It is recommended that you buy a storage rack for your dumbbells. Not only will it help to protect your floors and keep your workout space organized, but it will also ensure that all your exercise equipment is securely in one place. Storing your dumbbells on the floor can shorten their lifespan depending on their material, ultimately costing you more money and time in the long term. Consider purchasing a dumbbell or a set of dumbbells with an included storage rack. They may be more expensive, but they’ll also help keep your exercise area neat and stress-free so you can fully focus on your workouts.
