Quick Anywhere/Anytime Workout

We've always got reasons not to workout - no equipment, no time, no space. Am I right? I've got a quick workout for you that takes away those excuses and you can take it anywhere.  Forget the mindset that you've got to be in a gym, have a ton of equipment, work out for hours...we're starting simple (but still challenging).

Start with a few dynamic stretches and warm-up movements such as arm circles, marching in place with high knees, cat/camel stretch, body weight squats, and leg swings.

Beginners should perform the following circuit 2-3 times with 1 minute rest between cycles, brief rest between exercises only as needed.

Intermediates should perform this circuit 3-4 times with 30-45 seconds rest between cycles, no rest between exercises.

Advanced exercisers should perform this circuit 5 times with between 0 and 30 seconds rest between cycles, no rest between exercises.

Circuit

20 jumping jacks
10 burpees (chest to floor)
20 jog w/ high knees (left + right = 1)
15 mountain climbers (left + right = 1)
15 fast paced squats
10 push-ups
15 sit-ups (arms crossed over chest)

All exercises can be modified to increase or decrease the intensity or to accommodate injuries.  This is a deceptively tough workout, so don't be discouraged if it kicks your butt or takes you longer to complete than you expect.  If one time through is all you can do - then that's where you start!  You'll build from there and that is perfectly F-I-N-E fine.  Try each time you perform this workout to do it a little faster, use fewer modifications, or add another cycle. 

Be sure to cool-down after you've completed your workout with some light movement (walking works!) and some stretching.
