HIIT
Set up the timer
A HIIT timer alternates timed effort and recovery. In Workout Timer, you set how long each work and rest interval lasts, how many exercises make up a round, and how often the round repeats.
Choose three movements, then set 40 seconds of work and 20 seconds of rest. Start with three rounds and set a separate round break that works for your pace.
