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?
Coaching Conversations EP4 - Zone 2 is Over rated
This week Kyle and I started off our conversation talking about the parallels between what Grant House had to say on last weeks Office Hours and what my general disposition is towards run training in the CrossFit space. From there we touch a number of different topics including - Some of the biggest adjustments we have made to our coaching processes - How we use med ball throws and jumps/plyos to develop gymnastics - Why writing a stand alone conditioning session without context isn't good enough Full episode can be found here: https://open.spotify.com/episode/6KuXNkFTkDOc0VPBmiLJ4v?si=E7HPvwWTRjWzWVVBFvRnZA Please ask questions, challenge ideas or post thoughts that you had while listening to this. We all learn through discourse

@Kyle Ruth what is the intention behind the zone 2 piece? Are we looking for minimum effective dose of zone 2, something to finish or precede a session? Something else?

@Kyle Ruth so I would structure it something along these lines for zone 2 replacement 15 minute warmup: 1k EB, 200m jog at true zone 2 pace (2 min/mile slower than 5k pace) --- 6 x 200m run at LT2 effort (45 minute-60 minute), walk 1:1 4-6 minute EB at R1 effort x 4 sets Then if they needed more tissue tolerance than that, I would have them loaded walk after. All in this session accumulates about 6k worth of running. Heart rate will likely never go above zone 2 but we keep the quality of contraction much higher and more readily applicable to the sport
10sec peak power
Anyone up for capturing 3 attempts to establish a 10sec peak power (wattage) on the C2 bike? I messed with it today, damper 10 and got 1113, 1155, 1355 (200# on the dot this morning) Interested in male / female scores - even better if you include BW so I can get a watts/kg read. I’ll report all the data back here.

@Charles Chung I think that peak power time orientation is going to be related to the nature of the human. People who are "twitchy" will trend towards earlier and people who are a bit more enduring will trend late. That said, on a fly wheel bike, hardly anyone can go sooner than 5 or 6 seconds because of how the machine reads. Something I would be curious is if peak wattage changes with a spinning start... so something like 10 seconds at 50-60 rpm then attack @Kyle Ruth
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?

One of my favorite rules is if the congestion/pressure is above the neck, you can train with modified intensity. If its in the chest, you rest. Personally, I have a few things that I find help with prevention 1. Get in the sauna more frequently 2. Focus on making sure that I am nasal breathing as much as possible when away from exercise 3. Increase sleep by 15-20 minutes per night on average
Running Shoe Resource
https://www.doctorsofrunning.com/ In my opinion, this is the best way to find a shoe that works for you. Now is the time of year where they do the "best of" series, so if you are in the market, I would recommend starting here. If you know you like a certain type of shoe, they have a similar shoe note on each profile. From there, I would strongly recommend going to a running store that has the shoe to try it on or making sure that you have a good return policy with online orders. I have had several shoes where everything indicated I "should" like it and absolutely hated the shoe. If you dive into this a little bit, you will start to understand why I don't like to give my opinion on "good" shoes for people to run in
