HELLO Chris do you think that visualizing at night your sprinting how you want it to be(meaning have extremely fast stride frequency) does it have any positive effect on cns and stride frequency? is there something you can do to make it more effective.Also could you please tell me the name or type of those rubber bands from cal dietzs cocontraction exercises ?

Chris, When you divide up your sprinters into the different tiers, do you go mainly on how fast they run or do you add in other metrics, ie their mechanics and ability to learn, etc? Thanks

Just got a message my track kid blew his 800m and 1500m PRs again! The cats out of the bag now so the ex Olympian coach and team are summoning me! Great fancy LA private school too! Their rivals just messaged me too lol! Your ideas and RPR have been integral! Thanks again!

what settings are you using? it looks like a hard ecc? The video i watched in on your work out for this upcoming week.

Hi Chris! Thanks for all your great feedback! Really helps! So I’ve heard you mention the slant board a few times in your material and of course a sucker like me has one lol! At least I got the knock off one on Amazon lol. So I’m just curious how you set the fulcrum underneath to get the right spring action?! Love the tool in general and has been helping a lot of clients to in a lot of different ways! Thanks!
