You’ve seen him on TV shows, in your favorite movies, in news clips and in the windows of your local dojo. That’s right – it’s BOB, the Body Opponent Bag!
BOB was the first-ever mannequin training bag for martial arts. So, what is it that makes a Body Opponent bag so special? BOB gives you a realistic human torso shape for a striking surface. Since you are training to fight against a human (presumably) this shape allows you to train with a higher level of accuracy than a regular heavy bag or punching bag.

Can you imagine always having a training partner readily available? Someone who won’t flinch away from the toughest punches and kicks? That’s what it’s like to have BOB in your home or gym!
Space isn’t an issue with BOB, either! The Body Opponent Bag is a freestanding bag, with a rounded base. To move BOB, you can easily tip the base onto its side and roll it into a storage space. Keep it in a corner, closet, or other out-of-the-way area until it is time to train. Then bring it out and get to work!

BOB is ideal for training in just about all standing martial arts! Any martial art that would use a regular punching bag, heavy bag, or heavy hanging bag, will work with BOB as well. Karate? Sure! Taekwondo? Of course! Tang soo do, muay thai, kung fu? You bet! And if you train a martial art with tactical applications, like krav maga or jeet kune do, then you’ll really notice the value of BOB. You can practice strikes that are not competition legal, like slaps, palm heel hooks, eye jabs, and more.
If you want an even bigger mannequin bag, make sure to look at the BOB XL freestanding bag!
