FitYaf's 30-20-10 Fitness Friday Workout

This weekend, I'll be saying goodbye to the year 30!  It has been a great year for me both professionally and personally, but I have a feeling 31 is going to be just as great!  I put together this workout to share with you as a tribute to my 30th year.  Give it a try and let me know what you think.

Notes about this workout:

• Some of the moves in this workout are high-impact.  Please feel free to modify the workout to make them low-impact if necessary.
• If you're unsure about any of the movements, check out the videos linked to the name of the exercise or google them before you start the workout.  You don't want to lose momentum, stopping after every exercise to look up how to do them.
• This workout is designed as a circuit.  Do each exercise in completion (30, 20 or 10), before moving on to the next.  When you finish the circuit, go back and do it again, so that you do each circuit for 4 (beginner), 5 (intermediate) or 6 (advanced) minutes.
• Rest in between circuits if needed, but no more than 1 minute!
