Wellness tips

Heart-friendly or aerobic exercises are walking, jogging, wagging, swimming, dancing cycling, skiing, rowing, and walking on treadmill. Such exercises are more efficient and give oxygen-rich blood to the muscles.

Heart unfriendly or anaerobic exercises are weightlifting and isometric contractions like pushup. Such exercises build muscles and do not require oxygen.


Follow the three simple phases of exercise, which are warmup, exercise, and cool down phases. These are, warm up for five to 10 minutes before beginning the exercises, tehn begin the exercises with gentle stretching of the muscles to be followed by rigorous exercises for about 20 to 30 minutes. Then cool down phase follows next for about five to ten minutes. While on aerobic exercises, the blood vessels dilate to allow for more blood flow while in coo down phase, the heart and the vessels resume their normal state.

Exercises increase good cholesterol and decreases bad cholesterol. There is a healthy increase in various vasodilators like prostaglandins 1 and nitric acids, and healthy reduction in prostaglandins F2 alpha and norepinephrine, which prevents blood clotting and improves hypocoagulation state.

Exercises improve joint flexibility, bone density, muscle tone, skin elasticity, metabolism, release of various hormones.

Is it not interesting to know that 30 minutes of exercise helps you live longer.
