Review of BOB - Body Opponent Bag for Martial Artists

The Body Opponent Bag (BOB) is a fun and useful training tool for martial artists… as you get to train against (or is that beat up?) poor old BOB. Most Body Opponent Bag (BOB) models have adjustable heights (check the model specs). When the base is filled with water or sand, this heavy bag can weigh as much as 250+ lbs.

Our Rating – 4 1/2 STARS


  • Can practice accurate targeting by focusing on different parts of BOB's body (i.e. nose - palm strike, ribs - knee strike, head - axe kick, etc.)
  • Ability to practice self-defense techniques (i.e. eye strike) that might injure a "live" training partner
  • Easy to set up - when base is empty
  • Less need for boxing or MMA gloves due to BOB's softer exterior (versus the hard vinyl used in a Wavemaster Heavy Bag)
  • Adjustable height
  • Easy to assemble
  • Very useful if you do not have a strong ceiling and need a stationary ground-based heavy bag


  • Some users complain that Bob's neck can break after heavy usage
  • Can move around when hit (if the base is filled with water versus sand)
  • Very heavy (when base is filled) if you need to move BOB to a different spot
  • Can't practice low kicks (i.e. against an opponent's knees) as BOB lacks legs
