Periodized programming
Build multi-week, periodized programs with the AI builder and a 500+ movement library, then adjust every set.
For sports performance & S&C
Software for sports performance & strength and conditioning
Built for athlete development: program periodized training, track progress, and run group and individual sessions for teams and athletes of every level.
Sports performance and strength-and-conditioning facilities have needs most fitness software ignores: real periodized programming, athlete tracking over a season, and a mix of team sessions, small groups, and individual athletes. Class-box software wasn't built for athlete development, and generic schedulers can't program a training block.
Flex is built by a CSCS-credentialed coach. Program multi-week periodized blocks, track each athlete's PRs and progress, and run group and individual sessions — with payments and a website included.

The day-to-day headaches Flex is built to remove.
Class-box software can't program
Tools built for group fitness can book a session but can't write a periodized training block. Flex does both.
Athlete progress lives in spreadsheets
Track PRs, testing, and body metrics per athlete over a full season, with charts athletes and parents can see.
Mixed session types
Run team training, small-group performance, and 1-on-1 athletes from one schedule.
Youth and parent communication
Parents book and pay through one portal, and reminders keep busy families on schedule.
