Today’s podcast guest is Andrew Iselin. Andrew is an Australian sprint and hurdles coach and head coach of AAA Squad in Brisbane. He’s coached athletes from the junior ranks through to the Olympic level, including sub-10-second sprinter Lachlan Kennedy and Australian representative Calab Law, with a strong reputation for developing speed at the highest level.
In this episode, Andrew Iselin joins me to discuss athlete development, sprint coaching, and the value of exploration over rigid technical models. We get into developing Lachlan Kennedy (9.85s 100m dash and Oceanic Record), coaching asymmetry, relaxation and sprint mechanics, game-based speed work, movement literacy, resisted sprinting, tempo training, and why coaches may need to “shut up” more often and give athletes space to self-organize.

Andrew Iselin Quotes
“Yeah, definitely in Australia, we’ve got this little athletic system and that system almost makes kids try every single event because they’ve got weekly rotational programs. So it’s really good for their fundamentals development to take place.”
“The thing is with over-queuing with kids with ADHD and the like, you know, they just forget. So you’ve got to sort of be deductible.”
“Yeah I really didn’t like the long slow running so I broke everything up a lot and sort of took decent breaks between sort of shorter reps and that way I could keep interested”
“Well, exactly. And it’s also just letting those athletes explore, giving them sort of little simple cues or little simple things to try and do during a session and just getting them to come back and tell you how that felt and then booking yourself and seeing if it’s made any of a difference.”
“It’s so athlete-specific as well. There are some athletes you can sort of say a cue that does not work for anyone else and for some reason it just hits home with them. So that’s why I like to sort of just play around with things with different people um see what sort of reaction I get and a lot of times it does go bad and you’re like well don’t think about that”
“People create compensation patterns for limitations, like myself. I’ve got right side limitation. I created patterns to actually work with my disability. And whenever I tried to make it symmetrical, I’d get injured.”
“So over time, I’ve just, I’ve learned to shut up. I learnt not to just say something for the sake of saying something”
“I don’t like to put too many limits on the athletes, especially when they come up with a suggestion and they want to actually give it a go.”
“But it just goes to show like someone can try every event, But if they’re not allowed to actually properly explore themselves, they just become this robot for each event they do.”
“Athletes are so individual like shouldn’t we just be looking at movement quality and determining whether it’s too much resistance based on that”
“I’m all full tempo. I love it. And it does allow you to, at a sort of safe aesthetic, explore a little bit more as well.”
