Barbell Landmine Attachment for 30mm Barbells

This is an attachment for 30mm barbells, allowing you to perform landmine exercises. 

Simply slide it on, place the barbell with the attachment in a corner (in a power rack or against a wall) for optimal stability, and start training.
You can find suitable workout routines online. 

Please note that this attachment only fits 30mm barbells, not Olympic barbells with a 50mm diameter. It might be possible to scale this model, but I don't have a 50mm barbell to verify this.
