I have taken the rite descriptions from http://www.mkprojects.com/pf_TibetanRites.htm
The Five Tibetans is neat because it is quick to practise and handy to remember. There are debates as to its authenticity - is it really 2,500 years old Tibetan yoga? Who knows. I don't really care. The book for those interested is called ''Ancient Secret of The Fountain of Youth'' by Peter Kelder.....and hey look! It's online as a pdf.. http://www.lib.ru/URIKOVA/KELDER/Ancient_Secret_of_the_Fountain_of_...
Just to add - don't do these if you have any serious medical condition. Consult your doc if you feel you should. Take responsibility for your own body and be careful with it.....You should NEVER cause strain to your body or breath.
In terms of repetitions, start with a few repetitions of each - three is fine, and very gradually work up towards 21 reps - but really any amount, even much less, in terms of reps is okay, if that's what feels comfortable.
REST between rites when you are doing significant repetitions....pause in Shavasana (lying completely still) or Vajrasana (kneeling back on heels) and let the breath settle and calm. Practice breath awareness.

Lie flat on the floor, face up. Fully extend your arms Along your sides and place the palms of your hands against the floor, keeping fingers close together. Then raise your head off the floor tucking your chin into your chest. As you do this, lift your legs, knees straight, into a vertical position. If possible, extend the legs over the body towards your head. Do not let the knees bend. Then slowly lower the legs and head to the floor, always Keeping the knees straight.

|Kneel on the floor with the body erect. The hands should be placed on the backs of your thigh muscles. Incline the head and neck forward, tucking your chin in against your chest. Then throw the head and neck backward, arching the spine. Your toes should be curled under through this exercise. As you arch, you will brace your arms and hands against the thighs for support. After the arching return your body to an erect position and begin the rite all over again.
Breathing: Inhale as you arch the spine and exhale as you return to an erect position.
|Sit down on the floor with your legs straight out in front of you and your feet about 12" apart. With the trunk of the body erect, place the palms of your hands on the floor alongside your buttocks.

Breathing: Breathe in as you raise up, hold your breath as you tense the muscles, and breathe out fully as you come down.
