Bought about 25 of your videos because heard you would offer me a challenge. Have wasted tons of money on videos that hardly make me break a sweat! So far I've done about three of your videos which I found to be so so, (I found the exercises to be so common, i.e., b.o. rows, bicep curls, stomach crunches, lateral raises, presses...). I find that there is no creativity in those moves and I'm looking for creative exercises that let me work several muscles at one time, i.e. a shoulder exercise that incorporates a lateral left, press and a very slow eccentric contraction connecting both moves (per tamilee webb in her 'building tighter assets' video) or a lateral raise and hammer curl at the same time, i.e., the firm. Last night I did "slow & heavy" legs & shoulders for the first time. Awesome workout. I have about 15 others to do, so i'm hoping i find more creativity and challenge in those. I did do one of your videos where you did a lot with the ball, i.e., foot on ball while doing curls, leg lifts on the ball.... That was great. That is what I'd like to see more of. Creativity that CHALLENGES! Anything else is a waste of money. Reebok Step Challenge is another video that kicks my behind - as simple as the choreography is, it is hard!! I look forward to doing the rest of your videos but if anyone can offer me some short cuts as to what of Cathe's will offer me what I'm looking for, I'd love to hear it.
