Hi,
I have been making very slow progress on ABR, and I just might have realized something about that.
Last week I did 4x36r and I made it, but it was really hard in the end and just barely made. I have been stuck in the 40s range for many months, dropped a bit due to recent time of because of back pain.
This morning I just did 5x36r, almost effortlessly.
I realize that I have been tensing myself and holding maximal tension every time I have been doing this, from the very first rep. Today, for some reason I decided to try to just hold enough force to keep the form good, and that made a huge difference. It was so much easier and I did not fatigue through the sets and I never even reached the burning feeling, although I had just increased to five sets.
Thinking about it, it makes sense. By exerting maximal force from the very first repetition, the muscles are going to wear out soon enough, regardless of how strong I get. Hence the plateauing, and never getting past a certain repetition range, in this case.
