About Forma

Forma is a free workout coach that runs in your browser. A 3D athlete — Leo or Mia — shows every exercise at the right tempo, the muscles it works light up, and a voice counts your reps in 17 languages. You can build a plan for your goal and equipment, train with it, and keep a log on your own device.

Where the advice comes from

Exercise technique, sets, reps and rest times follow the guidance of the American College of Sports Medicine (ACSM), the National Strength and Conditioning Association (NSCA) and public-health advice from the World Health Organization and the CDC. Health-related guides cite their sources at the end of each page.

Privacy by design

There is no account and no sign-up. Plans and workout history stay in your browser's local storage and are never sent to us.

The 3D athletes

The athletes are built from the Universal Base Characters by Quaternius (CC0, public domain) and animated by our own rig, which places hands and feet exactly on bars, benches and the floor.
