Middle-aged and elderly individuals may be able to slow some of the effects of aging on the cardiovascular system using exercise. To get the desired results, people-with their doctor's approval-need to participate in strenuous exercise for at least a half-hour three times a week.
That conclusion is from an analysis of 37 studies including 720 adults aged 46 to 90. In those studies, people who participated in at least 30 minutes of exercise three times a week and achieved at least 80% of VO2 max-the maximum oxygen consumption, which is a measure of the ability to transport and use oxygen during exercise-can slow the decline in cardiovascular health that accompanies old age.
Individuals who exercised at this level for more than 15 weeks showed no significant benefits over those who exercised for less than 15 weeks, suggesting that improvements can be made in less than 4 months and then maintained after that point. The investigators found no difference in fitness between people who walked and jogged, and those who cycled.

Wouldn't it be nice to have a fountain of youth? Well we have one and I assure you it is truly magical, but not easy. A healthy eating plan and exercise are the foundations of warding off the degeneration that nearly everyone seems to experience in our culture as a result of less than optimal choices.
However, it is important to take adequate antioxidant support when exercising vigorously. This would be vitamin C 500-1000 mg , lipoic acid 100-300 mg, and 3-5,000 mg of glutamine (precursor of glutathione).
