Breathing is very important. "Thank you, Captain Obvious" is probably what you're thinking. But, there is a reason why I mention something that seems so obvious.

First off, weight training, resistance training -- it all pretty much means the same thing, so don't get confused by the wording. Basically, anything that involves the pushing or pulling of something -- be it a dumbbell, a resistance band, or even your own body weight -- falls under the umbrella category of weight or resistance training.

Back to my point -- when it comes to resistance training, there is a risk of raising the blood pressure in your eyes. Research shows that because of something called Valsalva (an effort to exhale while keeping your air passages closed), an increase in blood pressure can occur. The same applies for cardio, although it is rare for people hold their breath while performing exercises of this kind.

Just some healthy advice from your friendly neighborhood Captain Obvious. But before I go, I just want to point out that there were a lot of spaceships in the movie Star Wars. Just something I noticed.
