She worked out 2-3 times per week to start with. She only did the work outs I created for her. Today we've dropped the cardio from my routines as she walks on her own now for cardio. She is doing a pyramid routine for weight work 2x per week and loves it. She does her cardio on different days either 1 or 2x per week.
Her diet was awful. She usually ate once a day and it was some unhealthy dinner eaten late at night. That being said, it wasn't hard to improve on her diet.
I simply got her eating several times a day. I stressed eating 3 meals a day ATLEAST and especially breakfast which she NEVER ate and I encouraged healthier snacks, etc. Her diet is far from clean. I don't expect that from her. It's not her thing. She is eating Lean Cuisines for dinner lots of times to help with fat and portion control. She snacks on granolas bar often. I think she eats something small like a piece of fruit or a yogurt for breakfast. I'm not really sure what lunch is for her. She also liked to eat soup in the colder months. ANYTHING is better then the diet she left behind!
The original circuit I created for her was set up similarly to Cathe's bootcamp. I had her do 1 cardio, 1 upper, 1 lower and 1 ab exercise. Wash rinse and repeat for several rounds. I think her work out had 8 rounds in it. Being so out of shape, she took lots of breaks in between exercises. That was fine at the time. She no longer needs to do that now.
HTH!
