I have a few of Cathe's weight videos (PUB, PLB, ME, PP, and SS) and am planning to order more (MM, GS series, and S&H). I've managed to do my workouts w/out a barbell but some of the back exercises I wonder if I'm getting the same results as I would if I were using a barbell. And, these new worouts that I want, I noticed the barbell is used more often. How many of you too use only dumbells for her workouts and is it necessary to get a barbell. I actually want a barbell but we live in an apartment and I already have more equipment than my husband would like. Maybe I can somehow convince him.
