I'm a bit confused on how to approach the warmup, in addition to the three reps attempt.
Based on links to the two most recent times we did the CFT, and based on two CF journal articles, I understand that the following is a good guideline for warming up:
Back squat:
5 reps @ 40%
3 reps @ 60%
1 rep @ 75%
1 rep @ 80%
1 rep @ 90%
Press and deadlift:
5 reps @ 40%
2 reps @ 70%
1 rep @ 80%
1 rep @ 90%
But Glassman talks about making your first attempt "one that you're certain you can do 3 reps of", your second "one you can do 1 rep without a doubt," and your third w/e based on how your previous ones went.
My question is that if I follow the percentages above for warming up, aren't I already going against the 3 rep approach?
And if you don't warm up like above, it seems might find yourself making a huge jump from the 2nd attempt (which you're certain you can do) to a potential new PR.
The way my brain works, it's difficult to put my focus into the WOD in front of me when the structure of how I should be approaching it is unclear. And I don't mean "what's the absolute best way", but rather "am I doing this wrong?"

Commented on: Understanding the Warburg Effect: The Metabolic Requirements of Cell Proliferation
I am writing to address issues regarding the role of the Warburg effect in cancer that was presented in the linked Vander Heiden et al paper. Much of the confusion regarding the Warburg effect has been clarified since the paper was first published in Science 10 years ago.
Vander Heiden et al correctly argue that cancer cells rely heavily on aerobic glycolysis (Warburg effect), not for reasons related to energy requirements, but rather to create the substrates for rapid cell proliferation. The authors also indicate that mitochondrial OxPhos must be normal in cancer cells if aerobic glycolysis is not the source of ATP synthesis. They go on to state “while the Warburg effect is widely recognized, there is no recognized explanation for why cancer cells behave this way”.
The recent paper by Chinopoulos and Seyfried has now clarified much of the confusion surrounding the Warburg effect (ASN Neuro, DOI: 10.1177/1759091418818261). Cancer cells continue to ferment lactic acid in the presence of oxygen because they have abnormalities in the number, structure, and function of their mitochondria. Whether ATP is generated through glycolysis depends largely on the pyruvate kinase (PK) isoform present in the tumor cells. ATP synthesis is greater in cells with the PKM1 isoform than in cells with the PKM2 isoform. Interestingly, many cancer cells express the PKM2 isoform thus making ATP synthesis through glycolysis limited. Chinopoulos and Seyfried reviewed extensive evidence showing that significant ATP synthesis could also be generated through mitochondrial substrate level phosphorylation (mSLP) in cancer cells that express both the PKM2 isoform and have abnormal mitochondria. In other words, ATP synthesis through mSLP can compensate for reduced ATP synthesis in tumor cells with abnormal mitochondria and the PKM2 isoform.
This phenomenon was described as the “Warburg Q-effect”, as glutamine (Q) becomes the major fermentable substrate through the glutaminolysis pathway (glutamine---glutamate---alpha-ketoglutarate---succinyl CoA---succinate). In addition to glucose, it is well known that glutamine is also a major fuel for cancer cells. Besides replenishing metabolites in the TCA cycle (anaplerosis), glutamine can also generate significant ATP through the succinyl CoA synthase reaction. Vander Heiden et al appeared unaware of the role of glutamine in generating energy through mSLP.
Both the Warburg effect and the Warburg Q-effect arise from compromised OxPhos. Hence, Recognition of mSLP as a second major compensatory energy mechanism for tumor cells with defective or insufficient OxPhos will have profound implications for managing most tumors including GBM.
The Warburg Q-effect is now recognized as the missing link in Otto Warburg’s central theory that cancer arises initially from environmental or genetic damage to a cell’s mitochondrial OxPhos. ATP synthesis through substrate level phosphorylation in the cytoplasm (glycolysis) or through substrate level phosphorylation in the mitochondria (mSLP) would gradually compensate for the reduced ATP synthesis from OxPhos. This process then leads to loss of growth control, genomic mutations, and abnormal proliferation, i.e., neoplasia.
Another misconception from the Vander Heiden et al paper was that aerobic glycolysis is required not only for cancer cell proliferation but also for proliferation of non-transformed cells grown in culture, thus giving the impression that aerobic glycolysis is a normal phenomenon of cell proliferation. This phenomenon does not occur in proliferating non-transformed cells grown in vivo. For example, a number of investigators showed that regenerating liver cells and normal colon cells use fatty acids and butyrate as fuel, respectively. Mike Kiebish et al showed that the cell culture growth environment suppressed Complex I activity and forced normal astrocytes to ferment through a Crabtree-linked effect (doi:10.1042/AN20090011). This cell culture effect would obscure differences in energy metabolism between normal cells and cancer cells. Indeed, Warburg and Burk cautioned against generalizations made on cellular energy metabolism based solely on studies from cell culture environments. As Chinopoulos and Seyfried described, respiratory impairment or inhibition, arising from either genetic or environmental causes, will force cells into a fermentation metabolism with consequent proliferation. The formation of lipid droplets, as is seen in many cancer cells, is further evidence of respiratory impairment. Lipids should be used as a respiratory fuel in cells with normal respiration capacity, and not stored as droplets in the cytoplasm. This new information has improved our understanding of the Warburg effect and the metabolic abnormalities that underlie cell proliferation in normal cells and in cancer cells.

I will likely have most of my athletes attempt to beat their numbers from 190207 as we are following a rest day. However, I will also touch base with each person, to see how they are holding up, after the combination of the heavy deadlifts, from Thursday, and the Open workout, from Friday. When having my athletes perform this workout, with the goal of getting a new personal best, I will advise a build up to approximately 95% of their previous max and attempt a new PR after that. For athletes the are not feeling optimal today, I may have them stay sub-maximal in loading, and keep mechanics sharp.
I will not alter the rep scheme for most of my athletes. However, some of my newer athletes might not be skilled or strong enough to reap the full benefit from heavy singles. For these athletes, I may have them do sets of 3 to 5 reps at sub-maximal loads. This can potentially be more beneficial and allow for more practice time with the movements.
During the workout, weight reductions may be needed for athletes that begin to display significant deviations from sound mechanics.
In special circumstances, where athletes lack the ability to achieve full range of motion with sound mechanics, I may potentially reduce the range of motion and work on heavy loads. Squatting to a target and deadlifting with the load elevated are both options for today. In between sets I can have them perform very light or unloaded movements striving to achieve full range of motion.
For this workout, I will typically give time allocations for each movement to keep the class cohesive and ensure that I finish the class on-time. Estimated time allocations will be: 17-20 minutes for the back squat, 10-12 minutes for the shoulder press, and 15 minutes for the deadlifts.

Globo Scale: As Rxed. Should not be a problem doing this in a normally equipped globo. Place mats down for the deadlift if the globo owner will yell at you for the noise from the deadlifts. Safety first: Use spotter arms and/or a spotter for the max squat if you can't bail it.
If on a cruise ship or somewhere with out a barbell, you can try doing a max set of each movement with the heaviest dumbbells available. Obviously you will have to do front squats with the dumbbell.

Champions Club Scaling Notes
Check the Compare-To link for notes on the last one.
STIMULUS:
I have long learned to trust the programming here and just go with the ones I don’t like. I don’t like max effort. I don’t like repeating workouts in short succession. And I don’t like coaching either of them because I don’t like making my members mad (most of the time). And here we have the CrossFit Total for the third(?) time since January. Just do it, I say. Lifting heavy is good for you. Doing 1 rep maxes make you focus a bit more (as a coach and athlete) on technique because you only have one rep to get it right. There are a million factors that go into setting a pr on anything, and sometimes they happen in the most random of settings — one of my track kids set a school record in the 400 after he ate 6 donuts not knowing he was about to run a 400. And sometimes a well-planned periodized program designed to peak when you need it to turns out a dud performance.
So lift heavy today, see what happens, and come out of it ready for tomorrow.
GROUP: / WARMUP: / KEY MATCHUP: / SCALING THIS WELL WILL CAUSE ME TO: / GENERAL FEAR LEVEL / GENERAL EMASCULATING LEVEL = all the same as last time. Except key matchup will be Cassius Winston vs. Zavier Simpson. Please Lord let Z make about 8 hook shots right in his mouth!

Cassius is the real deal.
Note exactly sure Sebastien. I know my personal bias comes into play - give me box jumps and kipping pull-ups any day over deadlifts and back squats. Also right now I'm the only coach, and I'm a control freak with form. Lifts only happen when a coach is watching. That makes it pretty challenging to manage a max effort session. Usually we'll have at least one more coach at a session and we'll split up the group so we can get a little more quality for each athlete. It's definitely a good challenge, though. So is Cindy. Doesn't mean I enjoy it while it's happening.
On a side note, we looked really good (for us, at least) on the Overhead squat max effort. I think those handstand descents are working!

I can’t speak for you or your memebers, but I know I wouldn’t like to having to be watched for every lift. And as a coach, I can only imagine my time could be better spent encouraging community bonding.
Something I did, is teach groups what to look for during each other’s lifts so I didn’t have to be there. Sometimes coming from a fellow member is better than coming from a coach. I could then easily focus on those who I knew I was a better help or needed the mental security of a coach. In the end people were able to talk to each other, high five, and laugh really loud during their rest. My gym seems to have a different experience during strength days and I hope I can help get you the same.

I feel where you're coming from. We've definitely had some people leave who wanted the reigns to be let off a bit more. I'm okay with that. Every affiliate has their own little ways of doing things that make them unique, and not everyone that walks in is the right fit.
The way I like to approach it is: the better your form is, the more freedom you get. And it's the coach (usually me) who gets the final say on what "good form" looks like.

We also have a pretty decent-sized representation from the track/running community. And even with the regular folks, the traditional couplet/triplet workouts are the most enjoyable.
But, like you said, it's probably on me to make the max effort sessions more lively.
