Core Max 2.0 Total Body Training Gym in Teal/Grey is used but well-kept, with only minor scuffs to attest to its use. Core Max 2. 0 was developed to accommodate 8 muscle-burning exercises accomplished over 8 minutes a day. It has a power-assisted (coil spring) rebound system that provides resistance and support in both directions, maximizing effects and minimizing strain. It has 4 click-stop settings of which 3 are resistance levels, the fourth, a storage mode. The Core Max is intended to burn calories and firm-up while in a seated and/or reclining position. It retails new on-line for about $80, a bargain here for slightly used, and available for local pick-up in San Rafael, cash, Venmo, or PayPal.
