HIIT

How it works

A 10-second countdown leads into 17 rounds. Work for 120 seconds on each movement, rest 15 seconds between movements and 20 seconds between rounds.

Take the first round easy. Set a steady pace you can sustain and take extra breaks as needed. Use a stable, non-slip step about 4–8 in (10–20 cm) high.
