No, the title does not mean by alcohol, though I am sure most of you have experienced that type of blacking out before (Guility). Rather, I am talking about that blacking out experience that you may sometimes feel during working out. Many, many weightlifters at some point in their careers have experienced this phenomenon of “blacking out.” This will usually occur during certain lifts where your breath is held for longer than usual for example; squat cleans, presses, regular squats, etc. This is a very confusing process and is very hard to explain. All I can say is that I have for sure felt this before while squatting. Maybe that is why in the beginning prior to joining CrossFit that I skipped leg days all time at regular gyms. I felt like I was going to pass out, I would kneel down and not be able to shake it, felt like the world was in slow motion and this scared me. Though I didn’t 100% completely pass out, and was able to catch myself and take a few breaths to recover, it was still a very scary feeling.
The most common two causes are dehydration and low glucose (blood sugar) levels. Most medical professionls refer to this phenomenon as syncope, as insufficient blood gets to the brain. This can be compared to sleeper holds such as headlocks that don’t allow the proper blood flow to the brain (those of you who use to watch WWF/WWE know exactly what I’m talking about). But of course there are no sleeper holds in working out, well at least not that I know of. So, where does it come from? As I stated before, dehydration and low glucose levels are the main ones.

Hydration is the key to exercise success. When you are dehydrated your blood pressure is lowered (fun fact of the day), which of course can lead to blacking out due to the insignificant amount of blood flow to the brain. Lesson learned, is to stay hydrated during your workouts. H20 is your friend and will never hurt you. Water Boy Bobby B agrees.

You should never train on a completely empty stomach, grab something light to snack on prior. Preferably something high in carbs or sugar to restore those blood sugar levels. These side effects that are shown by the picture do happen, I can 100% attest to it. Feeling weak, thirsty, dizzy, and tired can all lead to you laying on the ground (not in a relaxing way either).

So, as we have learned, make sure your hydrated and eat something prior to engaging in physical activity. Make sure to breath normally between reps and take a big one at the start of a single. Try to keep breathing, I know it is tough during longer lifts but do the best you can. If you feel shaky prior to the movement, just throw the bar down and take your time, breath, and always have a spotter when you can. Now, drink some water, eat some food, and hit the gym. Until next time.
