After suffering a lot from back pain and cramps, which seem to be related to ABH and windmill, I have been thinking about the way I do these exercises. It seems to me that ABH is very different from HBH (FL/PE1), and not just because I bend the other way. When I do HBH I find the 'right' hollow position, using proprioception and cues to find the right bend, protraction, PPT etc. The position is reasonably comfortable, but then of course after some time this nice burning sensation in the abs sets in, so I cannot yet hold it 5x60s.
But in the ABH it seems that I am not finding a 'right' position, but always struggling to increase the ROM. This means that instead of holding a steady tension in my muscles, I am pushing at something close to maximum tension to increase ROM throughout. And this pushing with full force is very unpleasant to sustain for a longer period. I also think it carries a high risk of injury, and is responsible for my lumbar pains. Finally, it means that it is very hard to progress, because as I get stronger, I am just able to push further into the position and increase the tension - so I cannot hold it for more seconds.
But is this wrong? Is there a 'correct' balanced ROM that I can find and maintain without pushing agains the body's resistance, similar to the sensation of doing HBH?
Thanks,
M
PS: I have noticed that most people have difficulties with ABH, and thought this might be the reason. I think I have read most posts on the forum about ABH.
