Скачать или смотреть Brutal 5 Minute HIIT Challenge: Assault Bike & Ski Erg.

Think you're fit? Try this 5-minute HIIT challenge. This is a rapid-fire circuit designed to test your mental and physical limits. We are combining the most difficult cardio machines in the gym—the Assault Bike and the Ski Ergometer—with explosive bodyweight moves like High Jump Rope and Mountain Climbers.

The goal is to maintain maximum intensity for the entire duration. There is very little rest involved, only active recovery like Walking and Stepping on the Spot. This is the perfect finisher for your lifting session or a quick workout when you are short on time. Watch the video to see the pacing strategy and try to beat my calorie count. Warning: This one burns.
