Century Wavemaster XXL Training Bag Overview


Large hitting surface

A large hitting surface (52″×18″) helps boxing because it allows you to practice a wide range of punches, including the jab, cross, hook, uppercut, overhand, and straight. It also allows you to practice footwork and punching combinations.

The large surface is also beneficial for those who want to practice kicks as well. You can land high and low kicks and knee strikes as well. This way, XXL is a good choice for MMA, Muay Thai, and kickboxing training. (It’s a good Muay Thai bag alternative that doesn’t require installation.)

Such a large surface ensures you have enough space to develop your techniques no matter what sorts of martial arts you do.

Stable design

Theis standing bag has a large and low-profile base which we can fill with sand or water up to 270 pounds. That gives the bag excellent stability. There are only a few complaints about falling over made by professional athletes who can kick with enormous power.

If we place it on a smooth floor, it moves, particularly if we kick it. That’s not bad since we can practice footwork. But, if you find it annoying, place a rubber mat under it.

Used materials

The exterior is made of long-lasting vinyl, which is easy to clean. The stuffing of the standing bag is foam which absorbs the punches and kicks well. Some people find the filling a bit soft, though, and the problem is that we can’t add extra filling to the training bag to make it harder.

The base is made of strong plastic. Users don’t complain about water leaking.


  • Versatile equipment, suitable for any combat sports.
  • Large hitting surface.
  • Sturdy design.
  • Heavy-duty materials.
  • Color options.


  • We can’t modify the filling.
  • Moves on the smooth floors (use gym mat).
  • It’s better to fill the base with sand for maximum stability.



Century BOB XL Overview


Adjustable heights

We can adjust the high of the dummy from 60 to 82 inches. That’s a beneficial feature since we can set the bag to our height. Also, we can fix it for high and low kicks. We can also remove the “human-body” to use it as a grappling dummy. This way, we can use the BOB XL for almost every type of martial arts. Plus, it’s easier to move the equipment around.

Human body look

Punching a human-like object is gives a different workout experience than a standard heavy bag. We can practice how to land punches and kicks on various body parts, improving head and body shots. For example, with a classic heavy punching bag, it’s hard to practice uppercuts. But, we land a huge uppercut or hook on BOB’s chin.

In a nutshell, the mannequin helps to have more realistic training.

How well does it hold up?

Interestingly, BOB has the same weight as the Wavemaster XXL, but there fewer complaints on tilting. That is maybe because the training bag itself is lighter and shorter. Also, the base is quite extensive compared to the body, which annoys someone because it’s in the way.


  • Adjustable height, removable body.
  • Versatile, suitable for any combat sports.
  • Sturdy design.
  • Imitate the real opponent, great to practice body and headshots.
  • Comfortable and durable hitting surface.


  • The hole on the base is small, so hard to fill with sand.
  • A bit of water leaking.
  • It’s a bit complicated to adjust the standing bag.


What are the main differences?

The exterior and interior

Both standing bags are made of a durable exterior. But, the BOB XL comes with urethane foam filling, which gives a better absorption. Also, the foam filling of Wavemaster XXL less homogenous, and we can refill it. So, BOB is the winner here.

The hitting areas

Wavemaster XXL has a much larger hitting surface, and we don’t need to adjust the bag to our height or for kicks. The body opponent bag gives a real fight feeling and great to target different body parts, but an adjustment is required. BOB is excellent for those who want to improve their martial art techniques. Wavemaster is better for general training.


Both training bags are the most steady if they are filled with sand. For an average level and size trainer, both pieces of equipment will do. Professional athletes landing powerful high kicks will upset both.

Price and Warranty

Both bags have almost the same price tag, which is around $350. That price higher compared to hanging bags, but they required less space, mobile, and no installation. Also, these bags are made by Century, a company manufacturing boxing gear for many decades. They give a 1-year warranty for both bags.

Which one is better for you?

Wavemaster XXL with its huge hitting area a good choice for practicing kicks and punches. Its simple design makes it a better option for those who want to use it for conditional training.

The Century BOB XL bag is also a quality standing heavy bag that provides good durability and functionality. It may be better for those who want to improve their kicking and punching accuracy and targeting for any martial art because of the human-like body.

Hi there, I'm Imre. I started boxing when I was 15, but nowadays I hit my old, dirty heavy bag at home (you know, family, business, etc.) I love boxing so much, so I made this blog to help people get started with it (at home).
