I have a very close freind that trains and has chrones. Re has had two removals already of intestine. This is a nasty thing to have, I will tell you what I know he has done.

Diet- has to be very carefull. One piece of lettuce will throw him into major trouble
Shock- Do not knee him in the belly alot, pad or not. I work alot more speed on the techniques than power.

Omega 3 's are very important to sufferers of this.

He has dropped most of the drugs after many years of side effects. If it gets bad again a bag will be eminent.

Watch the pace, work at a challenging pace but be aware some nights it will be tough to go all out, especially if there is a flare up going on.

This is so brutal to go thru, I don't think most have any idea how painfull this deasese can be. In Thailand it would lay him up for a couple of days at a time.

My hat is off to anyone that persiveres thru this to train. Undoughtably a healthy body will cope with deseasse better that not. But for actual fighting I can't say how the stress will interact.
