Century Martial Arts BOB Body Opponent Bag

The primary difference is the torso length. The XL version features an extended torso, which provides a larger surface area for practicing body shots and low-to-mid-range kicks that the standard model cannot accommodate.

While water is the most common and convenient option, filling the base with sand will provide significantly more weight and stability, reducing movement during high-intensity strikes.

Yes, it is designed for high-volume use. The high-strength plastisol skin and urethane foam core are engineered to withstand repeated, powerful impacts without losing their shape or structural integrity.

The BOB XL is designed as a freestanding unit for standing strikes. While it is durable, it is not intended to be laid on its side or used for ground-and-pound drills, as this can damage the base connection.

Adjusting the height is straightforward. You simply loosen the locking mechanism on the neck, slide the torso to your desired height setting between 60 and 82 inches, and re-tighten it securely.

We strongly recommend wearing boxing gloves or MMA gloves. The plastisol skin is durable, but hitting it with bare knuckles can cause skin abrasions and unnecessary impact stress on your joints.
