Alternative to hyperextension machine?

[Sassy69]

The gym I'm looking to join doesn't have a hyperextension machine. Its very annoying because I really enjoy using these things & its a nice stretch as well. However, they don't have one. Any suggestions for alteratives to using this? I've used it for hams & glutes. I've used it for abs, however I can replace it with a Step platform & sticking my feet under the free weight stand.
