Hi. How is momentum different from original flex, did they just mix flex and core? I'm confused. Joined online. It'scheaper, private, and I'm blind and have transportation issues. I take meds for bipolar disorder, and, they pack on weight. I don't even know if I can lose weight while on these meds, but, if I eat sensibly, and continue exercising, at least I won't gain any more weight. I admit, the meds were an excuse to indulge in unhealthy food, since, I figured the deck was all ready stacked against me. I've had a change of heart, though. I want to be as healthy as possible. Take care.
Amie
