Go! New York: Total Resistance Exercise

Finding time to workout is never easy, but what if you could work up a real sweat at home, in an apartment or any small space? One strap, bright yellow, is all you need to get started.

"Look at this, I'm out of breath already," said student Susie Q. "It only takes a few seconds and, you know, you're just incorporating the bodyweight and just kind of doing exercises that you wouldn't normally be able to work out when you're on the machines."

TRX, which stands for total resistance exercise, is 12 feet of nylon strap that forces you to use your own body weight to literally do hundreds of different types of exercises.

This exercise was actually created by a Navy Seal, and it was meant to be able to do at home, anytime, anywhere.

A class called Body Web at Crunch Gym takes you through the basics. Zuta Gilchriest is the instructor.

"So, it's two straps that you're going to be holding onto either with your hands, or with your feet, and it can be adjusted so that you can perform a wide range of exercises, from squats, to lunges, bicep curls. It's a great way to strengthen your body. It's super fun and it's a great class," she said.

It weighs less than two pounds and can be set up in any room, at home or if you are traveling. Leo Wright is training to teach the class but has been using TRX for a quick workout regularly.

"Well, just everything, it elongates the muscles, strengthens, cardiovascular, this is the whole package. You don't got to go anywhere. And it's portable. It's like this small, put it right in the bag, anywhere you go" he said. "I don't take it home. It is at home, and I do it at home too, in the park, everywhere I go."
