If you are wanting to "elevate" your workout, this is the tool. Be warned, you will feel like you are dying at first, but you get used it. Sort of.
1 of 1 found this helpful This is a great product. It does not necessarily simulate elevation training, as many factors go into that, but it does decrease the air flow and increase heart rate. You work in a max cardio zone longer, quicker - which is why I purchased it. If you go for a 45 min session, be prepared for your lungs to actually feel sore the next day or so.
