I chew gum everytime I workout. When you chew gum when you work out, your mouth is constantly open and your taking in more Oxygen, which is need to feed your muscles during intense workouts. O2 is energy, energy means more intense workouts. With your mouth closed, your inhaling through your nasal passages which is alot smaller then taking it through your mouth. That's why the gum helps you take in alot more oxygen.
When I seen these, I had to try them. I'm hooked. I got my gum and as a bonus, a RUSH when I workout. I can by tired as a dog coming to the gym on a Monday but pop 2 of these and I'm ready to load the bar and rep out 315 for reps.
I've searched high and low locally and it's very difficult to find ENERGY GUM. There's tons of energy mints but I want Chewing Gum! Good thing Chemical Evolution carries them, and for a kick ass price too!
