The Biggest, Baddest Punching Bag! 350 lbs!
Brand new Super Heavy Punching Bag. Inspired by the bag used by Bruce Lee to develop his incredible kicking power! Made in the USA by Biltuff. A full 35″ in diameter and 5 foot tall! This monster bag weighs an unbelievable 350 lbs! Constructed of heavy-duty 22oz nylon impregnated vinyl , triple-stitched along all stress seams. Industrial web straps run the entire length of the bag for full support. Eight hanging straps (instead of the normal four!)

me hitting my 500 lb punching bag i bought at I&I sports in carson california for 550 bucks haha it was inspired by the big punching bag bruce lee used to practice his side kicks on nothing like the original but the idea came from bruce lee’s big 300 lb bag. they said my bag weighed 350 lbs but i think they lied because 6 people could not carry this thing we had to use a fork lift haha. i am not a fighter nor do i train to be a fighter i just do this for fun so know that before you type down negative comments. this is my first video i do plan to upload more thank you very much for your time and may you have a great day.

PLEASE READ! – This video demo is NOT a skill training session. The video shows two specific drills described in the article below:
http://www.rossboxing.com/thegym/thegym24.htm
Both drills are conditioning and power based, and also intended to teach the athlete to fight through fatigue. Skill should never be intentionally abandoned, but during periods of extreme fatigue, the athlete must be prepared to continue fighting despite skill deprivation (which can occur when all three energy systems are drained). By training to fight through extreme levels of fatigue, you will be more prepared (physically and mentally) to deal with such feelings during live situations.
Once again, this is NOT a skill based video and should not be confused with one.
