I hope this is the right forum for this topic. I was just wondering if anybody has ever had any experience with this product. It really sounds like it would be something that I would want to implement into my running routine. My other question is if I started using power lungs for a period of time then stopped would the benefits I recieved from it stay with me as long as i kept on running and doing other cardiovascular activities?
