Altitude Training Mask? Worth the Money?
I am 17, skinny, novice. I am a pretty skilled martial artist but every time I go up against an mma fighter these guys outlast me. So, I've looked into how to increase my endurance and I'm doing everything most traditional blogs recommend - running, hiit, tabata, etc. Anyway, came across this altitude training mask
that claims to "will help you regulate your breathing, increase lung stamina, lung capacity, oxygen efficiency and increase your overall mental focus. It also helps your overall performance in all sports and daily living." by imitating the altitude training most elite athletes do. Bullshit or worth the $75 to order one of these?
Anyone have any experience with them?
Thanks for any feedback. More noob questions to come.
