average_al, I’ll chime in here. I do have experience with the Rogers Pendulum Reverse Glute Ham, as well as the Nautilus Duo Hip, Nautilus 2ST Hip Extension, and the Hammer Strength Hip and Back/Glute. The Pendulum is a great machine. I like the strength curve and you can enter and exit the machine in mid-range, making it easier to get in and out. I have always preferred the fused bilateral movement arm over the Duo Hip’s independent arms. But, as in the videos, you can still use it one leg at a time if you wish. You can target the glutes by keeping the legs bent throughout the reps, or keep the legs straight the entire time and put the emphasis on the hamstrings, or do the reps in a leg press motion and work both.
The Nautilus 2ST Hip Extension is also a great machine. It has a 400lb weight stack and a release mechanism to allow easy entry and exit. It was also a fused movement arm unit. And has a much more compact footprint than the Duo-Hip.
Some on here will probably disagree, but the Hammer Strength Hip and Glute is a good machine. It has the smallest, most compact footprint of all. It is a very functional piece to have. Good strength curve, not great, but it works the glutes, hams, and lower back very effectively. The only thing I have an issue with is, you can’t get the waist belt tight enough if you’re training alone. You really need a partner to pull on the belt to get it tight enough to hold your hips down on the pad when doing it. But, i have also found that to be the case with the Rogers and the 2ST when I used those. Maybe to a little lesser degree. Have had the Hammer in our high school weight room for a long time.
The Duo-Hip is good. But personally, I prefer the other 3 I mentioned over it. I also think any of the 3 would work well using the 30-10-30 protocol. Don’t think the Duo-Hip lends itself to that.
And, the Rogers Pendulum machines are great IMO. I have 4 of them in my basement.
