Not sure if this question is easily answered, but I've heard a different response from anyone I've ever asked.

Is there a need to 'solidify' your gains when going from a bulk to a cut?
IMO you or any other beginner shouldnt be cutting for the first few cycles. You can shape a mountain but you cant shape a pebble.

I am not aware of a trial that has specifically compared groups of subjects who immediately transition to intake deficits and those who do not, however I was actually discussing this very topic with Lyle a few months back and we both kind of agree that the answer may be "yes".

Yes, in the sense that hypertrophy is a complex process with numerous factors involved. Some of which happen more in the acute sense, but many others in a more chronic sense. So, if we immediately stop giving our body the fuel it requires to finish up these chronic process, then it would seem reasonable to speculate that some of these processes never complete, leading to "hypertrophy on the table" so to speak...
 
I'm on doctor's orders to avoid leg extensions... You want to talk about an exercise that'll fuck your knees up? There you go... And that's even with doing them correctly.

Squats on the other hand, completely different story. If you don't know how to perform them correctly, time to start learning. I've never seen form breakdown happen until too much weight gets added, and that's typical of a strength athlete. If we're talking about building mass, too much weight shouldn't be getting added.

But, we all have our preferences... :rolleyes:

Fuck leg extensions. Not only are they no good for the knees but I just don't believe they add any muscle. Now if you have muscle they can certainly add detail, separation, etc.

I will need knee replacements in both knees fairly soon but I continue to squat unless the pain is too great for me to maintain solid form. I do this for 2 reasons, one because I'm a powerlifter and squats are a competition lift. Even though I often compete push/pull only now due to the knee issues. The second reason is that all of my other lifts seem to improve when I'm squatting regularly.

Oh I know it is not a popular thing to say on bodybuilding boards because there will always be this you have to squat mentality shared by a subset of folks in the BB community.

But when we are talking about pure hypertrophy potential, I still feel the traditional barbell back squat is sub-optimal as compared to isolation movements (e.g. extensions/curls) which are sub-optimal when compared to unilateral movements (e.g. one legged variations).

Even if one does not agree with this, you then must factor in the inherent risk of the movement, which is very technical in nature. Even the slightest breakdown in form over time, increases the risk of injury (from nagging to severe). And quite frankly, I don't think everyone is built to squat, similar to how lever lengths may not lend well to someone being a great deadlifter either.
pretty similar to gh15 advice

you dont built big legs with big weights,,you build it with higher number of reps with moderate weight,,pay attention to the 110lb "fitness girl" in your gym,,when she is on the stepper and you are behind her,,take a look at her quad swip and leg development,,,i assure you she didnt achieve it with 6 plates 45lb each side of a barbell,,the fact you see bunch of whores and homos looking at you while you squat dont mean you need to put on the bar 6 plates,,you wont build NOTHING BUT YOUR EGO,,and even then it wont be for long

2. lift only as heavy as you can lift with good form! all the show off movements should be kept to either when your legs are the size of kamali legs and already been through the growing phase which was years ago for a professional bodybuilder,,or to a specific day of the month that you feel like showing off and not training the muscle for growth purpose. you dont go and put 6 plates each side of the bar when you are 200lb and the pro next to you is 270lb,,dont work this way,,,yes even if you are on drugs!! the fact you juice dont mean you need to fuck yourself up and not improve,,chose a day to do it,,once a month,,to satisfy your need to be the "best" in the gym

Your opinion and most recent literature consensus on sucralose and other artificial sweeteners, and its effect on insulin levels

Edit: I'd also love to hear other's opinions on this as well. I can start a new thread if this is the wrong place to hear. I don't see many studies on this out there

By and large, it is accepted that NNS (non-nutritional sweetners) do not impact acute or long-term glycemic load, even using extremely high doses of sucralose or aspartame.

Chest, thanks for posting... got around to reading these. I also found the following:

Hormonal responses to non-nutritive sweeteners in water and diet soda. - PubMed - NCBI

Fructose acute effects on glucose, insulin, and triglyceride after a solid meal compared with sucralose and sucrose in a randomized crossover study. - PubMed - NCBI

Reshaping the gut microbiota: Impact of low calorie sweeteners and the link to insulin resistance? - PubMed - NCBI

Short-term consumption of sucralose, a nonnutritive sweetener, is similar to water with regard to select markers of hunger signaling and short-term g... - PubMed - NCBI

First 2 seem to talk about changes in insulin levels and gut bacteria as it pertains to the consumption of artificial sweeteners in short and mainly long term. Second 2 I put in for fairness as I found them say sort of the opposite.

I think I'm understanding them correctly... if you don't mind glancing when you have time, is appreciate it
