ResultSport Spiky Massage Ball 10cm

3 sizes target each muscle group - The ResultSport set contains three solid plastic spike balls measuring 6 cm, 8 cm and 10 cm so users with plantar fasciitis, tight calves, sore hips or stiff backs can match the ball to the muscle being worked. The 6 cm fits the arch of the foot, the 8 cm reaches glute and calf trigger points, and the 10 cm covers the wider back and shoulder area. Firm texture for deep-tissue fascia work - Each ball is machine-formed from a single piece of PAH-free and phthalate-free plastic with no glue in the construction, so the spike texture holds its shape under repeated full body weight. The textured surface presses through superficial muscle into the fascia layer that a smooth tennis ball or foam roller does not reach. Built for runners, office workers and pilates users - Office workers can place the 8 cm ball between the lower back and a chair to ease desk-bound posture tension during the working day, runners can roll the 6 cm under the arch after long-distance training, and pilates practitioners can use all three sizes for foot mobilisation, posture release against a wall and grip exercises in the hand. Light weight travel-sized mobility kit - The full three-ball set are light weighs and packs into a gym bag, handbag, suitcase or office drawer, so daily fascia work continues during travel, between physiotherapy appointments and during long shifts at a desk.
