Q: When I first heard about the 7-Minute Workout  an app that promises 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  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.

The idea of a workout you can do in minutes was originally envisioned by  Jordan   an exercise physiologist. Here is personal trainer and study partner  Brett Klika  demonstrating one of the workouts. Sources: American College of Sports Medicine's Health & Fitness Journal  YouTube
The concept behind the workout is interval training â short  intense periods of exercise broken up by brief periods of rest.  Jordan  told me  he  based the workout on  his  experience as a fitness consultant for the US Air Force in Europe.

"High-intensity interval training can provide similar or greater benefits in less time than traditional longer  moderate-intensity workouts  " Jordan  said.
