The 3 piece Massage Lacrosse Ball Set from 4KOR Fitness was thoughtfully designed and provides 3 different styles of massage balls in order to release tight muscles on any part of your body. The double lacrosse ball, also known as the peanut lacrosse ball, is the perfect replacement for the homemade tennis balls-taped-together tool that so many people use for self massage. The peanut lacrosse ball is easier to use for many things than individual balls since it doesn’t squirm around and is designed to stay where you want it to without rolling away. The peanut lacrosse ball straddles your spine so you can roll it right down the center of your spine and loosen the erector spinae muscles that easily tend to tighten up. The single lacrosse ball is great to use on hard to reach muscles where the peanut lacrosse ball would not work effectively. We designed our spiky massage ball to have enough give that it won’t be too hard and painful to use effectively. The 3 piece Massage Lacrosse Ball Set also comes with the signature 4KOR Fitness customer service guarantee. If you need us, we’ll be there with a quick and friendly response every time. Whether it’s offering a refund or fitness tips, we’ll do anything we can to ensure your satisfaction.
