Being a Student of the Sport
https://open.spotify.com/episode/1YP4ZFqQPXU75Ht5nn7PSS?si=FTmzvVSTRnuIXElC73aCpg This week Kyle and I talked about why the athletes who study the sport keep improving long after others stall out. We covered: - Why every new technique feels terrible at first. - Why you should review video during the session instead of that night. - How to model your movement on athletes with a similar build. - How a single movement can quietly cost an athlete their whole competition weekend. A couple of questions for you: 1. What’s one technical change you or an athlete made that felt awful at first but ended up paying off? 2. Coaches, how do you find an athlete’s real limiter? Do you go by competition history, testing, or what you see in training?

Coaching Conversations EP12 - The Less Time You Have, the More Specific Your Training Has to Be
"The less time you have, the more specificity is required. The more time you have, the more you can broaden what you're doing." A lot of my clients are going from two 90-minute sessions a day to 60 minutes, and they still want to train like athletes. Ryne Sullivan and I went through what changes when that athlete gets five 60-minute sessions a week. The rest of it: - Why a high training age is an advantage when time gets short - The skill work I cut first for time-limited CrossFitters - Two supersets that don't fight each other, and the pairing Ryne never uses in a strength phase - Where Ryne and I disagree on adding intense breathing to strength days - Why two 45-minute sessions beat one 90 - What "you have to earn the right for it to be metabolic" means for your training - How Jake Berman won a 200 wall ball workout doing smaller sets Full episode: https://open.spotify.com/episode/1PoeZmyVVJ59itwKV9nixA Written recap with the workouts: https://kyleruthcoaching.com/fieldnotes/training-with-limited-time Two corrections from the episode: Fran is thrusters and pull-ups (I said chest to bar), and Elizabeth is cleans, not power cleans. Questions and pushback in the comments. If there is a topic you want us to cover, put it here.

I also want to point out that I disagree with the sentiment that a clean is automatically a squat clean, I believe it is a choice. There is no requirement to pass through a squat in olympic lifting and if we are going to allow people to use the more efficient version in every other movement unless modified to make it harder ( a ring muscle up is kipping unless specified on how to perform it - strict), we should allow the more efficient version of a clean. At 135/95lbs, that is objectively a power clean and likely a muscle clean for the upper level performers Fun episode though
Coaching Conversations EP11 - BFR Training Isn't Just for Elite Athletes
"There isn't one single population where I'm like, it's only if you've reached the semifinal CrossFit level that you've earned BFR. It's just another tool like a barbell or a leg extension machine." BFR lets people build strength and muscle at lighter loads and lower volumes, which is what most of the exercising population is missing. I use it with everyone from 60+ masters athletes to Games athletes, once they've been screened. The rest of it: - the cuff placement mistake I keep seeing from people who teach BFR - why I keep the cuffs inflated through the rest, and what my endurance athletes said after resting in cuffs between heavy sets - the study where world-class rowers took seconds off their 2k with four weeks of mostly easy rowing - why classic hypertrophy work can make a CrossFitter's triceps fail sooner - IPC, and Ryne's pushback on whether cutting muscle damage blunts adaptation - the six-week on-ramp I use before any BFR strength work - manual vs Bluetooth cuffs (stick shift or automatic) Full episode: https://open.spotify.com/episode/7yVeNI98DJmGZcpGsN47lk Written recap with every study linked: https://kyleruthcoaching.com/fieldnotes/bfr-training-not-just-for-elite-athletes Two corrections from the episode: - I ranked "cuffs inflated during the sets, deflated during the rest" as the worst option. The research doesn't back that ranking: inflating only during the sets, only during the rest, or the whole time all produced similar strength gains in the lab. - The IPC training study I mentioned used knee extensions, not squats. Questions and pushback in the comments. If there is a topic you want us to cover, put it here.

I thought that I had read the BFR research on similar strength development So given that, how would you (if at all) change the prescription for athletes? I ask this because I have athletes deflate between sets so that I can use the cuffs for more accessory work exercises when looking at total time with cuffs on but I wonder if that might be misguided
Blog Post
I wrote a blog post on the differences in running on the road and the air runner and why each favors a different profile of runner. Would love to hear anyone's thoughts or experiences with this nuance of running https://coachrynesullivan.blogspot.com/2026/10/the-air-runner-and-road-reward-two.html

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.

@Nick Cole-Butler I have never done formal track sprinting but I do know that the University of Houston, an elite track and field program only does the warmup for the first week of the season. So I have to imagine that the ramp period is VERY long As far as quarterfinals, this is a complex topic. I have some initial thoughts but I would formalize it but here are some known tactics I would use with class 1. Strict gymnastics strength development from May until December - this is one of the biggest separators at the open and QF level. I would want my kipping technique work as extra credit but have clinics available throughout the year 2. Absolute strength development year round with olympic lifting technical emphasis from May until November. Then increase loading in strength work through the end of December before bringing it into metcons 3. Engine development. I like to take a bit more of a shotgun approach with class. I think that if you can let go of "strength + metcon" you will see that a lot of class members are very open to a 40 minute emom. The short sprint power work work I would try to limit to no more than 2x per week with one of those being VERY short. Then mix intervals and true metcons. I tend to gravitate towards simplistic movements in metcons throughout most of the year (rowing, burpees, double unders, lunges, wall balls, thrusters, power based oly lifts) but as quarters approaches you have to take people through more complexity if you truly want them prepared. My preference is to have a QF track that takes the same workout and layers in that complexity while still participating 4. Skills practice as a buy out so that your top athletes can do ring muscle ups, HS walks, GHD sit ups after class without negatively impacting the next class 5. Emphasize fun in the class... people who are excited to train get more out of it and show up with higher frequency. The simple reality is that in order to perform in quarters, you have to have some base level of volume
