I heard somewhere (and it could be wrong) that yawning is caused by a lack of oxygen to the brain and is the body's way of getting more air into the lungs. If this is the case, make sure that you are breathing properly.
I cant stand it. I went to the gym this morning after getting 9 hours of deep sleep. The second I am done with my second set of flat bench presses, I start yawning like crazy. It seems that I yawn throughout my workout, the same amounts whether I get a lot of sleep or not. Any ideas on why?
PS I eat a light meal of 4 egg whites, 1/2 cup of fiber one cereal and 1/2 cup of cottage cheese with my vitamins, then wait 1-2 hours and run to the gym.

NOW THAT EXPLAINS A LOT OF THINGS!I heard somewhere (and it could be wrong) that yawning is caused by a lack of oxygen to the brain
Maybe I am just winded being so fat.
I will pay more attention to my breathing. thanks


Could be you are not sleeping right. Maybe you think you get deep sleep and do not. Could be sleep apnia.

I yawn alot too, never thought of it before though. I have really bad allergies so I have breathing problems sometimes. Maybe that's why.
I used to have the yawns when doing legs. That stopped after I quit drinking a shake within 1/2 an hour of going to the gym (my workouts improved too since I didn't feel like I was always going to yak).
It is usually an oxygen issue. 1-2 hours should be plenty of time before you lift though.... Have you noticed if it occurs more if you eat with less break before lifting and if you yawn more in doing bigger body parts (legs, back...)?
I may not be very bright...but I think a lot.
yawning is common in lecture...
but never in gym
Thats funny that you mention that because I have already been diagnosed with sleep apnea. I have the machine and sleep like a baby. Maybe I need some adjustment now that I have lost 40lbs.Could be you are not sleeping right. Maybe you think you get deep sleep and do not. Could be sleep apnia.
I just yawn, but do not feel tired. I lift good amounts and feel energetic. its just annoying, it is not anything that is ruining my workouts.
meh, who cares?! as long as you're not physically tired i don't see why it'd be a problem... you say it's annoying but am i the only one who thinks a good yawn feels good?!

Maybe not multiple times a day though, that could get tiring. I yawn sometimes also, strangely at the gym, I have also heard the oxygen issue.

Here are some articles that explain yawning.

YAWN.......
Not to minimize the Apnea issue as that can seriously affect energy levels and ultimately performance but i would be inclined to think it is more of an oxygenation issue.
I would recommend you boost your cardio-respiratory fitness by doing some cardio work on a regular basis. Your body will become more efficient with oxygen transport and delivery so you will get more blood to the muscles and more oxygen will be extracted from the blood into your muscle tissue etc...
I've seen this phenomenon before and cardiovascular conditioning often makes it better.

i do 30 mins of cardio 6-7 days a week. i know this is a lot but i am an obese guy that has a high fat percentage. maybe thats why i yawn so much.I would recommend you boost your cardio-respiratory fitness by doing some cardio work on a regular basis
Well , if you are very over weight as you say, then I’m not surprised you are having these experiences (both yawning and Apnea)
Keep up with the cardio. Don’t wear yourself out right off the bat, build stamina and endurance and lose weight gradually. Keep doing your weight training. More muscle = quicker metabolism.
I’m glad you are taking charge of your health. Takes a lot of work to re-invent oneself but well worth it.
Good luck
