How to lose stomach/tone tum?

Jillian videos. She is hard core and has the best abs.

It's interesting that you're getting such varied responses. I think part of it has to do with using the term term "toned". To this day, I still don't know what that really means, since I first heard it being tossed around during the early days of Jane Fonda videos. LOL

Based on your photo, you look great in clothes, which brings to mind a different term, that of being "skinny fat". You may want to research it online. If that's what you're talking about (and I don't think you're talking about loose skin as a result of losing weight too fast), then there's a lot of information online about body recomposition, and not doing even a million crunches or some other variant, or planks for that matter, is going to accomplish that. Good luck!
