The ideal flooring for a home gym depends on your workout preferences and budget. For heavy lifting or high-impact exercises, rubber flooring or interlocking foam mats provide excellent shock absorption and protection for your floors. If you're on a tight budget, an exercise mat can suffice for bodyweight exercises and yoga. Alternatively, you can use plywood or stall mats for a more cost-effective solution. Ultimately, choose flooring that suits your workout routine and provides adequate support and safety.
