Hi Cathe - I have been using your step tapes for a year and MIS for six months. I had been doing Body Pump for a year and half before that and I still noticed definite results with MIS - I really love it. I'm considering having surgery that would require me to take two weeks off from any workout, and one month of no upper body work. I'm wondering how much strength and definition I would lose in that amount of time and how long it would take me to get back to the level I'm at now. If Cathe can't answer I would appreciate advice from anyone. Thanks!
