Coaches fill it with a small amount of water (up to about 3 lb), then secure it so the tube sits where the limb narrows — such as just below the elbow on the forearm. The water never fully settles, so every movement produces real-time feedback about path quality.\u003c\/p\u003e\n\u003cp\u003eCompared to larger water implements that sit in the hands or across the shoulders, the Waterboy Junior moves the shifting load directly onto the limb, so the athlete feels instability exactly where the glove, mitt, or arm-swing path lives.
