I love this woman and I use her videos 6 days per week. I do find I need to mute the TV and use my own music (my computer is hooked up to my TV), but I find her moves very effective so I don't mind. I have a set of videos I go to daily for my abs one day, legs another day and arms/back and I rotate them and take a day off.
I've only been using her videos consistently since January. I was at my goal size, but her workouts has really helped me to tighten my trouble areas (triceps, lower abs, back).
Thanks for mentioning her website. I think I should drop her a note to say thank you.
