I'm considering buying the HIIT 40/20 download, but looking at the preview video I'm a bit worried about it being too high-impact for me. I do have a bad back (and downstairs neighbors!); normally I'm fine with Cathe's videos but things like jump-tucks just kill me. Do-able anyway? Also - my step only goes to 10 inches (it's the gray-and-black Reebok kind); will it work anyway? (I'm only 5'1", so I figure maybe I can get away with it; but I normally do all Cathe's step videos at 10" so am not sure if it will be intense enough and/or if it will require me to bend over too low.)
Any thoughts much appreciated! Thanks.
