US Patent 9211465 Sport training bag attachment

A training bag attachment on a heavy boxing bag for training boxing techniques, specifically an upper cut that requires an elevated preferably suspended target. The upper cut training bag attachment provides for multiple independent target punching bags spaced around the heavy bag. The target punching bags are vertically adjustable and spaced to be outstanding from the mounting bag surface for use. An elastic retainer assembly provides for automatic resilient return displacement after impact, affording a user multiple continuously resetting targets.
