CrossFit catches on
Candy Robinson, Becky Messelheiser and Carol Ann Stentz join Sandy Neubauer, CrossFit level-one certified trainer, for their morning workout of 33 repetitions of the day's six exercises. A mat, weight bar, kettle ball and a medicine ball are all that's needed for today's CrossFit workout. Depending on a person's physical ability the amount of weight lifted can change to meet the individual's needs. (U.S. Air Force photo/ Airman 1st Class C.J. Hatch.)
