Headaches

can anyone tell me why i get these crazy fucking headaches when i try to do something really tough, like chin-ups? they're pissing me off

Maybe not breathing properly? Howz the diet? Do you get it every time? After how many reps/sets does it happen?

it always happens the very first set but gets less painful by the 3rd one after i rest a bit. yeah, i get it every time i do chin-ups. i dont know about breathing. how shud i do it?

Should be breathing in on the way up and out on the way down. Don't hold your breath...
Sorry that's all I can think of...

i'll try that but can it be as simple as that? breathing in and out. i mean these headaches are killers, but they last for like 20 seconds at a time. might it have something to dow ith blood pressure? hope i' m not the only one getting em

you might want to get your neck checked out by a physio. My wife is a Physio and most of the headaches she treats are neck related. You may have trigger points or tight surrounding muscles that are causing the headaches...especially with your arms stretched overhead.

I agree with Jugger0, had same problem. Turned out to be some old rugby injury that healed "skew" Fisio fixed it, give it a try!
