Floor protection mats for your home gym. If you enjoy working out at home, puzzle mats are the perfect addition to your fitness equipment. The foam mats can be assembled in any configuration and expanded as needed. This way, exercise equipment like a cross trainer fits easily on the gym floor. The workout mat also protects the floor from scratches and dents. At the same time, your neighbors will thank you, as the exercise mats absorb shocks and reduce loud noises during your workout.
