How to choose your level

All new templates use 30 seconds of work and 10 seconds of rest. Beginner uses simpler movements and fewer rounds; intermediate and advanced add movement complexity and rounds. These labels describe the routine, not your fitness. Start with the easier option when unsure, change any movement and extend recovery as needed. Increase pace gradually; high intensity depends on your effort.

Your default warm-up is 8 different movements × 15 seconds (2 minutes), and it can be skipped or extended. The cooldown is editable. Warm-up and cooldown guidance ↗
