Hi Tony. Yes, if I'm mentioning a Francis in one of the videos, it's most likely Charlie. My apologies if there is confusion in the vid, that I state Charlie as part of Tellez's tree. That was not my intention. I'd have to go back in and look at the context of how I'm referring to Francis, but I realize that they are contemporaries and competitors as coaches from the same era. I was prolly most likely rattling off those favorite coaches of mine that I'm aware of being from the Tellez tree, then immediately segueing into something about Francis. I'd consider Tellez and Francis to be equals and both genius track coaches, even if one was unlucky enough to have his highest profile athletes busted at the most high profile time. At some point in the future, when I get time, I'd like to redo these vids by taking out all of the rolling text and putting the info back in through my spoken voice ... but I haven't found the time to do it yet. Hope all is well with you, Brian.

Thanks Tony, that means a lot coming from you. I've learned a ton from your online resources. Thanks again for all your efforts and work with coaches education.

Thanks for the good words Leon. In my video on this channel about my opinion on how sprinters should approach the Olympic Lifts, I address my thoughts on how to execute the first pull in order to put the hamstrings in a position to elicit the pre-stretch/reflex, making sure not to de-train the reflex in the most explosive movements in the weight room. Otherwise, in other exercises, I would emphasize exercises that focus on the eccentric, and perform a majority of these exercises in single support. We don't do much stuff that is concentric and double support with the hamstrings ... really only physio ball stuff with the heel(s) on the ball and the Nordic Knee Ext. We use a double support deadlift very sparingly and only in early season, but we do single support DL and variations on a regular basis. We also do our lunge walks in a specific way to make sure the movement is hamstring/hip focused. The only exercise that we'll use throughout the season that is double support is the Nordic Knee extension, focusing on the descent and not the curl back up. If we do get on the ham curl machine it is to do a "2-up 1-down" eccentric movement.

alright, thanks a lot! The video makes a lot of sense (also with what I've read prior about all this). Do you have any particular 'on track' exercise to help with training the correct movement in order to activate the stretch reflex? (other than the usual skips etc.)

Daniele, thanks for the good words. For about a year I had plenty of time to make many of these videos. I now have a lot less time to make them unfortunately. I have ideas and plans to make others on a variety of topics, but just not the time recently. Starts and drive phase of short sprints and runways is something I'd like to put out there, and will try when I can find time. Thanks again. I believe I have some vids in my "liked" and/or "favorites" section that I'd recommend.

asafa brings knee forward too early usains max speed tech is more accurate

Chris, thanks for the good words. Glad you like the vid. Unfortunately I do not have a better version of the video of Asafa's race.

Jayxus, sorry for delay responding. If you haven't found the songs already ... I used Carly Comando's "Everyday" and/or "Bear" on most of my videos.

They have a kid named Mondo that might make you change your mind LOL
