The Bas Rutten O2 Lung Trainer- Devin Castille Review

“Training with the Bas Rutten O2 Lung Trainer has allowed to elevate the intensity of every workout beyond any routine on its own.

The quality of my workout is increased which has increase the my athletic performance levels. I have noticed a faster increase in my speed, power and endurance by using both the O2 Lung Trainer and Mass Suit. Training without them in game time scenarios have now slowed down allowing me to focus and get “into the zone” easier because my physical wind and strength levels are above and beyond normal”.
