If I eat something a little crazy or if I feel sluggish, I know I have to eat better the next day and work out. I work out, I do circuit training so I try to keep my heart rate up whether I'm doing cardio, lifting weights or jumping rope. I like to mix it up. I also take Zumba classes - I love those, those are a blast.

All the circuit training, it's cardio circuit training, so everything you're doing, you're still running up your heart rate. You're burning, I think, triple the amount of calories than if you were just weight lifting.

We do a lot of lifting, and mix it up with upper body and lower body. A lot of circuit training for cardio. I hate just doing long distance running, so I do 5 or 6 different exercises for 20 to 30 seconds then move to the next one.

We live in the countryside, 15 minutes from the closest town, so I would never have time to drive and go somewhere. So I have a personal trainer come to my house, normally three times a week, and we do circuit training depending on what I need.

I'd been doing circuit training and Pilates for years, but I was not consistent with food. I'm not a disciplined person. I was indulging all the time.
