You wrote a short article (in the LiveSpill?) 1-2 years ago describing the 3 ways to use a sled. I loved that article and want to read it again for tips but can't find it. In that article, you said something to the effect of sprinting as fast as possible is best for conditioning, moderate-paced speed focusing on muscular contraction is best for hypertrophy, and I can't remember the 3rd. I also can't remember duration or length of the pull/push or any other tips you gave. Can you expand on this and fill in where my memory has failed, please?
Thanks in advance!
