Soldiers perform 5 to 10 repetitions of each exercise in CL 1 with or without assistance, using only their body weight as resistance. The goal is to perform 5 to 10 repetitions of all five exercises unassisted. If a second set is performed, the entire drill is repeated in the order listed. Table 9-7 lists the body segments trained in CL1.
