LEGEND consists of 4 parts that you should complete one after another. Between part a), b) and c) you have 1 minute rest.
LEGEND is a classic interval workout that uses the Tabata training method: 20 seconds of work followed by 10 seconds of rest, repeated 8 times. LEGEND starts with part a) 8 Rounds of Burpees (= 20 Sec. Burpees, 10 Sec. Rest), then 1 minute rest followed by part b) 8 Rounds of Lunges (= 20 Sec. Lunges, 10 Sec. Rest), then 1 minute rest followed by part c) 8 Rounds of Sit Ups (= 20 Sec. Sit Ups, 10 Sec. Rest), then 1 minute rest followed by 8 Rounds of Squats (= 20 Sec. Squats, 10 Sec. Rest).
Scaling: You can scale LEGEND by reducing each parts from 8 to 4 rounds.
