Rebounders are FANTASTIC.. any jumping motion, even walking, stimulates the lymph glands and helps to remove waste. The colon is stimulated, as well. My boyfriend does this neat trick for his colon that he heard from a health expert -
Suck in your stomach as MUCH and tight as you can and lean over. Stay this way for 10 seconds.
His colon is so clean the food he eats leaves him after 2 hours [he's a raw foodist].
Have you considered the raw food diet?
.. anyway, yes, plenty of water and exercise. Rebounders are the absolute best. Yoga, too, has fantabulous results.
