Marko Bubas use QuickCoach for?

It is a trusted coaching platform that supports the Bubas Training System and has earned his long-term loyalty.
