Always start gently, especially on areas that feel particularly tight or sensitive. Begin with light pressure by placing only a small amount of your body weight on the ball. You might want to first try it on the sole of your foot or a larger muscle group like your calf before moving to more delicate areas. The ball works by applying pressure to release tense soft tissue and trigger points, which can sometimes feel tender, but it should not cause sharp or shooting pain. Avoid rolling directly over joints, bones, or any area with irritated skin. If you feel a dull ache or a 'good pain' that releases after a few seconds, you're likely in the right spot. If the pressure feels too intense or the discomfort does not ease, immediately reduce the weight you're applying. Listen to your body; this tool is meant to aid in muscle release, not to force it. If pain persists, it's advisable to seek guidance from a qualified specialist to ensure you're using it correctly for your body.
