You woke up this morning determined that today would be the day you'd take your workout to the next level—to try something completely new that you have never tried before. You mapped out your workout, carbed up, and filled your water bottle.

Wait a second; I thought today was the day you were changing your routine! If you want to shake it up and introduce something fresh, why not start with your warm-up?
