“I’ve used system for contrast training ExtremeO2 during living at altitude. After sleeping I always fell tired and dizzy and need cca one hour to start with training plan, but after using the protocol Regeneration, I’ve felt immediately fresh and rested and could start with training asap. The same protocol I’ve used before sleeping. I was also very pleased with the result I notice after protocol I’ve made between two hard ascents. I was surprised how easily I‘ve done the second one, lactic acid was lower then normal.”
