You made a comment about seeming to stumble out the blocks … And I watched your video of your sled runs several times… You look very good and strong but I noticed your arms are too far back and not helping you the way they need to.
If you stumble ever out of the blocks it can be because your have more power than you are able to convert at this time … this is good news.
So now I want to understand a bit more about your arms?
We spent a great deal of time doing arm drills , I did a ton of arm pulls, and I started paying a lot more attention to using my arms in the drills. I don’t know exactly what to tell you do but I see for sure that when you are able to get your arms ( which appear very long which is great physiologically speaking) out in front of you more so you will be able to utilize the strength and power attributes you have already developed.
Have you done many hills? Hills can be very helpful in developing the arm action because you can feel the arm action in a more pronounced way.
