ONE BALL, TWO THERAPIES These Massage Roller Balls can be used to provide either hot or cold relief as needed. Freeze a ball one day, and heat it the next. However, while you can use the balls for both hot and cold massage, you may want to buy a set of two, so you can alternate heat and cold in the same massage therapy session. Alternating hot and cold therapies with a muscle roller ball can be a great way to convert tight knots into relaxed muscles

APPLY TARGETTED COLD RELIEF FAST - Store the cold steel ice ball in the freezer for cold therapy on injured muscles. The proprietary temperature stabilizing relief gel inside the ice roller ball stays cold for over an hour. Cold therapy is perfect for trigger point therapy, myofascial release, and deep tissue massage. A chilled massager ball helps decrease inflammation and promote healing of strained muscles and sports injuries, as well as relieve pain from plantar fasciitis

REDUCE STRESS AND ANXIETY, PROMOTE RELAXATION, IMPROVE MOBILITY, SPEED RECOVERY, EASE PAIN AND MUSCLE TENSION with heat therapy. Use like massage stones for the health benefits of a hot stone massage. Warm the ball in hot tap water for 10 minutes, dry, and begin feeling your muscles relax when you apply the soothing warmth. Heat increases circulation helping to relieve cramps + muscle spasms in all areas of the body, but is especially effective for thigh, leg, foot, ankle, back, + neck pain

REMOVABLE SURE GRIP HANDLE The ergonomically designed handle of the therapy ball keeps the cold or hot surface of the ball away from the hand of the trainer doing the massage, and safe to be placed in the freezer or hot water with the ball. It can also be easily removed to become a foot massager, as you roll the balls around with the arch of your feet, giving yourself a thoroughly enjoyable foot massage without special accessories

ENJOY YEARS OF RELIEF WITHOUT WORRY Your balls can be frozen and heated over and over again, as the gel within should last for thousands of uses, way beyond the lifespan of other balls. Like all Cestari products, they come with a lifetime no questions asked warranty so you can relax knowing that these are the last massage balls you will ever need to buy.
