I am a 41-year-old mother of three (youngest will be 3 in May) and have been working out between pregnancies and young babies since 1987 (mostly doing Firm tapes before I discovered you 1 1/2 years ago). Since then, I've been alternating your strength (2-3x/wk, mostly MIS and now ME and PUB/PLB) and cardio videos (2-3x/wk, including the "Imaxes" 1x/wk) plus a 60 min. power yoga tape 1x/wk. I consider myself an advanced exerciser. For the past 4 weeks, I have been thoroughly enjoying your advanced overall bodyblast rotation with the Intensities. My problem is that I'm already quite thin (5'9", 125 lbs) and even though I eat quite a bit (ask my DH!), I'm getting thinner (but a bit more muscular - a good thing). On the other hand, my abs are still flabby and not very strong. If I hold them in (something I'm a pro at!), they look defined; if not, flab city! I've had to modify ab exercises all of my exercising life because they're so weak. (Pushups are another story - *sigh*) I would love to strengthen my abs and lose more fat there but NO PLACE ELSE! I know there's no such thing as spot-reducing, but since I'm already too thin every place else, how might I go about achieving this goal? Thanks in advance for any advice! You have brought me to a whole new level of fitness!
