Each Roll Model massage therapy ball included in the PRO 6 Pack offers endless opportunities for healing and pain relief. The original Yoga Tune Up therapy balls are designed to help you effectively access trigger points and high-tension areas to ease various aches and pains in your body. Small and convenient, you can use them at home or on the go. In the PRO 6 Pack you will also find our Therapy Ball PLUS self-massage balls. These are slightly larger than the original YTU massage therapy balls, so they cover more surface area and add height to allow for a greater depth of pressure. They penetrate through dense layers of skin and muscle to improve ailments such as sciatica & back pain, IT band syndrome and more. Lastly, the PRO 6 Pack includes the sizeable ALPHA ball. Larger in diameter than the other two, this Roll Model massage therapy ball is designed to help you target your body’s larger areas like your hips, pecs, and buttocks. From migraines to plantar fasciitis, help your clients live better in their bodies with the PRO 6 Pack from Tune Up Fitness.
