Some things we (instructors) want students to remember: Work hard. One way to do this without jumping is to keep your arms strong all the time. Make your arm movements deliberate and big: use full range of motion and listen to the cues given about what and when. 
Especially on song 4 and 9, push yourse…lf beyond your comfort level.

Think about why you are taking the class and remind yourself that change won’t happen unless you go farther than you normally do. You can always come down to a lower impact when you have to, but you could hit your AT during these tracks if that is where you want to go. Don’t be afraid of a little change. This class is designed to let you do great work.
