Things to watch out for
While you are exercising, you might get a headache, chest and joint pain, cramping or high blood pressure.
These may be signs of mild dehydration or poor nutrition, or they may be symptoms of something more severe like autonomic dysreflexia.
Other warning signs to watch for are profuse sweating, blotching of the face, neck, chest and arms, nasal congestion, and dilated pupils.
DO NOT ignore any of these symptoms.
If you get any of these symptoms, stop the exercise session and talk to your doctor about them before you take it up again.
