No Time to Train? Try this 16 Minute Workout

You may not be able to carve out time to get to the gym, but anyone can scrape together a spare 16 minutes (thats probably faster than it takes you to pack your gym bag!) This fast, furious, full body workout takes no equipment and you can do it in just a few square feet of space. The key here is do. not. stop.Do as many of each exercise as you can for 1 minute before moving on to the next. Keep track of how many reps you do the first round and make that your goal for all 4 rounds. Repeat the circuit 4 times and try not to puke. 1 minute BurpeesDont cheat your burpees: they are chest to the ground in the down position and then a jump in the air as high as you can to finish the rep.  1 minute Air SquatsBring your ass to grass, and keep your weight on your heels!  1 minute Push UpsForm is key, so dont let those hips sag. If your form slips, drop to your knees instead of stopping. 1 minute Sit UpsDont hook your feet under anything- it takes the load off your abs. If you have trouble with your feet lifting off the ground or feel like your hip flexors are taking over, cross your legs to take them out of the equation. Repeat 4 times
