Coaching Conversations EP8 - What Does Sport-Specific Training Look Like in CrossFit?
"What is sport specific for you as an athlete is dependent on the level that you are trying to achieve." For an Open athlete, sport-specific running means shuttles. At semifinals it means long runs and mixed running. At the Games it means all of it. Ryne and I walked through how to define specificity one movement at a time, and why the stage you're chasing should change where you spend your training. The rest of it: - The three numbers I use to define sport specificity for any movement - Why Ryne will skip an athlete's biggest weakness before an in-person comp, and why that bet fails at quarterfinals - The 2026 Games workout that had Patrick Vellner thinking he had rhabdo - Set size before speed, and the GHD numbers I'm chasing myself - Ryne's four-week plan to get a hamstring ready for a 40-yard sprint - Why athletes feel out of shape right before their best performances Full episode: https://open.spotify.com/episode/2TirD5pKLs0WTm3rXcrA5Z Written recap with every study linked: https://kyleruthcoaching.com/fieldnotes/sport-specific-training-crossfit Two corrections from the episode: the APEX women's bench standard is 115 lb, not 155. Questions and feedback in the comments. If there is a topic you want us to cover, put it here!

@Ryne Sullivan great notes, thank you! Agree that the majority of the year would be pretty basic conditioning on top of strict gymnastics and barbell strength. Especially with the more modern open you need to be more worried about 150 burpees in 9 minutes than you do ring muscle ups. All class members need better strict pull ups and strict handstand pushups. Barbell cycling is stupid until you can power snatch and power clean heavy enough weights. And I hope you like rowing.

@Kyle Ruth I agree that sprinting would be great to incorporate, I just don’t know about the best practices to keep it safe. Also, how fast should someone’s 400/800/1600 be before you worry about true sprint training? If they aren’t top 5 in a more typical distance, should you even worry about shorter distance sprints?
Wall Facing vs "regular" Strict HSPU capacity
Hello everyone! Francesco here, just wanted to share a question that's been bugging me lately. Why are some people better at wall-facing compared to normal Strict HSPU, and why are some people the exact opposite? I myself am more in the second group and can feel a big difference between how many reps I can handle (both unbroken, when fresh, and in a mixed-modal setting) in the two movements. In your experience, is it more a biomechanics problem? with forearm/arm length involved, or is it a muscular thing? like people with stronger upper pecs and pecs in general can use that more on the wall-facing variation... Not sure this is super relevant to overall performance, but it'd like at least to have an idea for what to look for. Thanks!

Wall facing is a bit more of an incline bench style movement. Less balance, less wrist stretch, can kinda cheat it with use of the front of forehead, can get hands really wide because you don’t need to balance as much but feels a touch slower for big sets Regular is the opposite, more shoulder and tricep, but if far enough with hands can really bounce and slide the heels up the wall I feel like wall facing goes away quicker because the muscles involved are used in other crossfit movements, and it’s a longer cookup and cycle so the risk reward is higher

@Francesco Chemello I have pretty little data on it, and they haven’t been tested a lot at the Games for us to make big judgements. A more experienced coach would probably have better info my guess is that some people find when you’re starting fresh, a wall facing strict hand and push-up easier because it is a less challenging position to get into on the wrist and shoulders and it lets you recruit more muscle mass than the typical strict handstand push-up. However, because there are different muscles being used that tend to be used up in other crossfit movements and it is a position that takes longer to get into and maybe requires a little bit more challenging of a bracing position, I think they tend to go away faster and the speed at which you can do repeated reps seems a little slower. For example, if I was going to have a workout where it is sets of 20 strict hand stand push-ups for let’s say three rounds versus sets of 20 wall facing strict hands and push-ups for three rounds. I know that I’m gonna have to pace the workout differently and I’m going to have to approach my sets in the wall facing differently because it’s a much longer kick up and the muscle fatigue feels a little bit more global almost whereas the strict handstand push-ups is more about just making sure that my triceps feel fine. I can kick up and just bounce my head a little bit and then I can kick back down. The cost for those reps and the cost for the kick up is not as bad so you’re allowed to pace the workout a little bit differently. Almost like the difference between Ring muscle ups versus bar muscle ups? Technically both are muscle up, technically both use fairly similar patterns and things, but the cost and risk for performing bar muscle ups versus ring muscle ups is just different even for an athlete who’s good at both pulling movements
Coaching Conversations EP5 - Best Practices Don't Exist Yet for CrossFit
https://open.spotify.com/episode/6BVLwgkZgwvRZ7o5Rg2AQm?si=2BbH386eRZOECjeHf-8V4w Topics we discussed with some related questions. Would love to hear thoughts here - Yielding isometrics build tendon and muscle. Overcoming isometrics build strength. Same hold time, same intensity, completely different outcome. Are you programming "isometric work" as one bucket, or picking one of these on purpose? - Yielding isometrics have a documented painkilling effect — you can hold a loaded position, feel your knees less on the squats that follow, and not have fixed a single thing. Where's the line between smart pain management and masking a problem you should actually be addressing? - Asked point blank if coaching has arrived at best practices for the CrossFit athlete, the answer was: "No — not even close." Swimming's had 50+ years to refine its methodology and elite swimmers are still finding new PRs. What's the one thing you think CrossFit coaching is still getting badly wrong? - Anything under 5 minutes isn't automatically a "sprint" — a 3-minute AMRAP of legless rope climbs and heavy squat cleans looks nothing like a 3-minute row from an energy-system standpoint, even though both are "short and hard." Is time domain the wrong way we're all classifying workout intensity?

The thing that I love about CrossFit is how effective it is. A well done class program, with maybe a competitor extra, seems to give you about 75% world class fitness in about an hour to 90 minutes. The kinda funny thing is that as soon as you wanna push to the higher end of the sport, you almost completely go away from something that looks like that session. To be in the top .0001% you may not even do a “CrossFit” workout every day, or week. The boring answer for “do we have best practices” is probably no, but we can imagine that they will be athlete centered, individualized, and data based, utilizing a team of people to help that athlete succeed. It won’t be any one thing, or philosophy, or sauna session etc. It will be finding people who are genetically gifted and motivated, then working with them to develop against the field for years and years, adjust things up and down, and hope they get lucky. We have some historical data that tells us we need to be a certain speed and strength and skill level, but because the sport is not fixed we have the joy of doing our best to read tea leaves and star charts as to how the fittest on earth will be tested at a given event. That is not a very marketable answer though. It is like the classic coach answer of “it depends”.
Shuttle Runs & Lower Back Pump - Thoughts?
I have a female athlete who is currently competing at Semi Finals level, and I’m looking for some input on an issue we’ve been seeing consistently. Whenever she performs shuttle runs, she gets a very significant pump/fatigue through both erectors/lower back. It seems to be quite specific to shuttle running rather than running in general. Has anyone experienced something similar with an athlete? I’d be interested to hear how you approached it from a programming perspective. Did you modify the shuttle volume/frequency, use different running variations, address mechanics, or do anything specific to improve her tolerance? I’m less interested in simply removing shuttle runs and more interested in finding a way to understand and address the limitation so she can eventually tolerate them better. Any experiences or programming approaches would be really appreciated.

@Kyle Ruth adding onto mechanics, whether she is tapping the floor with the same hand as the lead leg, is she alternating sides with each turn, is she tapping vs brushing the floor etc. Also, how is she warming these up? The shuttle run is kind of unique as it is our only “cutting” movement typically so it can be pretty dynamic if just jumping into it. I used to get pumped out because I think I was trying to be way too fast vs just fast enough. What helped me a lot was doing really boring intervals of like 20/40/60/40/20 shuttle runs with a goal pace that started easy and increased over time. It’s mindless but it helps you understand the Goldilocks speed for the movement. When I warm up I do a lot of low back hinge stuff in the positions of the shuttle, kinda like shoo the cat, just to make sure I let my back know it is gonna be in the position and let it get warm. And then in the workout think about dropping hips, not just back, kinda like if back blows up during db snatches because you are purely bending at the waist.
3 Tips for Better Legless RC
Filmed these on a whim today - I’ve got a lot of athletes prepping for the Games / live events right now so legless are a big component of training. This doesn’t cover the kip touch or basics of leg drive … just 3 things to implement that make I’ve found make a difference. https://youtu.be/pm_wqSQTdj0?is=Yt77hPl6LpOn8tTY

2 things I think about when doing legless as a non elite 1. Fast hands, when my hand speed slows down I know I’m gonna dig a hole that will require a big break, only jump when ready for fast hands 2. Reach far. I practice rope pull ups with hands about a foot apart to get used to covering distance vs hand over hand. If you have time, probably the highest bang for buck if rope climbs are possible is just practicing hitting various top implements to eliminate no reps. Everyone can start a Legless, but no repping the top of a Legless is catastrophic

@Kyle Ruth love the limited pull drill. Regardless of how high you get practice 4 pull or 6 pull etc. When I’m scared I practice a standard climb up, practice 1 hand gripping and touching top with feet, then without, to get over the mental hurdle.
