With the latest from Reebok to special shaping tights and leggings from a newer brand called ShaToBu, it seems like more and more these days activewear companies are trying to make apparel work for you. Not as heavily marketed as Reebok, but first out in the gear this summer, the "Body Toning System" from Fila. Fila claims its new pants and tops add a 50 percent increase in muscle workouts with 41 percent more support than average gear.

"What we did is we looked at the body and how the body works and how it moves and decided where to put these strategically placed double layers of fabric," said Executive Vice President of Business Operations for Fila Jennifer Estabrook. "So what happens is the effect is two-fold. The first thing is it holds you in and actually the pants immediately make you look one size smaller. The added benefit is because of the compression of the fabric it works your muscles."

Undergarments from ShaToBu are supposed to have a similar effect. The way they've made their shapers is they've actually built in two resistance bands into each leg and the company equates that to about five extra pounds of resistance on you. So by the end of the day you're really feeling it.

"There's scientific proof to the face that this really does work. When you're walking, when you're doing everyday things like walking up stairs or going to the office you're burning up to 12 percent more calories when you wear this item," said Bloomingdale's Fashion Accessories Director Brooke Jaffe.

NY1 was curious to see how well these items really work, so we took some of the gear to physical therapist Danielle Napolitano at Finish Line Physical Therapy. Napolitano says while the gear likely won't give you the regular resistive force of strength training that you really need, it could be a a great supplement to training.

"The shaper is great for postural awareness and to give feedback to your muscles that will provide strength and give you some support," Napolitano said. "It's great also great for compression. This will allow your muscles to recover any lactic acid left in your body and to help with circulation."

Experts say just like those special shaping, toning, and burning shoes you see everywhere, you can definitely expect to see much more of the activewear category hitting the market in months to come.
