I strained a muscle somewhere in my hip/lower back recently, and it's been a slow recovery. As it's gotten close to normal I've discovered that some of my bikes aggravate the injured area more than others. After careful measurement, I narrowed it down to saddle height. While I had intended to have all the bikes setup the same, it turned out there was some variation (about 1/2 inch) in the saddle height. The bike with the lowest saddle height caused the least strain on my hip/back.

Soooo..... Once things are back to normal, how should I interpret this?

A) The lower saddle height is best because it was most comfortable during recovery.

or

B) The higher saddle heigh is best because it is engaging more muscle groups.

FWIW, I'm not 100% certain but I think the injury came about from overdoing it on the leg press in the gym rather than by anything on the bike.
