do in Formula One in Aerospace so they use differential pressure instead to to quantify the flow of what you're doing so basically this is a device that just sits here it's a headgear there's no wires there no nothing it's basically connects to your phone watch whatever that you have and then basically this is how you now collect your oxygen consumption so I could go out for a bike ride if I'm going to go and do V2 Max intervals and hill repeats my favorite workout is the four to five minute Hill repeat I could be wearing this thing and that's it and I come home and it's going to say if I did 10 sets it's going to tell me Peak oxygen consumption for each set
