Are you staying hydrated? Are you eating a good meal at least a couple hours beforehand?

Lightheaded means not enough oxygen to the brain.

Two common issues..

Holding your breath. You literally use up the oxygen bound to your hemoglobin and since your lungs aren't supplying more, your oxygen levels go down.

Bearing down inappropriately. This is called the Valsalva maneuver, in which you tense your abdomen like you're trying to shit. This stimulates the vagal nerve, which is the "brake pedal" for the heart. Heart rate goes down, blood pressure goes down, you get lightheaded. Hydration can help with this.

But, this is an internet forum. If you're 100lbs overweight, you should really see your doc and get an ekg, a stress test if indicated and some bloodwork before jumping into a hardcore workout program. Ask him about the issues you're having.

Not normal. It's typically a sign of low blood pressure. Could be dehydration, or some chronic condition. You might check with your doctor.
