I saw this in a road runner sports mag. and though it was a cool idea but isnt it the same as breathing througha straw? and if so would breathing through a straw help?

Nah, it's not really like breathing through a straw. It trains your lungs to inhale and exhale more air. My Doc hooked me up with them so all I have to do is use it and then write a testimonial. There are 3 levels on the exhale and 6 levels on the inhale (Sport model/blue). I'm on level 2 and i don't know if i'll be at level 3 any time soon. if you could do level 3 you could probably suck your spikes off the floor--that's how tough it is. anyway, i can't tell yet if it's working or not because i haven't hit 6-8 weeks yet, but it has helped me mentally and it does rip up your ribcage muscles a bit (good tone). hope this helped.
