Keep your thighs in check this spring with Reebok’s new toning apparel.

Based on the popularity and success of the EasyTone footwear, Reebok has created EasyTone apparel designed to help tone key muscles while you move. The new line features toning bands that are incorporated into the fabric to create resistance, resulting in increased muscle activation in leg, butt and upper body muscles.

Here’s the deal: the clothes fit close to the body and use compression technology as a delivery mechanism for the unique ResisTone bands, which are based on the bands often used in athletic resistance training.

The bottoms, which include pants, capri pants and shorts, feature a knit basket weave pattern with dual bands in criss-cross pattern around the butt and hamstring. The combination of the placement and the tightness of the bands are designed to help tone the hamstring, quadriceps and butt muscles with every step.

In the upper body apparel, which includes bra styles and short-sleeved and sleeveless shirts, the bands are bonded onto compression fabric around the shoulder blades. Together, the placement and the tightness of the bands are designed to promote greater postural alignment.

Katrin Ley, Head of Women’s at Reebok, said: “EasyTone has been incredibly successful because it taps into the desire that women want apparel and footwear that is designed to help give them added benefits while they move. With the introduction of EasyTone apparel, the first apparel that’s designed to help tone key muscles, Reebok is extending its leadership in the toning category.”

So what are you waiting for?  Celebrities including Anna Paquin, Blake Lively, Hillary Duff, Ashlee Simpson-Wentz, Katy Perry, Kristen Bell, Reese Witherspoon, and Rosario Dawson are already sporting the new line of clothing.
