Walking is probably the best exercise of all for any constitution.

Even for a healthy individual, Ayurveda suggests a workout that is one-half of one's capacity, just until sweat appears on the forehead, under the arms and along the spinal column.

This amount of exercise stimulates gastric fire, improves digestion and relieves constipation, as well as inducing relaxation and sound sleep. Sweating helps to eliminate toxins, reduce fat and make you feel good. Over-exercising may cause dehydration and breathlessness, even chest pain and muscle aches, eventually leading to arthritis, sciatica or heart conditions.

Yoga exercise increases muscular strength, reduces tension and stress, has a low potential for injury, is non-competitive, has spiritual and psychological benefits, and a 5000 year track record.
