Invented by Sandra Bonacina
\nDeveloped by Sandra Bonacina and Viktor Denoth<\/p>\n

\u200bLarge gym balls are popular for physical therapy training, but they need a lot of space, are relatively soft and unresponsive to fix body parts well, and are difficult to transport. Instead, Sandra Bonacina was looking for a simple, symmetrical arch.<\/p>\n

When the Center for Rappelling, Climbing, and Mountaineering (Kletterzentrum Gaswerk Schlieren), designed by Viktor Denoth and his ASVZ team, was built in Schlieren, Switzerland, in 1994, Denoth discovered curved plywood sheets \u2014 several layers of wood glued together \u2014 that were used to create overhangs on steep routes. Sandra Bonacina and Viktor Denoth calculated the optimal radius using studies of the spine\u2019s natural lumbar lordosis and soon built the first multifunctional training-and-therapy bow: the T\u2011BOW\u00ae.<\/p>\n

\"\"<\/p>\n

\u200bThe University of Z\u00fcrich and the Academic Sports Association Z\u00fcrich (ASVZ) were offered the opportunity to introduce the T-BOW\u00ae to test it as a means of circuit training and as a tool for strengthening core muscles in the room of gymnastics. Since 1996, the bow has become a widely used device for strengthening the abdominal, back, and lateral trunk muscles.<\/p>\n

\u200bSandra Bonacina wanted to do more with this instrument and had the idea of adding holes in the sides of the bow so that she could incorporate resistance bands into training exercises. Thus the whole body could be trained with more alternatives.<\/p>\n

\u200bLikewise, he also wanted to use both sides of the arch; one side as a “step” for “cardio” and “trunk toning and mobility training”, and the other side as a seesaw for balance training and swing coordination. Viktor Denoth made a non-slip cover for the concave side of the bow. Now the bow became versatile and multifunctional for training strength, endurance, balance, speed-reactivity and flexibility.<\/p>\n

\u200bThe Prototype had been created and was ready to be patented.<\/p>\n

The T-BOW\u00ae was developed over more than 10 years (1994-2006) by Sandra Bonacina in collaboration with Viktor Denoth, both university professors at the Institute of Movement and Sports Sciences at the University of Zurich.<\/p>\n

Since 1996 it has been used in the fitness and gymnastics halls of the University of Zurich as a material for strengthening the trunk muscles and for training the overall balance of the back.<\/p>\n

\"\"<\/p>\n

In 2005 an advanced phase of the meticulous and intensive development of the multifunctional application possibilities of T-BOW\u00ae is completed. Sandra Bonacina experiments with collaborating students from the University of Zurich the multiple ways of implementing the T-BOW\u00ae in the field of Fitness and Health, and its use is effectively consolidated in sports and fitness centers throughout Switzerland.<\/p>\n

\u200bOn the other hand, based on the original T-BOW\u00ae built from natural wood in 1995, a synthetic fiber prototype (high-density polyethylene) is designed that has the advantage of extraordinary resistance to high loads, its ease of keeping hygienic and clean , and its greater practicality to be stacked safely.<\/p>\n

THE STORY OF THE T-BAND<\/h5>\n
T-BOW\u00ae Elastic Bands<\/h5>\n

Invented by Viktor Denoth \u00b7 2004
\nDeveloped by Viktor Denoth and Sandra Bonacina<\/p>\n

Sandra Bonacin wanted the possibility of varied strength training with individual levels and gradual increases in performance. Two meters of elastic bands are enough to thread through the holes in the middle of the sides of the bow and have two separate bands on each side. So you could take one band for an easier workout and two bands for a stronger one.<\/p>\n

\"\"<\/p>\n

Viktor Denoth then perfected the elastic bands so that more than one or two could be introduced into training programs. A strong tape below the T-BOW\u00ae connected three 1 meter tapes on each side, which were threaded through the holes in the middle of the sides.<\/p>\n

Viktor Denoth&#39;s idea to recycle old tennis balls holding three cushions was a decisive success. Since then the durability of the bands is much greater. Another great advantage is that broken single belts can be easily replaced, thus reducing the cost of renewing them.<\/p>\n

For group fitness sessions, where quick changeover from one exercise to another is important, it is best to use the professional T-Bands, one single and one double attached to a tennis ball. They are bicolor: 1 meter orange and 2 meters blue, forming a loop. In this way it is possible to quickly change from 1 to 2 or 3 bands, varying the levels of force required.<\/p>\n

Movement \u00b7 Vitality \u00b7 Fun<\/h5>\n

\u201cWith the T-BOW\u00ae we have a wonderful material to make people move. Movement means to be alive and healthy. We feel fortunate to bring health and stress reduction with high quality programs to train all aspects of fitness and deep joint stability. Thus many people have fewer back problems using the T-BOW\u00ae. It is fantastic that we can use it in all ages and groups. I am convinced that the T-BOW\u00ae will be a reference throughout the world for its high quality proven for years\u201c.<\/p>\n
