It is a well know fact that celebrities have lots to money and can afford things that the rest of us can on dream about doing. It would be no surprise that many of these celebrities have there own home gyms usually in one of the multi-million dollar mansions that they use. They have home gym which are fully equip with the latest gym equipment available on the market such as interlocking foam mats. Such resources are necessary to be able to maintain the kind of physiques necessary to be Hollywood stars.
Having personal trainer and the latest training equipment is not all that these Hollywood celebrities having in their home gyms. But having interlocking foam mats is absolutely necessary if they are to maintain the vigorous training needed to star in more films. If someone like Mat Damon were to have a home gym it is almost certain that he would have gym mats of some kind to lessen the impact or hard training. It would not be surprising it these were interlocking jigsaw mats as jigsaw mats are a very practical kind of training mat.
