Document: I first used BOB when I was in FLETC. I absolutely love knocking this guy around. My kids love beating this guy up too! Great for a training tool as well. This product is so much better than a standard punching bag. Gives you the ability to work on punch/kick placement. Great product!
version of punching dummy, and purchased it. We just used it in our first class of 2011. It is Excellent! We set it up to a height approximating a six-foot man, and had the students "fight" it for a period of about one minute using all the moves we had taught them. It is very realistic as a target, and absorbent enough not to hurt their hands or feet. At the same time, the surface does not cause abrasions, so no gloves are required.
I am not sure if sand would hold the base still better but it does not interfere with the work out at all! It's a great work out! He takes punches really well. Anything you can do on a speed bag do it to his face. the anatomy makes your work out so much more valuable. I have never gotten in a fight with a straight sided punching bag, i think those are pretty useless. Bob offers many realistic targets and takes a beating really well!
Worked perfectly for what I was looking for. Sterdy and well made. I am very happy with this product. Thanks
This is the best punching bag. This should be the first and the last punching bag a person should have.
This is great, its big, its tough, and you actually get an adrenaline rush boxing it. Great for fitness!!!!!! Nice!
THANKS JUST RIGHTI use this every day for working out and it makes me fel more agile in my boxing
It does its job and more. Good quality Body Bag, quick shipping right to my door and its adjustable to your comfort. I would recommend it to any one especially for stress, every one needs to strike something once in a while.
I teach personal protection and have a number of these. The base needs to be smaller if possible but that is more a design flaw/necessity. The product works well and can take a beating.Seller delivered on time with no issues.
I run a non-profit, public-service firearms and personal security school that teaches about 60 percent women. We have been, among our other classes, teaching a class in unarmed self-defense for women and girls only for about four years. Two years ago, we bought the "Original" Wavemaster punching bag, and use it for teaching basic defensive blows. It is excellent for that, but we wanted something (other than the instructors) that the students could apply full-power defensive moves to.
Answer: no
