trying to fight the saggy skin myself with weight training. I take a 1 hour long class (2 times a week) at the local Y, its called 'bodypump' you work your whole body with weights as a class. I LOVE IT! I actually think I'm becoming addicted to it. I love how my body is transforming, and it seems like my 'saggy' skin is less. Now, on the other days of the week, I take Zumba for cardio...So yep, I will fight the saggy part of this process with all my might;)
