To what extent can past athletic achievement be used to predict future performance? And what’s the best way to crunch the numbers? Mac Ward and Gillian Mounsey went looking for answers with a special workout. Gillian finished third in the 2008 CrossFit Games. Mac is a Marine who runs CrossFit Cherry Point.
Mac used a workout he called “Diafranabeth.” It combines the first round of Diane, the second round of Fran, and the third round of Elizabeth.
It looks like this:
21 Deadlifts at 185 pounds
21 Handstand push-ups
15 Thrusters at 80 pounds
9 Squat cleans at 105 pounds
9 Ring dips
Gillian averaged her fastest and slowest times on Diane, Fran and Elizabeth to come up with a predicted time of 6:25. Mac used a different formula, taking into account the differences in male and female weights, to come up with a predicted time of 5:37.
Then it was off to Mac’s garage for the workout. Mac jumped behind his camera to record the results for posterity. Turns out Gillian’s predictions were pretty good.
Editor’s Note: Always the provocateur, we asked Jocelyn Forest from CrossFit West Santa Cruz to try her hand at the workout also. Jocelyn won the 2009 CrossFit Games NorCal Regional Qualifier, and will be competing against Gillian at the Games on July 11th, 2009. Jocelyn’s Response video ... [wmv] [mov]
