Scottsdale, AZ (PRUnderground) November 11th, 2026

Semi Private Pro, a training software platform founded by Tim Lyons Jr. and Zach Columbia, is helping personal training gyms deliver individualized workouts to multiple clients within the same coached session. The platform supports an approach the company calls Hyper-Personalized Training at Scale, giving gym owners a system for adapting training to each client while maintaining a consistent coaching experience.

The platform grew out of the founders' experience operating Legacy Personal Training in Scottsdale, where managing individualized programs across a busy training floor presented daily challenges. Lyons is the founder of Gym Business Coach and Legacy Personal Training, while Columbia brings more than a decade of experience managing semi-private training operations and developing programming systems. Their combined experience shaped a platform built around the practical needs of gym owners, coaches, and clients.

At the center of Semi Private Pro is its Movement Matrix, which connects a gym's programming to each client's assessed movement abilities. Coaches build a master program, and the software assigns appropriate exercise progressions or regressions for individual clients. This allows people with different abilities to train alongside one another while following workouts matched to their needs. Coaches can make adjustments during sessions, giving gyms a repeatable way to deliver personalized training while reducing the need to write every client's workout from scratch.

"The opportunity is not to make the class smaller. The opportunity is to make the training personal again," Lyons wrote in an article explaining the approach. His emphasis is on giving each client a clear training path that coaches can deliver consistently. Making that path visible helps clients understand how their program relates to their abilities, what they are working toward, and how their training progresses over time.
