Rising onto your tiptoes is a pretty good aerobic exercise. It can not only keep one's heart rate at around 150 beats per minute, allowing the blood to supply the cardiac muscle with enough oxygen and benefit one's heart and cardiovascular health, but also exercise the calf muscles and ankles, preventing varicose veins and enhancing the stability of the ankle joint. Most importantly, it can avoid knee injuries, which makes it a pretty good way of exercising for many elderly people who don't have very good knees. Walking on tiptoes: walk 30-50 steps each time to tonify the kidney in order to feel slightly rested, then repeat several sets according to your physical condition. The speed can be self-regulated, feeling comfortable and relaxed being preferable. Beginners can lean against the wall, whereas after becoming proficient you will no longer need external support.http://www.lige8.com/ Sitting while rising onto your tiptoes: Keep the knees and thighs level, place two bottles of mineral water on your thighs and perform weight training, rise onto your tiptoes 30-50 times each time, and self-regulate the speed. Lying down while pointing your toes: When resting in bed, bring your legs together and stretch them out, then point and relax your toes. You can do both feet at the same time or practice with one foot. If your calves feel uncomfortable, stop and rest. Do this 20-30 times. Standing while rising onto your tiptoes: Place both feet together on the ground, forcefully lift up your heels, then relax. Repeat 20-30 times. Although the method seems simple, its fitness effects are pretty good. When you rise onto your tiptoes, the amount of blood squeezed out by the contraction of the posterior muscles of both calves is roughly equivalent to the amount of blood pumped by the heart per beat. iddy0002
