You can improve only what you put in. This isn't a genetic thing it's a work thing. Work out seriously with core like I've been doing for a year and you'll know you did it right.

Where did you feel it? That should tell you. If you just lost it because you burned out (felt burning) that should tell you. The shaking is probably because of a lack of stored body juices, that's a technical term, so maybe try something other than carrots and celery in your rabbit diet.

Otherwise you will get better with core training.
