Conjugate Method in Crossfit Training
Hi everyone! Hope you’re all doing well! Does anyone have recommended materials about the conjugate method for CF training? I tried to search online and there are a lot of information already but I don' know where to start with. For example: 1. What does the max effort in conjugate training normally means? 2. How does then conjugate method apply to different types of CF athletes? I'd highly vote for having one of the office hour or the Stimulus Podcast discussing this topic. Cheers!

There is no reliable info on conjugate in CF outside of podcasts that I have come across. At this point most of what I've found to work has come from personal experimentation with myself and clients. With that said, I'd strongly recommend reading the Westside Book of Methods. It does a great job of explaining the "WHY" behind the methods - which you can then extrapolate to CF. Basically there are 3 "methods" (or types of training) Max Effort Method - essentially building to a "daily max" in a movement that high transfer of training effect to the target movement. For example if you want to improve a back squat, you need to choose movements that will lead to direct improvement in squatting strength in some way. Typically rotations are: build to max effort: 5, then next week a 3, then a 1-2, then deload and repeat the cycle -- this works for EXTENDED periods of time to drive the "neural" side of strength. Repetition Method - this is essentially a hypertrophy style of training - targeting the primary determinants of muscle growth (creating local fiber fatigue --> mechanical tension --> growth) Speed / Dynamic Effort Method - this focuses on building the "speed" component of absolute strength. One big factor in being able to move heavy weights is your ability to produce force quickly (aka rate of force development). The speed / dynamic effort method uses lighter loading (60-75% ish depending on the lift / the lifter / etc) with the intent to move the load as FAST as possible. I talked about all of this a bit in 2-3 episodes of the stimulus matters pod including Strength-1 and Strength-2, the episode we hosted Mike Allen from AOD, and the most recent Deadlift episode - these would all be good places to learn a little more... however it's not "structured" learning.

@Jeff Wenglikowski of course - poke around and if you something interesting or have questions don’t hesitate to comment or post!
Program Design Review #1 is LIVE
First, thanks to @Jan Lenczuk for being willing to submit a real athlete’s program and open it up for discussion. It takes some guts to put your work out there. The intent behind these reviews is simply to give back to the coaching community. I’ve been coaching for a long time, and this is a way to share how I actually think through program design when I’m working with real constraints, not ideal scenarios. In this review, I walk through a full training week for Aga (Jan's client), a first-year RX athlete dealing with a shoulder issue, limited weekly training time, and long-term development goals. I start with athlete context and intent, then move into strength and hypertrophy decisions, gymnastics progressions, conditioning structure, and where I’d make adjustments or ask different questions. This is for coaches who want to improve how they think about programming, not just copy templates. If you have feedback on the format or ideas for making these more useful, let me know!

@Jan Lenczuk saw the second tab here - but I REALLY want to limit these to 30min for this format, so I got as far in that time frame as I could. I think big picture, definitely addressing the main pain points. As I said there are some minor things I might add to the program, nothing I would subtract. Having the 1RM’s for context would DEFINITELY make it easier for me to make objective recommendations and not be guessing - before I do the next I’m going to have the coaches send relevant PR info as well, I think that’s a necessary upgrade. Thanks again for volunteering!

@Luigi Giacomuzzi much appreciated!
Jan-15 Office Hours is live in the Client Vault.
This Office Hours went deep on carbohydrate timing. We talked a lot about how carb timing can matter as much as quantity, and how poor timing often shows up as bad sleep, inconsistent recovery, and late-night fueling chaos. We broke down why so many CrossFit athletes underfuel around training, then try to overcorrect at dinner, and then wonder why sleep quality and bodyweight feel unpredictable. We also covered intra-workout fueling as one of the most underused performance levers in the sport, how concentrating carbs pre/during/post training can clean up sleep without lowering total intake, and why scale weight often jumps when carbs finally increase (and why that’s usually glycogen + water, not fat). @Haley Ruth also put together a great content piece on this in the Nutrition section of RPL: https://www.skool.com/ruth-performance-lab-1681/intra-workout-fueling-guide?p=d8ccd320 If you’re training hard but still feel like recovery and fueling are harder than they should be, this one will change how you think about carbs and daily structure. All 1v1 clients can now watch it inside the Office Hours → Client Vault. For everyone else, I recommend just checking out Haley's post on intra-workout fueling to better understand the who / what / why / how !

Stim Matters: The Deadlift Deep Dive
This week @Ryne Sullivan and I dedicated the entire episode to deadlift inside of competitive CrossFit context. We covered everything from assessment --> programming for strength vs capacity --> technical issues --> and A TON more. In the episode I promised I'd provide a copy of my internal notes that I put together before the show, so I wanted to post those here for anyone who wanted them AND as a way to stimulate discussion. I'm really curious about how other coaches in the space approach "the deadlift problem" for competitors -- how frequently do you attack the movement? What are the principles or pillars you use for programming? Do you view the capacity vs absolute strength debate through a different framework? Episode link: CLICK HERE TO WATCH Notes below: ----------------------------------- 1. SEPARATE THE PROBLEM: STRENGTH VS CAPACITY ----------------------------------- Treat deadlift strength and deadlift capacity as two different adaptations. Strength - Neural output - Confidence in heavy positions Capacity - Repeatability of hinging under fatigue - Often shows up inside mixed-modal work Trying to solve both with the same tool is the mistake. Key takeaway: If you want to get someone stronger, you need to address the neural aspects of strength. If you want them to be able to repeat deadlift under fatigue, that's a 2nd order problem of metabolic demand + strength requirement. ----------------------------------- 2. DEADLIFT STRENGTH IS PRIMARILY A NEURAL PROBLEM ----------------------------------- Move away from high-volume deadlift strength work! What not to do: - High-rep tempo deadlifts (useless for building top-end strength in a healthy well trained athlete) - Large weekly deadlift volume “to get stronger” - Treating deadlift like a hypertrophy lift What to do: - Heavy singles, doubles, triples -80%+ of 1RM 5+ sets per week - Hand-release or full reset reps (no touch-and-go)

Coaches: Dealing with sick athletes?
I along with a number of my athletes are dealing with the classic winter respiratory infections. I’m curious how help your athletes navigate these?

@Caitlin Hutson I've actually had a very similar experience. Whenever I run a fever, all of my old injuries become incredibly sore. From my understanding of the physiology, the same inflammatory pathways that are active during injury, which stimulate the recovery process, are active during infection. So you're most likely not re-injured, just experiencing immune modulated inflammation as a result of the infection. Since its more than likely inflammatory mediated, I wouldn't think you'd need to work back through a full rehab process - but you may want to address by reducing loading and integrating some yielding isometrics in the first few sessions back. Check out my post on the Strain Recovery process, may give you some ideas too! https://www.skool.com/ruth-performance-lab-1681/my-strain-recovery-philosophy
