A glute-ham developer trains the posterior chain - hamstrings, glutes, low back - through a range a normal back extension can't reach. It's the piece most home gyms skip, and most backs eventually pay for skipping it.
Commercial-grade Body-Solid, built to outlast the room, ships free.
Start here: the Powerline Roman Chair (PCH24X, $225) covers hyperextensions and reverse hypers for most lifters. Training glute-ham raises seriously, the Pro Clubline Glute Ham Machine (SGH500B, $755) is the real deal - commercial-grade and built for it.
