"Spiro100 has the most comprehensive videos of exercise for those of us 55 and over. No matter what your physical condition, they have choices of chair yoga, tai chi, aerobic, heart and mental health. As you progress, you can go to standing with support, then standing without support for all of the types of exercise. So much variety and giving wonderful customer service, too. Thank you Spiro100 for getting me excited about improving my health."
