Moderate-intensity exercise, studies show, effectively lower blood pressure in people. New guidelines recommend 30 minutes of moderate-intensity physical activity (primarily aerobic exercises like walking, swimming, rowing, and bicycling on most, preferably all days of the week for people with mild to moderate hypertension. On the other hand, isometric exercise, for example weight lifting, should be avoided or limited to light weights.
Moderate exercise, such as walking, is a recommended part of the treatment for hypertension, but does it reduce the risk for hypertension?
Thirty minutes of walking three times a week may be enough to help lower blood pressure and start you on the path to better health.
A new study shows that even a little bit of weekly exercise is enough to lower blood pressure and improve overall fitness. The results showed that 30 minutes of walking three times a week -- even if it was broken into 10-minute walks throughout the day -- was enough to have a healthy effect on blood pressure as well as measurements around the waist and hip.
Researchers say these results may help motivate people to fit in even a little exercise here and there to benefit their health.
ACSM recommends at least 30 minutes of moderate physical activity five days per week for healthy adults. The guidelines also state that physical activity can be broken up into 10-minute bouts and be as effective as one longer session, a recommendation confirmed by another study on the effects of brisk walking on hypertension.

When we become "stressed out", our bodies react by releasing stress chemicals, such as epinephrine, nor-epinephrine and cortisol, into our blood. This is normal, and part of the "fight or flight" response that is innate within us. Walking can reduce stress by helping our bodies metabolize these stress chemicals. Exercise also causes our body to release endorphins, which are natural stress busters that also help relieve pain.

Cardio-respiratory fitness refers to the ability to be able to sustain rhythmic activity over a prolonged period of time. Aerobic activity such as walking, jogging, swimming or cycling can help improve your cardio-respiratory fitness level by strengthening large muscle groups within your body.

Exercise helps fight depression, as the endorphins that are released when you are active have a wonderful calming effect on the body. You may have heard this benefit referred to as "runner's high."
