Did you know that Fila USA released workout pants that are supposed to increase muscle workout by 50%? The manufacturer claims that these pants were “designed to increase muscle exercise, which improves the efficiency as well as recovery of an existing workout.” These pants do offer more support which means an instant butt lift and better shaping of the hips and thighs, but do they really make you exercise harder? With this concern in mind, the American Council on Exercise commissioned a study to find out if the compression provided by the apparel could actually increase the intensity of a workout session. Unfortunately, the resistance offered by the new workout pants is not enough to provide significant results. So, if you really want more muscle tone in your legs, you are better off including more squats and lunges in your routine than simply buying an exercise outfit.
