The three main features in the structure of the My Back Booster Shirt are:
1. Back and Neck Support – to fit into your spine back and neck curve. It is also padded with high quality foam to add this bounce-ability when you hit the mat at the beginning of the sit ups, it bounces you back very much like a good running shoes when you land on the asphalt. The natural recoil of the shoes help propel you in the opposite direction.
2. Lumbar Support – is the holy grail feature of the My Back Booster Shirt. It fits your lumbar spine like a glove fits your hand. It provides its maximum support to the lumbar spine very much like the arch support in a good running shoes as it lifts and support your arch and prevent it from collapsing during the motion of sit ups. You have to try it to believe it. Your back will definitely thank you for finally providing it with the needed support.
3. Back Support Cushion – this comfortable cushioning will provide support of the whole upper body to allow you to do many sit ups without the strain of the back due to direct contact of the spine on the flat hard floor. This cushioning provide the most comfortable sit ups you can ever do.
