Yeah, I recently had a bike fitting and they put me in a considerably more aggressive position - bars even lower beneath my seat than they were, and seat a few mm higher. After that my glutes started hurting, which I chalked up to beginning to use them more than I used to. Working on pedaling circles makes that more noticeable. Bridges might be a good idea....
