Interested in feedback from anyone with experience here. Abs (anterior and medial core groups, I suppose - but not lower back areas) are currently my weak link, both in terms of strength and hypertrophy. I need to bring these up for general strength purposes and hypertrophy here wouldn't suck either. I'm not particularly invested in the Steve Reeves/Frank Zane silhouette, so gaining some muscle here is not something I object to. I've heard some good things about ab-wheel rollouts (fit-ball to start with perhaps), decline crunches and bent-leg raises with lumbar flexion at the apex. Anyone have some good experiences/recommendations to share?
