Blood pressure or possibly low oxygen level in your blood due to working out. just my guess.

Don't hold your breath. Inhale going down, exhale coming back up.

Quote HistoryQuoted: Don't hold your breath. Inhale going down, exhale coming back up. You don't valsalva manuever. No way I'm squatting anything over 80 percent and not holding my breath. Breathe between reps. |

Have a partially torn shoulder and more than once overworking it triggered some sort of vasovagal response and my BP bottomed out.
Not from pain, just hit the right combo i guess. Not instantly but like a minute later. Scared the wife once when I was sitting there holding my water bottle but went unresponsive for like 15 seconds...  Learned not to overdo it from now on. |

Quote HistoryQuoted: Don't hold your breath. Inhale going down, exhale coming back up Dont do that. Holding your breathe allows you to tighten your core, considering that your core is the thing holding all that weight.. a tight core is important. |

Almost? That's not giving it 100%. Just joking, I feel light headed once in a while also. I think it's from holding my breath.

Inhale going down, exhale at the top  The light headedness is caused by lack of O2 and the drop in BP which occurs after your set. Your muscles require more O2 for heavy lifts, but since you're holding your breath and working hard they can't get it. The heart tries to pump more blood to compensate, thus increasing BP which then drops / returns to normal after your exertion is over causing the light headedness. It's a sign of a good set. |

Should be drinking 2/3 of, or up to a gallon of water every day. |

What’s your blood pressure typically?
Do you have this issue at any other time in your life? Make sure to “hold” your valsalva in your abdomen, not your head. I exhale (grunt) as I get to the top and that seems to help dizziness. Edit: The reason I ask about this issue at other times in life is that if you routinely feel dizzy after exertion, you might need to see a doc. |

Holding your breath with the load on you ramps up your blood pressure. Then if you release under a big load your blood pressure will drop huge amounts. Don't release your breath until the pressure is off.
This happens to me on deads that I don't get up and put a lot of effort into. |

When you hold your breath, you increase your intrathoracic pressure (the pressure in your chest). THe aorta is a big, thick vessel...it carries blood away from the heart to the lower body. THe inferior vena cava (large vein that carries blood back to your heart from the lower extremities) is thin. WHen you hold your breath and exert yourself, you collapse the vena cava, so that blood can't return to the heart and your blood pressure drops. DOn't do that.

Orthostatic hypotension here. Nearly passing out after a heavy set has somewhat become routine for me. Inhale big, valsalva, drop into the hole, exhale at the top, rinse and repeat, rack the bar, hold onto the cage and enjoy the pretty lights.
Had a tilt table test done at the Neurologist, I failed it in spectacular fashion, 36/24 and was still mostly coherent. It's just one of those things I just plan for depending on what I'm doing. With squats I can stabilize myself with the cage, deads, I just make sure my landing area is clear. Semper Fi |

it happened to me fairly regularly last year, i would always rest my arms over the bar so i wouldn't drop and knock myself out. would typically see gray static in my vision.
this year for some reason it happens very rarely and I've been doing a lot heavier and more often. |

Quote HistoryQuoted: Don't hold your breath. Inhale going down, exhale coming back up. Jesus, don't listen to this. Belly breath in, brace, hold, squat, release after you stand all the way back up. Google powerlifting "bracing" and the valsava maneuver. |

Strain against a hard squat for 10 sec or so while holding valsalva and yeah, you will probably risk loss of consciousness. I would argue that a brief loss of blood pressure, say 5 sec or so to complete a hard lift, isn't going to come with any significant risk. Not using the valsalva has some real risks though, like herniated discs. How much are you guys squatting while breathing? I can do it with 3 plates probably, but 4 or 5 would probably end with me in a wheelchair. |

So, every elite powerlifter and weightlifter in the world is wrong? Men squat 1,000 pounds using the valsava maneuver. How are they still alive? Stop taking about things which you are ignorant. |

My breath is held for the first couple of inches of upward travel then I begin to exhale. My post about not holding your breath was directed at people who hold their breath for the entire movement. Full travel down and back up. We love to make fun of the Lunk Alarm at Planet Fitness going off because people are grunting. What do you think the grunting is? |
