it is great, and the two classes I go to are with two different instructors, who do things differently so it mixs it up.
by the way.. do crunches even count as strength training?
As for the class, I do enjoy it.. the music is blasting and the instructors walk around and make sure our form is good, and that we are doing it right. they are great motivation. ALot of the ladies do the exercises with 8 and 10 pound weights, and I'm going to try to move up to using fives the entire time next class. What should I aspire to down the line, what do you guys lift generally?
