Buying Guide: Century BOB Freestanding Punchbag


Whether you’re an experienced martial artist or just getting started, chances are there will come a time when you need to invest in the most important of training equipment: a punching bag.

For one, you really can’t just run out and start hitting things-- or people. So, you’ll need a bag... and not just any bag.

One of our top-rated products, The Century Bob Free Standing Punch Bag may strike fear into the hearts of your children, but it could also be the best sparring partner you’ll ever have. There’s no denying that good ol’ BOB is one heck of an investment, so we’ve given you the low-down on everything you need to know before bringing this lovable lug home with you.

Century BOB Torso Training Bag Vs. Heavy Bag

One of the most common questions customers have before purchasing is how this punch bag differs from the Century BOB alternative: a traditional heavy bag. While the human-like “skin” and gnarly snarl are obvious, Bobby boy has many other characteristics that separate him from the pack. Here is our comparison of the two:


One of the commonly discussed cons about a Century BOB body opponent bag is that there is less resistance than a heavy bag. However, it definitely depends what weight you’re used to training on. Our opinion is that it feels a bit like a cross between hitting a 30-40 pound bag and hitting mitts. The Bob offers a resistance between the two but you can punch through it. When digging into the body, BOB holds his base pretty well. Almost as if you’re hitting a solid body with a small amount of give.


One thing BOB has going for him is mobility. An empty Century BOB weighs about 22 kg and around 122 when filled with water or sand. Meaning that, unlike a heavy bag that is fixed to the ceiling, you can move the BOB where you’d like when empty.


The advantages of striking a human-shaped target are fairly obvious if you ever plan to compete. The realistic body form allows you to target areas as you would on a opponent. This kind of realistic targeting (not to mention mere satisfaction of striking a human form) simply cannot be gained from mitts or heavy bag work. The lifelike characteristics of the Century BOB will allow you to practice liver shots, uppercuts and solar plexus in a more realistic manner.

Additionally, unlike most human opponents, BOB is highly customizable. You can easily adjust the height in order to practice specific techniques depending upon the height of your opponent. 

You can also remove the torso altogether and use Century BOB without his base as a grappling dummy. Use him to practice your ground pound and throws to your heart's content.

However, one of the drawbacks is that it doesn’t swing back at you the same way a heavy bag does. As the Century BOB (or any freestanding punch bag) is not suspended in the air, it will not swing towards you in the same way a heavy bag does.


The BOB is constructed of high-strength plastisol, meaning that it is just as long-lasting, if not more so, than a heavy bag.

The material used to construct BOB is soft, meaning that it doesn’t hurt your foot or hands when throwing kicks, and you shouldn’t have to wear shin guards or other protective gear.

Which Kind of Century BOB Punch Bag is Right for You?

There are a few different BOB models that vary in size and price. Which one you choose ultimately depends upon your size, available space, and fighting style/training requirements. All of that is to say, don’t just go acquainting BOB size with your masculinity. Do some research beforehand to decide which Century BOB Freestanding Punch Bag is best for you.

Century BOB Freestanding Punch Bag (Classic Model)

The classic BOB model will run you about £300 full-price and includes the torso and freestanding base. Like the other models, it can be filled with water or sand. When fully filled it weighs in at about 122 kg (19 stone). This likely sounds like a lot, although the base does lift slightly when you deliver a powerful kick, so be careful of what you throw (or kick) at BOB.

The mannequin is smaller than the BOB XL at: 30" x 22" x 12" and features seven adjustable heights that range from 60” to 78.” The adjustable heights are awesome as it lets you practice delivering strikes to opponents of different heights.

Century BOB XL

The Century BOB XL is pretty much the same as the classic model in terms of build and quality. The life-like material used to construct the punch bags is consistent among all BOB models. However, as the name suggests, in terms of size the BOB XL is much larger than the classic model.

The body has been extended downwards, so BOB XL has a pair of upper uni-thighs. Which kind of makes him look like an angry merman, but is also great for throwing instep and groin kicks as there is more surface area to work with.

The only slight downside of BOB XL’s size is that the base is the same size as the classic model. Same base, but more BOB make him a bit on the unstable side if you throw really heavy punches/kicks.

So, if you’re looking for something that will let you try out a few extra techniques, the Century BOB XL is likely the way to go.

Century BOB Junior

Sometimes lovingly referred to as Century Bobby Bully, the Century BOB Junior is the kid’s version of the classic BOB model. Depending on your child’s chosen martial arts discipline.

BOB Junior is great for at-home training, or just a great way to spend some energy. Unlike most kids martial arts sparring partners, BOB won’t hit your child back.

The material is softer and gentler on hands than the adult version (or most other punch bags), making it perfect for teaching young children. Additionally, with anatomically proportionate features, BOB Junior is great for learning accuracy and proper technique, as well as practicing self-defence.

With two height adjustments (4ft2 to 4ft7), BOB will grow with your kiddo, so he’s sure to be a cherished addition to your home for years to come.

Bringing Home the BOB

To BOB or not to BOB is ultimately up to you. But, as discussed earlier, you’ll need some sort of bag sooner or later. If beating up a human-looking dummy is at all appealing to you, or if you want to improve precision and targeted attacks, investing in a Century BOB or Century BOB XL probably isn’t a bad idea. Additionally, unlike a traditional heavy bag that you have to hang from the ceiling, BOB can be moved fairly easily, and doesn’t require much by way of instillation.

If you value the convenience of a free standing bag, as well as life-like characteristics and enhanced training opportunities, then a Century BOB body opponent bag is likely the right choice for you.
