At its core, the FitOn app provides a continually updated array of workouts, including more than a dozen live-streamed daily (via Byrdie). Classes range from low to high intensity for any level — whether you're a beginner or an expert. You can filter workouts and classes for length and muscle groups, with exercises catered to ability with some routines that can be done sitting or lying down (via The Fit Careerist). Workouts include cardio, strength, toning, HIIT, Pilates, yoga, and stretch routines, in addition to dance and barre routines (via FitOn). There are also classes on weightlifting, agility, kickboxing (with or without equipment), Zumba, ballet burn, cardio dance, and meditation.

The app includes workouts from exclusive celebrity trainers, including dancer Julianne Hough, who teaches her KINRGY routine that features a blend of dance, strength, and meditation. Other instructors include "Queer Eye"s Jonathan Van Ness and fitness instructor Christine Bullock.

When you sign up to the app, you'll be put on their "Kick Start" program, which provides you with "weekly recommended workouts" (via FitOn). Trainers will also adapt sessions to "match your desired level of intensity," with new classes added every month "to keep up with the latest fitness trends and provide fresh new content" (via FitOn).
