I want to try 20 Second Fitness risk free for 90 days!

Seeing fast results through quick high-intensity interval training (HIIT) workouts:


20 Second Fitness is scientifically designed to help you reach your weight loss and fitness goals through short, high-intensity interval workouts that exhaust the muscles and burn calories. The program focuses on working out at your maximum effort for 20 second intervals followed by 10 seconds of rest for 4-12 minutes at a time.


20 Second Fitness works by tapping into the rarely used anaerobic energy system with rapid calorie burn and muscle targeting to build lean muscle and boost your metabolism.
