BETHESDA, MD (NIH) - Older people who hibernate during these chilly months could lose stamina, strength, and flexibility. Stay fit while you stay warm this winter with the National Institute on Aging's inexpensive, at-home exercise program. "Exercise with the National Institute on Aging", the 48-minute video, is based on medical research and "road-tested" by scores of older Americans.

The exercise program emphasizes:

--ENDURANCE EXERCISES, which increase stamina and may help delay or prevent diabetes, colon cancer, heart disease, and stroke;

--STRENGTH EXERCISES, which increase metabolism helping to control weight and regulate blood sugar. Studies show, they also may help prevent osteoporosis;

--FLEXIBILITY EXERCISES, which may help prevent and aid recovery from injuries; and

--BALANCE EXERCISES, which help prevent falls -- a major cause of broken hips and other injuries that lead to disability and loss of independence.

As added motivation, participants who stick with the program for a month will receive a certificate of recognition signed by NIA Director Richard J. Hodes, M.D.
