PHOENIX, Arizona, August 20. JR Rosania, of JR HealthPlex, has University of California, San Diego incoming freshman Jaimie Bryan demonstrate an exercise that can be used to improve a swimmer's breaststroke strength.

Bryan uses a TRX strap to perform a suspended breaststroke kick. Note that she performs that exercise while stabilizing her upper body on an inverted Bosu ball. Rosania recommends performing 3 sets of 20 kicks for improved upper body, core, and kick strength.
