When I first heard about the 7-Minute Workout, an app that promises to grant you the benefits of a sweaty bike ride and a trip to the gym in just a few minutes, I thought it was all hype.
But as it turns out, the app actually, well, works you out.
I tried it for the first time last year and I'm still hooked, so I recently got in touch with Chris Jordan, the director of exercise physiology at the Johnson & Johnson Human Performance Institute and the person behind the "Johnson & Johnson Official 7 Minute Workout," to get some insight into how it works.
For me, the app is perfect on the weekends, when I can't make it to a yoga class, or as something fun to do with a friend at home.

First things first: The entire workout really takes just 7 minutes. Initially, I was skeptical I could accomplish this much in such a narrow time frame.

It consists of 72 different exercises like jumping jacks, sit-ups, and push-ups. Ten of them require nothing but your own body (you'll need a chair that can support your weight for the others). The latest version of the app lets you do each exercise along with Jordan.

To do my workout, all I used was a yoga mat, the hardwood floor of my office, a wall, and a stool.
