Interlocking Rubber Floor Mats (3/4 Inch)

Do not skip this. This is the single most important purchase after the shed itself. Heavy-duty rubber flooring protects your foundation from dropped weights, absorbs sound, and provides a stable, non-slip surface for lifts. It's the foundation of a safe and durable gym.
