Sparthos High Altitude Mask - Simulate High Altitudes - for Gym, Cardio, Fitness, Running, Endurance and HIIT Training [16 Breathing Levels]

The seal sucks, it isnt tight and it lets air flow beside the nose where it shouldn't. I dont like air shooting into my eyes. On the plus side it looks cool.

When I received the mask the first thing I did was to read the instructions and clean the mask. Next I tried the various levels of the mask to see at what level I could start with.So I inserted the other insert into it's slot set the level to 1. I set the timer 2 minutes and just a simple march in place a low intensity pace. I must be honest it was a difficult time to be able to keep the mask on during the march the mental idea of the mind thinking I can't breathe. That told me to take it slow into progression to set my goals to reach at least that level.From there I started with single insert on level 1 for 20 minutes without any activity just to get use to the idea of the use of the mask. Then I progress to an evening walk with the mask for 20 minutes on level 1.Each day I would increase the level same walking in the evening for 20 minutes until I reached level 4 single valve. Took the 4 days to reach level 4 single insert.I progressed to walking 2 times a day level 4 single insert. 1 in morning and 1 at night 20 minutes each for a week. I find that it is low intensity walk that I'm able to stay at level 4.Now I started more intensified cardio and cross training at level 4 single insert for 20 minutes.I have noticed I have a more difficult time maintaining level 4, I have to adjust down the level as I'm going along. This tells me I just have to keep my efforts there with time I will get there.This is where I'm currently at with mask and I will continue to work through at 20 minutes and progress to maintain a level 4 on single insert.A little background of myself I'm a 54 year old active male. Running was my passion I use to long distance run and marathons both full and half marathon. I also did hiking and biking activities. Now I'm doing short distance running and more strength training exercises as well as cardio classes and boxing workout. The mask intensify my workout more. I see where this will improve high intensity 1 hour cardio classes.Even though I ran long distance, I was pacing myself, I found myself transitioning to a 1 hour cardio classes can be difficult, because of the constant intensity movement can leave you winded. Unlike run where you pace yourself or walk for the moment.My advice to anyone that is just beginning just like me no matter what your fit level is to do a self check see what level you would need to start with (your starting point).Don't set your expectations to high for disappointment to wind up giving up.Start off slow progress your way up.Give yourself time to adjust to not lose site of your goals. Also want to mention is to remember to just have fun not just in the use of the mask but in anything you set your mind to do.I myself learning more of myself as I'm transitioning to a different way of fitness for myself.Take careEnjoy whatever you set out to doHave fun with all that you doBrian

I ordered this product because one of the parts of my elevation 2.0 mask got jacked up & they didn't offer replacement parts so I thought to give this mask a try.. I went running with it today & honestly it was the worst thing imaginable. I've wasted money so now I'm genuinely pi**ed. It isn't as secure as the Elevation Mask & doesn't fit as securely. If you're serious about running in a mask &/or actual sweat/jarring factor, I wouldn't recommend it.

I purchased this mask to train for the Spartan Beast race (nicknamed the Soul Crusher) held on Big Bear. I knew i needed some help with my breathing at such an altitude and this mask delivered! Being closer to 60 than 50 now I wasn't sure about completing the 12+ mile race. While I sure want the fastest person on the course, i did complete the race and have no doubt the Sparthos Training Mask helped me reach my goal!
