Abstract: Apparatus, systems, and methods for executing a “tire flip” weight lifting exercise. The disclosed apparatus includes a chassis and a tire assembly that is lifted and flipped during the exercise. The tire assembly includes a support bar that extends through a tire. The tire assembly also includes bearing assemblies that engage arms of a torsion bar that is pivotable with respect to the chassis to provide for safe and controlled movement of the tire assembly during the lifting exercise. When the lift is completed, rollers engage the tire assembly so that the tire assembly can roll back to the starting position at least in part due to the force of gravity.
