Let's start by looking at exercise hemorrhoids that work, and also promote a good bowel movement.
That is simply "walking"
Walking is the best exercise you could do to stimulate your bowels to work properly. You only need about twenty minutes, three times per week. This would be the very bare minimum. Ideally you should try to add a ten minute walk on the other days.
The walking does not have to be done on marathon time, just easy medium walking is suffice.
SIDEBAR: If your bowel movement is regular and easy, then there is no pressure on the anus, and walking helps in promoting such a bowel movement. This confirms that walking is a good exercise for hemorrhoids.
Another excellent tip is to walk inside the house for a few minutes, just before stool time. The movement tends to help loosen the stools.
One more tip I would like to mention here. This was given to me by a good friend of mine.
That is to do PILATES Exercises.
Apparently through pilates, he learnt how to use his stomach muscles, to evacuate. This avoids pressure on your rectum and it means that pilates must also be a good exercise for rectal hemorrhoids.
I must mention here that I have never tried this pilates exercise myself. Therefore on this one, I cannot personally vouch for, but the principle behind it certainly makes sense.
Exercise hemorrhoids that don't work is everything else. If you are experiencing a bout of hemorrhoids at the moment, then all other exercises are no good for you.
This is due to the fact that the extra pressure on the anus, caused by the various exercises would deteriorate the hemorrhoid further, causing you even more pain.
When your hemorrhoids are gone, then you may do any type of exercise. You need any type of movement, to help the bowels work properly.
However walking still remains the best overall.
I would also like to point out that caution must be taken at all times with exercises like weight lifting.
