If you've ever thought about using recreational oxygen to boost your CrossFit performance, you'll appreciate this message from CrossFit Games Competitor Jeremy Herider. After competing in the Masters 40-44 Division, winning event number four and placing 12th overall in the 2013 games, Herider began using Oxygen Plus (O+) pure oxygen (formerly Oxygen Factor) to improve his competitive prowess.

Watch the video below to see how Herider used oxygen for CrossFit. Herider says that he uses O+ during heavy lifting, breathing 10 breaths before his workout and then breaking to take three breaths in-between each set.

"What I've noticed is, my power is constantly there," Herider said. "My mental side - the alertness is there. I feel fresh. I feel fresh going into every single set."
