When going downhill on a mountain bike in the "attack position", after a while I get one-sided lower-back pain that forces me to stop. How can I determine if this is due to an incorrect position or just weak back muscles, without anyone experienced to guide me?
There is no doubt that my back is not strong enough.
The pain comes sooner if I stitch my butt out more, however, my understanding was that that is exactly the correct position.
The pain is on the opposite side to my forward foot. Is it perhaps better to train myself to use either feet forward instead of preferring one?
