HIIT and Strength Studio Software That Keeps Every Class Full

CodexFit is studio software built for HIIT, bootcamp and strength studios, where class volume, coach flow and member progress matter most. From spot bookings and waitlists to intro offers, memberships, challenges and opening your next location, CodexFit keeps the floor running at pace without adding admin or juggling separate systems.

"Rather than forcing our business into a rigid workflow, CodexFit gives us the tools to build systems that fit the way we operate and the experience we want to create for our members."

Joshua Preston, Co-founder β€” Sala Studio, Auckland NZ

Bookings That Keep Up With Your Floor

HIIT and strength studios run at pace. Timetables are tight, classes fill fast and every station or rack is a booking your coaches have planned around.

With CodexFit, members book their class and choose their spot in a few taps, on your website or in your app, and can bring a friend along. Check-in is quick, so coaches start on time and the energy stays high from the first round.

Behind the scenes, CodexFit protects every spot. When someone cancels, it's offered to the waitlist automatically, and timely reminders cut down no-shows. Your team spends less time on admin and more time coaching.

Memberships, Packs and Intro Offers Built for How Members Train

Some members train five days a week, others drop in when work allows. CodexFit supports unlimited memberships for regulars, class packs and credits for flexible schedules, intro offers for first-timers and drop-ins for occasional visits, all in one connected product system.

You decide what each session is worth. A small-group strength session or a signature class can cost more credits than a standard one, and access rules control which memberships can book which formats. Reward your unlimited members with perks like earlier booking windows. As your timetable grows, your pricing grows with it.

HIIT, Strength and Bootcamp in One Connected System

Most high-intensity studios run more than one format. HIIT and conditioning classes sit alongside strength sessions, bootcamps, small-group training, multi-week programmes and community challenges.

CodexFit treats every format as part of one connected system. Whether it's a 45-minute HIIT class, a beginners' strength course or a month-long challenge, everything runs through the same booking, payment and member framework. Schedules stay clear, reporting stays consistent and members get one simple experience across every class and location.

Messages That Keep Members Showing Up

High-intensity training is built on momentum, and your communication should keep it going. CodexFit gives you full control over every message, so it's written in your voice, sent at the right moment and feels personal rather than automated.

The CodexFit Automator responds to real member behaviour. Build workflows using 30 triggers, 177 condition attributes, 15 filters and 23 actions, or describe what you want and let FitBot build it for you.

A nudge when an intro-offer member books their third class. A shout-out when someone hits their 50th session. A personal check-in when a regular goes quiet for 16 days. A challenge that counts every class and unlocks rewards along the way. Small moments that keep members coming back.
