“I am determined, have more energy, and have fun becoming physically and mentally healthier. My knee is still arthritic and my vertebrae still ‘slip,’ but we do exercises that strengthen rather than aggravate them. It is a challenging work-out, but the payoff is priceless. Since Lis has created a flexible and dynamic workout for me, I am never bored and always feel stronger and happy. Fist bumps all around!”
