During the closed-chain strengthening portion, participants will execute the same six-strengthening exercises as stage I. The next phase involves progressing to a moderate resistance load that will allow the participant to complete 2 sets of 8 to 12 repetitions of a given exercise. When the participant is able to perform more than 12 repetitions with a given load, over the course of 2 successive training sessions, then the resistance will be incrementally increased. The maximum resistance will be against body weight (no support from bands).
