Everytime I start doing any jumping exercise like jumping jacks, it feels like my brain is bouncing and rocking inside my head...

When I stop after an exercise (p90x), I feel woozy...about to fall asleep

I'm pretty sure this isn't normal...just want to see if anyone experience this or know about this health issue....

Sounds like blood isn't being pumped fast enough to the brain...
