After the great success of our first FunTone CD now follows the second release. Enjoy a dynamic warm up followed by 16 interval tracks. Thanks to the significant special effects such as countdown & gong, nothing stands in your way for your optimal interval training. Interval: 30s Intro / 4 x 45s Power / 15s Pause The advantage of these mixes: an instructors voice counts and announces the start of exercise and rest time. Optimal motivational support!
