Heartline’s athletic training series is comprised of five product families--CoreRack™ Training Series, Auxiliary Training Series, Circuit Training Series, Free Weight Essentials and Accessories, and Cardiovascular Training Series.) Since Heartline is “systems-oriented,” our products are designed to serve more than one purpose. For instance, Heartline’s Dual CoreRack™ training systems allow two student/athletes to train in all core lifting disciplines simultaneously (benching, squatting, deadlifting, and power cleaning), or a total of four student/athletes per system with spotters. As a result, installing a series of Dual CoreRack™ training systems along a wall creates a substantially more effective, focused and safe training facility for the class instructor/strength coach.
