START WITH A READY-MADE WORKOUT Choose a Tabata routine or a functional fitness circuit, inspect its exercises, and adjust the timing to your needs.

Save separate routines for different training days. BROWSE EXERCISES OR CREATE YOUR OWN Find exercises in the fitness library, read their instructions, and add them to your workout. Create custom exercises with your own name, description, and optional photo or video link. CUSTOMIZE YOUR SESSION Choose exercise icons and colors, rename steps, and arrange your sequence. Duplicate, move, copy, and paste exercises to build routines from steps you have already configured. FOLLOW EVERY INTERVAL See the current exercise, remaining interval time, next step, and time left in the workout. Pause and resume, restart, or move through the sequence. Choose sound cues for your session. KEEP YOUR TIMER IN VIEW Follow your workout with Live Activities on the Lock Screen and Dynamic Island. Use widgets to access your timer.
