I feel 85% better when I'm working out on a daily basis.
It really does make a major difference.
What I have found with the resistance training is that I tend to put on muscle very quickly. I know it has to do with my hormonal fluctuations, but I'm much happier toned and a little heavier.
Ironically, since I've become a fitness junkie my body shape has totally changed. I was busty and carrying a lot of weight around my waist. Now I have a toned body and a tiny waist. I kind of like the hourglass figure.
