What is the difference?

Correct form. Some machines don't fit a woman's frame. I used a exterior oblique machine to strengthen my core. It will build muscle to make your mid section thick (straight up and down waist) Not an hourglass shape. Who knew...lol

Oh okay. That is nice your gym has a class like that. I read this article a long time ago https://www.t-nation.com/training/sexy-female-training and talked to some trainers. It talks about how Britney screwed up her midsection overtraining her abs. It is an interesting read if not entirely accurate.
