Century BOB XL

The primary difference is the torso length. The XL version features an extended torso that reaches further down, providing a larger surface area specifically designed for practicing body shots and low kicks that the standard model cannot accommodate.

Yes, the base is rounded, which allows you to tilt the unit and roll it across the floor. While it will be heavy at 270 pounds when filled, this design makes it significantly easier to reposition than a traditional heavy bag.

Water is the most convenient option for filling and draining, but sand provides a higher density and greater stability, which is often preferred if you are a heavy hitter or practicing powerful kicks that might cause the unit to shift.

While the materials are durable, the BOB XL is designed for indoor use. Prolonged exposure to direct sunlight and extreme weather conditions can degrade the vinyl torso and the polyethylene base over time.

When filled to its maximum capacity of 270 pounds, the base provides excellent stability for most training sessions. However, extremely powerful strikes may still cause some movement or rocking, which is typical for any freestanding bag.

The height adjustment mechanism is secure, but you may notice slightly more flex in the torso when it is extended to its maximum height of 82 inches compared to its lowest setting. This is a natural result of the increased leverage at higher positions.
