Beskrivelse
This 140+ page book has been approved by TWiEA - The World Isometric Exercise Association (www.TWiEA.com). Currently, the entire range of books written by Brian Sterling-Vete and Helen Renee Wuorio about the Bullworker, isometrics, and other related forms of exercise are the only books to have received this approval together with TWiEA's 5-Star Rating. The Doorway to Strength(TM) shows how a simple door, doorway, and doorframe can be used to create a multi-gym of exercises using the amazing Iso-Bow(R) exerciser and the ISOfitness(TM) exercise system. The Doorway to Strength(TM) demonstrates how to perform a host of powerful and effective exercises such as the door leg press and shoulder power push, together with many other exercises to work all the major body parts. There are arrows clearly showing the direction in which the force should be applied. The Iso-Bow(R) exerciser is probably the world's smallest and most powerful portable total-body exerciser. The Iso-Bow(R) is so compact even that a pair of Iso-Bows(R) can easily fit into the pocket of an average pair of jeans. However, even just one Iso-Bow(R) can deliver the perfect level of workout intensity for a beginner or an advanced athlete, and with no adjustment necessary. The ISOfitness(TM) exercise system aims to deliver more results, in less time, and with less exercise than any other exercise system. Required Extra Equipment: 2 x Iso-Bows(R) (preferably 4), a solid door wedge/stop.
