I also teach a circuit class called BodyWise. It combines functional movement (cardio, resistance) and balance, which is a really effective way to get people moving.
I have every kind of person in my class: teenage girls, 60-year-old men, deeply conditioned people, etc. Even though the moves are rigorous, no one's going to hurt himself.
I make sure to take care of my body after training, too. My husband and I have a big barrel sauna and a cold tub that we use. It’s important to do that kind of therapy before you get hurt, not just to treat an injury.
We also just launched a new supplement line after many years of trying every product out there. We created what works best for us; a quality protein, a recovery formulation, a healthy energy, omega's, greens which are the best greens we have ever tasted, and a meal replacement drink for those on the go or wanting to lose weight. They are all available on our website.
When you train in a way that pushes you, but that also allows you to modify the movements so that you don’t hurt yourself, you do your body and mind a lot of good.
To me, training is a path to happiness and health. If you have issues in your life, you can get things right by starting with your body; things will make more sense for you when you move your body on a regular basis.
