Review on MaxxMMA Double End Heavy Bag Anchor - Unfilled Weight Bag for 🥊 Enhanced Core Training, Punching, Boxing, MMA, Workout, and Fitness - Multifunctional 3-in-1 Tool by Chris Hanson

We bought a total of 5 of these brackets to hold the corners of our heavy bag stand. It's a durable construction with a strong zip and a Velcro flap covering the zip. After closing, none of them leaked sand. They also have handy carry handles that make it easy to carry them to our practice room. Definitely recommended. It made more sense for us to use these soft, sand-filled bags instead of the cast-iron weights to avoid possible toe-banging on the weights. They are valued at around £30 each. We started with 3 and added 2 more to keep our 100lb bag from shifting after my wife punched and kicked like a professional kickboxer. He's not moving now.
