Cyclones and crossfit workouts have one thing in common: some of the most brutal ones are named after women. When scientists at Kennesaw State University studied Cindy, one of the fitness brand's benchmark workouts, they found that doing total-body moves agaisnt the clock can burn 1091 kilojules in just 20 minutes. Thats nealry as many kilojules as you'd burn during a typical half hour gym session.
Try the Cindy workout and let me know how you go!
Set a timer on your watch or phone for 20 minutes. Do five chin ups, 10 push ups and 15 squats, in that order. Thats one round. Do as many rounds as you can before the time runs out.
use an overhand grip to hang from a chin-up bar with your arms straight. Pull your chest to the bar. Pause, then return to the starting position.
Assume a push-up position. With your elbows tucked, lower your chest until it's 2-3 centimetres off the floor. Pause, then push yourself back up.
Stand with your feet set slightly beyond shoulder width. Now push your hips back and lower your body as far as possible. Stand back up.
