In the 8 Keys of Strength article, Dave Tate mentioned that most people's hamstring strength was very poor, and as a result, the first time they started using a real Glute Ham machine, they would have to build up to it. Last night was the first time I was ever able to use a GHR, and I discovered that Dave was absolutely right, even to his predictions of how many reps most people can do.
Now here is my question: I have been doing the suggested exercises for hamstrings when you don't have access to a bench, and I am still very weak in this movement. Are the other hamsting exercises just not that valuable, or am I just struggling to adapt to the GHR bench? And yes, I have been doing the other exercises with good form.
