This is an awesome website...I am in the market for a new workout. There are sooo many to choose from and a I need help from some experts out there. I am 38 years old and am a moderate exerciser. I work out at home to Power 90, a treadmill, free weights & machine. I am getting bored and need a great OVERALL body workout. I tend to focus on my legs and butt a lot as I feel that is my flabbiest areas. I would like your opinion on the best lower body workout and then an OVERALL great body workout as I need work on my arms and shoulders. I don't need to lose weight but really want to tone up and gain some muscle. Any input would be appreciated!
