Flexi-Bar: The best workouts with the ingenius vibration training tool 

The FLEXI-BAR, a dynamic bar of about 1, 50 metres length with a handle in the middle, is a multi-functional exercising device that can activate all parts of the body. Small, rhythmic movements set the bar into swinging modes and transfer these on very different groups of muscles, tendons and joints, but particularly the core muscles. In this book the modes of action, specially developed exercises and broad ways of use of the FLEXI-BAR are illustrated. It supports strength, endurance and coordination, stabilises the spine, improves the posture and prevents back pain. With over 200 pictures.
