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

It really works very well

The quality is there, this mask is well constructed. Keeping things succinct, I have found this mask to make breathing during workouts “fun”. Specifically, it helps slow my exhale, and that is right now paying dividends. I’m on the second to lowest level, and intended to take it slow from the get go. What I have done, that was initially unexpected, was to expand its use beyond weight training to include my HIIT and even my Yoga/stretching. It’s not the least bit painful, nor is my breathing labored. What it does do is make me “think” about my breathing like never before.

I’ve been using this training mask during my cardio and cycling workouts for the past month, about three to four times a week. I’m pretty familiar with this type of gear, and overall, it’s done a solid job to date.The adjustable resistance levels make it easy to scale intensity. I could change settings mid-session without stopping, which helped keep things flowing. The mask fits securely and doesn’t slip while I’m moving around, and it’s comfortable enough, even during longer workouts. That said, I’ve used a couple other masks that felt a bit more snug or better-built. This one isn’t far off, just not quite at that level.I started to notice better breath control after a few sessions, and I don’t tire out as quickly on regular runs. It’s also easy to wipe down and keep clean. If I could rate it 4.5 stars, I would. It’s a great option if you’re looking to push your breathing a little harder during training. If you’ve tried other masks before, you might feel the difference, but for most, this one will do the job well.

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

Great mask. Tight fit. Settings for starters to experts.

It can help restrict air flow to aid maintaining a higher heart rate. On the higher levels, practically impossible to breathe in.

It works as advertised, love it. Just be careful and dont get ahead of yourself. Take your time to get used to.

Product simulates breathing through a straw and does NOT simulate altitude. Benefits and claims of this mask, and others like it, are not backed by scientific evidence. Waste of money
