Head Weight Harness. Use with 'weight discs' to strengthen neck muscles.
Well made and easily adjusted this harness works a treat. Wanna have formidable clinch defense, awesome traps and upper back muscles to boot? Just buy one.. Don't get me wrong I don't think that there's anyone who won't look a little silly wearing it but needs must. Simply put, I'd much rather go into a match up knowing I've done all I can to improve my ability to take a decent hit and not get sparked out.
