How it works
From program to completed workout. Three simple steps.
Set up your client's training once. Keep everything connected from the first assignment to their next completed session.
- 1
Build a program
Create workouts from the exercise library, adjust sets, reps and rest, and organize the sessions your client needs.
- 2
Assign it to a client
Share the program in Fitler. Your client opens their workouts without searching through messages or files.
- 3
Follow the training
Clients log sets and weights as they train, and you see completed sessions, so your next conversation starts with what actually happened.
One place for your coaching
Your programs, clients and conversations. Together.
Less jumping between tools. More clarity about the workouts you deliver and what your clients complete.

Fitler runs in the browser on your phone, tablet and computer — open web.fitler.app and sign in, nothing to install. Android and iOS apps will follow; leave your email further down the page and we’ll let you know when they’re ready. Trainer and client use the same account system with different roles.
What does training progress mean in Fitler?
