Some say it'll make your leg muscle huge. Well not really, it will tone your leg muscles. Each teacher has their own focus. Like the class I attend on M W and F's focuses on stamina. All through out the workout, she keeps the pace very fast. I feel my heart pumping very fast. And the class I attend on T and TH's focuses on hard resistance. So a lot of the cycles for this class focuses on strength and agility.
With this routine I have been following for the past 2 months, I noticed that I sleep better at night and can carry a 30 pound toddler for a much longer time -- even up the stairs! I feel much better and have more confidence. Although I have only lost around 6 lbs, I can comfortably fit into a size 6 and can squeeze into some size 4 clothes.
Now dieting is a much different discussion.
