HIIT & Strength Studio Software Built for High-Performance Growth

CodexFit is studio software designed specifically for HIIT, bootcamp, strength-focused, and performance-oriented businesses where class volume, coach flow, workout variety, and retention matter most. High-intensity studios operate at pace: timetables are tight, coaches rotate frequently, and members expect energy, structure, and progress. There’s no room for clunky systems or manual admin,  and no excuse for missed revenue or lost attendance.

CodexFit keeps operations tight on the floor while giving founders clear visibility and control behind the scenes, so you can focus on workouts, not workflow.

Fill Classes, Reduce Drop-Off, and Protect Revenue

For HIIT and strength studios, revenue is driven by attendance. Every empty spot in a class is lost opportunity, and every broken routine makes retention harder to recover. CodexFit is built to support the full range of sessions these studios run, from high-volume daily classes to challenges, intensives, and limited-run programmes. Everything sits within the same booking and payment framework, which means studios don’t need separate tools or duplicated products to support different formats.

Rather than relying on staff to manually monitor cancellations, waitlists, and no-shows, CodexFit uses behaviour-led automation to protect class fill. Cancelled spots can be re-offered automatically, reminders can adapt based on attendance patterns, and members can be re-engaged before routines slip. The result is fuller rooms and steadier revenue without adding pressure to the team.

Coach and Schedule Management That Keeps Pace

HIIT and strength studios rarely run static timetables. Coaches change, formats evolve, and schedules need to flex without causing confusion. CodexFit gives studios clear visibility across instructors, classes, and formats so changes can be made quickly without breaking booking rules or creating conflicts.

Instructors always know what they’re teaching and when, managers can spot gaps or issues early, and performance can be reviewed by class and by coach. When schedules, attendance, and instructor data are connected, the entire operation stays aligned, even as the timetable grows more complex.

Insight That Actually Informs Decisions

Most studios have access to data, but far fewer feel confident using it. CodexFit focuses on insight rather than information overload. Revenue, utilisation, and attendance trends are visible in one place, making it easier to understand what’s working and where adjustments are needed.

Instead of pulling reports from multiple systems or relying on spreadsheets, studio owners can see how different classes perform, how capacity is being used, and where engagement begins to drop. This makes it possible to adjust schedules, pricing, or formats with confidence, based on patterns rather than instinct.
