"If you’re not a morning person, you probably don’t have time for a full-on morning workout before hustling out the door. But you want to get your metabolism going strong and get your workout out of the way so it doesn’t get knocked off the agenda later in the day (been there). One elegant solution is Sworkit, which offers circuit training in chunks ranging from five to 60 minutes. At 8 a.m., we’re probably going to opt for a quick five-minute workout (though it’s nice to know we can go longer, if we want).
Workouts focus on strength training, yoga or cardio, all in circuits (hence the app’s name). Once you select the style, you can select a body area to focus on (or go for the full-body workout). For all of the exercises in Sworkit, the only equipment you need is your own body, and the app builds randomized circuit training workouts for you, so your muscles won’t get used to a certain routine.
"Anyone can do this in their bedroom, hotel, or anywhere you can imagine," says Ryan Hanna, a former U.S. Army officer and the founder of Sworkit. Embedded videos in the app will show you the ropes for each move, making the app noob-proof.
Sworkit offers a free version and Sworkit Pro, which goes for $0.99.”
