Vigorous training and daily exercise can reap positive effects, but can often times lead to cramped muscles, soreness, and minor strains over time. These massage balls are portable firm balls that help target painful muscles and tissues on your body and help alleviate pain. Whether you are in the gym or on the go, the massage balls incorporate Trigger Point Therapy for your sore and painful muscles associated from training and sports. Roll out tight hard-to-reach muscles and deep tissues on back, feet, neck, legs and shoulders. The rolling action when pressed against your body helps increase circulation to problematic areas, while improving mobility and muscle tension. Best of all, the set of three massage balls are small enough, and can fit anywhere with the included convenient carry bag; suitable for short trips to the gym or long trips alike.
