As we all know from working out in the gym, resistance training is the key to building strong muscles of any type. Much like performing bicep curls without weights - where your arms may get tired, but won’t get significantly stronger over time - performing pelvic muscle exercises without the added benefit of resistance training will not result in maximum pelvic muscle growth or strength. The Private Gym’s ergonomically designed, resistance equipment and magnetic weights, provides consistent, precise, and measurable resistance.
