I've seen the results in myself and in others. Older women especially are now more aware of the benefits of exercise, but sometimes it's a tough sell. People would like to find an anti-aging pill they could take instead of having to make the commitment to exercise and sticking with it. I understand that. Exercise takes time, energy and work.
Seniors are afraid they're going to get hurt.
And they're intimidated by gyms filled with twentysomethings. People want to exercise, but they want to do it with peers. I'm their age or just slightly younger, so immediately they feel more comfortable. I have more credibility with them than a younger instructor. You have to be aware that older bodies need to build strength slowly.
