Muscle Trainer Original

There is a metallic sphere sealed inside of Muscle Trainer that gives the shoe an appropriate amount of weight. Walking while wearing Muscle Trainer increases the bio-load on the body compared with walking in ordinary shoes, which raises the level of energy consumption.
In actual Muscle Trainer walking tests, subjects show an increase of approximately 25% in both heart rate and oxygen intake compared with ordinary walking. That means you can consume more body fat and other energy sources by simply slipping on a pair of Muscle Trainer shoes and going for a walk. Just about everyone can expect to see the effects* in preventing obesity and slimming down.
*Effects vary from person to person.
