For skiers getting in pre-season shape, James says doing functional movements is the key, and she’s showing Burks and Carr how it all works.

“When you think of boxing, you just think of arms,” Carr says, “but boxing stems from your lower body and footwork and core, exactly like skiing.”

First, James takes the two athletes through a boxing warm-up, teaching them technique and standard punches: jab, cross, hook, and upper cut. They shadow box, spar with James, learning how to “slip” or dodge punches, and then go right into Chance.

The circuit workout is 15 jumping pull-ups,10 box jumps, and five burpees. Not just one set, but 20, and the clincher is that you have to do all three exercises within 1 minute. The faster you do it, the more rest you have, but each set starts on the minute for 20 minutes. People pee their pants trying to do this workout.

“Let’s go!! Let’s go!!” yells James, still motivating the sweating, exhausted Burks and Carr. James says it can take numerous attempts to complete the workout, and when her athletes do it, they get to write their names on the “Chance” wall. Carr bested Burks (who, by the way, is in phenomenal shape for breaking her ankle last March) with 18 sets—James was impressed.
