Low Pain Zones (Rating: 2 - 4 / 10)
Outer Shoulder & Deltoid, Forearm (outer/top), Thighs (outer), and Calves. These zones have thick muscle cushion, fewer nerve endings, and relatively thick dermis. Perfect for first-timers.
Moderate Pain Zones (Rating: 5 - 6 / 10)
Upper Back, Biceps (inner), Wrists, and Ankles. Slightly more sensitive due to proximity to tendons and thinner subcutaneous fat.
High Pain Zones (Rating: 7 - 9 / 10)
Ribcage, Sternum, Spine, Knees, Elbow ditch, and Throat. These areas have dense sensory nerve clusters with bone directly beneath thin skin.
