Weighting Reverse Hypers?

Has anyone had any luck weighting reverse hyperextensions? I don’t have access to a back extension, glute ham or reverse hyper machine however I lie across an elevated bench. The problem I have is holding a dumbell with my feet. It keeps slipping out and landing on the floor. I’ve also tried bands wrapped around my feet hooked under the bench with little success. Any thoughts? Thanks.

Try ankle weights?
Use a mini band?
