Can you be a little more mature. Funny how ballsy everyone is typing on a computer. I already said, for the third time, I don’t use them nor would I recommend them. As for there being instances where running on them is better than nothing, see above post. As far as knowledge, I have learned a great deal from Charlie, IN PERSON. Like I actually paid him, not just get as much free info as possible from the forum. I believe in CFTS. I don’t pretend to know all there is about the subject. I just think I will stick to what I know. I have my share of fast athletes. I venture a guess that perhaps I have trained athletes from Olympic sprinters to NFL football players, but according to you and fogelson, I need to hone my knowledge. I will continue you to. Gain, this forum is an exchange of idea’s. I disagreed with the treadmill, but in doing so, didn’t need to hurl insults to get my point across
