How can I stay lower in my sprints? I am hitting 1.78 first 10 meter but I feel like I’m popping up.

This is a sub-11 athlete, have seen him go 10.2m/s with assistance in flats over 60m so he moves decently. That said, watching his stride he regularly varies between actually creating excursion and sweeping (in this video his left sweeps) but his right punches straight down. If focuses on sweeping he either does both legs and slows or alternates. Thinking it’s core/hip related (I think I detect torso movement backwards when sweeps). What do I do to get him working both legs properly?

Korfist & Caleb, Great job on the 08/13 new coaches video. Even for an old coach, it was refreshing and informational. To me it was interesting to hear Korfist's more in depth philosophies in coaching and the execution. Caleb - great questions from a young coach. Keep it up.

This is for everyone. Thinking both the private sector and the school sport team. What message / how do you convey the ideas & methods of the training that we are learning here, since they are not like every other training that historically runs athletes into the ground to "get faster"? Even after a few weeks they see results, yet they think they should be doing more of the other type of training and not want to invest the time on the little things that matter. What are some of the discussions to help sell the path they are on?

His acceleration looks like a leg cycle rather than more piston like action on his first initial steps. Can you explain what’s going on here? Strength issue? @Chris Korfist
