Happy New Year! Your motivation is probably at an all-time high — so now is the time to take advantage of the new-found burst of energy.

No gym? No equipment? No excuses. This simple body-weight workout can be done in the comfort your living room (however space-challenged you may be), and the only thing you’ll need is a timer (my favorite is Gymboss) to count down the intervals…and maybe a towel to mop up all the sweat.

The workout itself consists of four circuits of four exercises. Each circuit’s exercises efficiently cover one (or more!) of the following elements: Cardio, Upper Body, Lower Body and Core. If you’re unfamiliar with a move, just Google the name for a list of descriptions and/or demo videos.

It’s an easy way to trick yourself into a quick — yet intense — total body workout and to get that jump-start on 2014’s fitness goals.
