Adam Schafer
All right, all of you that want to build a round, amazing. But we have a glue building masterclass with one of our top trainers, Corinne, live. We're going to talk about it right now. Let's get into it.
Corinne
It's going to be live too, just so you know, so you'll be able to engage with her as she's going through the whole thing.
Adam Schafer
So Corinne is. She's a bikini competitor. She's a trainer. She's one of our top trainers and she's. This is a live. This will be streamed live. So you can go sign up for it. It's mindpumpmasterclass.com and she's gonna go through the two best exercises to build your glutes, the hip thrust and the squat. But it's not just the hip thrust and the squat. It's really breaking them down and making them as effective as possible. Because I think a lot of times people will do certain exercises, especially the squat, but this can happen with the hip thrust as well where they're not getting the res quite the results that they thought they would get or it doesn't feel right. I've actually heard people say their low back gets fatigued on a hip thrust or something doesn't feel right on a squat. And she's gonna like teach you. Like here's how you do these to maximize glute gain.
Justin Andrews
There's a lot more nuances to these lifts than I think people realize. And just technique wise and just, you know how to hold your body in certain positions and maximize that effort.
Adam Schafer
That's right.
Justin Andrews
Direct it. So she's going to break all that down.
Corinne
Well, I'll tell you guys how we got here. So it was what, last month I think her and I did the webinar for hip thrust and squat and that was a like a pre recorded thing that her and I did. And since then, the amount of questions that she's been fielding both in the muscle mommy group and the people that joined that webinar have been all these things that she's going to cover. So, like, we answered so many questions related to that. She was like, okay, let's do another one. And I feel like I've got a really good idea of, like, what most people are asking. And so we can go even deeper, dive on some of the things that we taught. So, you know, if you enjoyed that first one, you'll still get a ton of value from this because that's like, in addition to this, it was like, these are the questions that people had.
Adam Schafer
Well, so. So of course, course she's going to go over technique and form. So of course. And again, it's live. So she'll be demonstrating the exercises and talking about them, but she's going to break it down to the important components because you can watch form on a video or even in front of yourself, but you might not have, like, proper activation is a good example. And I think the barbell squat's a good exercise to talk about this with because it's a little bit more complex than the hip thrust. Although the hip thrusts don't sleep on it, there's some complexity there as well. But like with a barbell squat, you know, when you're. The muscles that are. That are creating the movement are primarily the quadriceps, the hamstrings, and the glutes. Now, they're not the only muscles that are active. You're actually getting some calf and soleus from the ankle flexion and extension from the bottom of the top. You're also getting lumbar spine, so you're getting all that lumbo pelvic hip area, so the lumbar spine, the core. You're getting thoracic activation from where you hold the bar and how your posture is. So that's all happening. But when you're doing a barbell squat, there are ways to do a barbell squat where more of it's going to go to the quads, for example, and that's perfectly fine if that's what you're looking to develop. But if you're trying to do a barbell squat and really trying to make it work and grow and shape your glutes, there are ways you could teach your body to activate better so that that exercise becomes much more effective. Without that, oftentimes, and you see this with a lot of people, they do the squats, they get stronger at the squats, they see the quad development, they don't quite see the glute development.
Corinne
I find it's probably the most common challenge. It's interesting because we obviously been doing this for a really long time. Um, you know, 20 years ago, I felt like just getting my female clients to squat was revolutionary. Like, just very few female clients of mine barbell back squat before 20 years ago. Yeah.
Adam Schafer
Yeah.
Corinne
Before I trained them, where it's actually really common now. It's very uncommon. I would say that you meet a. A female that is working out in the gym trying to build her butt and hasn't already tried squats. I mean, it's pretty well known now that squats are one of the best exercises if you want to build the butt. But what has become extremely common is a lot of people that do squat but can't get the development that everyone sold them on. And it could be for a series of things, but I'd say calories and activation are one and two, and you could interchange those. I think they're probably 50, 50 on what I hear back.
Adam Schafer
Not eating enough to support growth.
Corinne
Yep.
Adam Schafer
But the other one's activation.
Corinne
Yeah.
Adam Schafer
Which in my opinion, the activation one can be the most frustrating because you're doing the work. You're doing the work. Yeah. And it's.
Corinne
You just don't see it.
Justin Andrews
And a lot of times, too, you're. You're not feeling it as well. And so this is something to address, you know, the recruitment process of activating those glutes, getting them involved, really making it a little more posteriorly driven.
Adam Schafer
That's right.
Corinne
It's also. It's a little bit more mysterious or difficult to solve than, say, the calorie problem.
Adam Schafer
That's right.
Corinne
The calorie problem's pretty simple. It's like, eat more calories or hit your protein intake. Right. It's very clear and cut. You can measure it. You can go like, oh, I don't do this. Problem solved. Where, you know, tell somebody who squats and they go, I don't feel at my butt. And you go like, well, think about it.
Adam Schafer
You know.
Corinne
You know, you're like, I'm thinking about it. And so, you know that that's where this gets a little challenging. This is where the coaching and the training and I think, you know, having somebody like a Karen who's got, like, so much experience, huge difference. Being able to cue somebody the right way to be able to feel it. And then you unlock that. Right. And then there's like, oh, okay, now I feel it. Now I get it. Now how do I translate that over into the squat so that I'm getting this better?
Adam Schafer
This is Such a big deal. And again, it's frustrating because you may be squatting, you may be doing all the right things. The squat doesn't hurt you in a bad way. So, like, it's like, I have an injury, I feel okay doing it. I've added 15 pounds or 20 pounds to my squat, and what I notice is my quads are looking great. My butt looks no different whatsoever. What's going on? Is this incredible exercise for the glutes not what people say it is? And it's like, no, it is. It's phenomenal. This is where good coaching makes a big difference. A coach can change your technique and activation in ways that dramatically improve the effect of the exercise. This is what strength coaches do so well with strength sports. I mean, you know, this is not the same topic, but you could be someone who deadlifts and bench presses all the time. Then you hire a powerlifting coach. And in that session, I've actually seen this before. In that same session, somebody could add 10 pounds to their lift. It's not like they got 10 pounds stronger. But the powerlifting coach knows exactly how to cue the person.
Justin Andrews
Yeah, this unlocked more potential.
Adam Schafer
Right. And so that's what activation's all about. And she's going to cover that with both the hip thrust and the squat. She's also going to uncover ways to improve mobility. This is a very common issue with these exercises. Again, in particular with the barbell squat. If you have ankle mobility that is lacking deep barbell squats, because the deep part is where you'll get the most glute activated, it's impossible. It's just not going to happen because your ankle mobility is not going to have it. Or if you have hip mobility issues, you now you're going to start to feel hip issues most commonly in the front of the hip. I think people trip out over that where they'll do squats or whatever, and it's like where the hip flexor is. It feels like something's catching. And there are mobility movements you can do that make a tremendous difference to how you.
Justin Andrews
Those little compensations, they really get in the way and they impede on that communication channel and to the further point of activation. It's like a lot of times, you know, some people can't actually get to the point where they really feel and concentrate and can activate and recruit. If there's limitations along the way down, which, you know, mobility helps to really open that up and unlock it for them.
Corinne
Well, it, it, it impedes on technique, technique impedes on activation, activation Impedes on results.
Adam Schafer
Yeah. Yep.
Corinne
And so it's all connected. It's all connected. And, and this is the, the, the, the next one I feel like. So I said what 1 and 2 I feel like are most common is that the next one would be mobility issues that either limit somebody's range of motion or change their technique to where. An example, and an example that is I. I have poor ankle mobility, but I hear that people say deep squats hit your glutes. And so the client thinks that they're going deeper, but really all they're really doing is folding over further. Yeah, Right. So they feel like, I gotta get, get, get down lower. And in order to do that, they can't go any lower because they lack the ankle mobility. So their chest comes forward more than the bar is now traveling closer over to their knees versus up, up, further back on their thighs. And now they feel all quad dominant because they're leaning forward when they're doing that, and they don't even realize that.
Adam Schafer
Or you're creating the potential for injury because, you know, as you squat down and we'll stick on the topic of ankle mobility, although that's not the only mobility that she's going to talk about. But with ankle mobility, sometimes people will force themselves to go lower. And because the ankle mobility is lacking, there's this outward torsion where the feet want to turn out and twist. But because you're on the ground with weight, it actually creates torsion and twist and the knee joint starts to support it. And now you're doing your squats, you feel okay, but over time, like, that hurts my knees. Well, why are my knees sore?
Justin Andrews
Yeah, even just like on staying on mobility, like not having proper, like, shoulder mobility to even retract back is far enough. You know, think about having rounded shoulders a bit and then putting weight on top and that propensity to now kind of push you forward just from that.
Adam Schafer
Thoracic mobility issues is one of the number one reasons why a person can't have a bare bar on their back. Why it hurts. So if you're listening right now and you've tried barbell squatting with a hard bar and you put it on your back, you're like, that hurts my neck. That hurts my spine. And you think it's because you need to have pounds of muscle on your back, that's not what's happening. What's happening is you have poor thoracic activation, mobility and placement because that bar will hurt nobody if you place it properly. Even if you're petite. Or whatever, it doesn't hurt. And bar pads are terrible. A bar pad, although it makes it comfortable, changes the movement because it raises the center of gravity and actually changes the exercise. And a good coach knows this.
Corinne
And it also crutches the main issue. You just said, too, like a lot of people that don't have that thoracic mobility. That's the only reason why. I mean, you have obviously examples of people that have shoulder issues or surgery they just had, but for the most part, they lack the thoracic mobility because they lack the thoracic mobility. Then they put the bar pad on because it hurts, because it's resting on their neck. And now it's like your. Your technique is already from the. From the jump is already off. And then to think that you're going to have this proper recruitment pattern that lights the glutes up like you want is very, very unlikely.
Adam Schafer
That's right. I mean, you know, if. If an exercise was worth 100 points in terms of glute development, lacking in areas like mobility activation, it's gonna take that 100 points and it could bring it down as low as 50 or in some cases as low as 10. An exercise that is supposed to be phenomenal for an area now becomes terrible for that area. Because of the things that we just
Corinne
talked about, you know, talking about activation too. Something else that is common that we didn't touch on is, you know, the ability to keep your knees from collapsing in. I'd say that's probably another common one. And so learning to activate the glute mead, which is responsible for keeping the knees from folding in like that. And, and it's just, it's natural. Right. If you tell a client who's never squat before, just squat down, you almost always see somewhat, if not an exaggerated, like, collapsing of the knees inward. And that's a part of the glute that's not firing properly. The glute mead is one of the. One of the parts of the glutes that is responsible for that. And so learning to activate that and keep that from happening as you drop down into the squat makes a huge difference, not only on the mechanics, but then also also on the development and the shape of your butt. And so understanding how to activate that going into the squat matter. So all these little nuances and, and almost always when I get somebody, it's never just one thing. It's a couple of these things.
Adam Schafer
Each one connects.
Corinne
Yeah. That are. That are exacerbating the other ones that result in this person who just cannot Feel it in their butt.
Adam Schafer
And.
Corinne
And once we solve that problem, it completely changes everything. And then it's, it's game over. Then they're building totally.
Adam Schafer
She's also going to talk about how to access a greater range of motion. Now, part of this is activation, mobility, what we just talked about. But part of this. And now I'm going to point to the hip thrust. The hip thrust is a phenomenal exercise, but depending on the size of the plates, the bench that you're on, and your form and technique, you can have a short range of motion or you can have a long range of motion. And this didn't really occur to me because I'm six foot tall guy, I can use a regular bench, the 45 pound. Like if you're a petite girl in particular, your range of motion is short. Getting on the bench can be kind of weird. And how do you do that? What do I do? I put my feet on plates to increase the range of motion. She's going to talk about this. A greater range here. Hip thrust is phenomenal at activating the glutes. It's easier to activate the glutes with a hip thrust than it is with a barbell squat. Doesn't make it better, it's just easier.
Corinne
Where it lacks is the range of
Adam Schafer
motion, range of motion. Now, there are ways to access greater ranges of motion with the hip thrust to dramatically improve its effectiveness. And this is again, this is where coaching comes into play.
Justin Andrews
Yeah, and one, that I wasn't really gonna bring up. But two, another one on the list is like, you know, really bracing properly and like activating your core. But like, that's gonna help with the greater range of motion so you're more stabilized so you can actually have strength in that range.
Adam Schafer
That's right. So like the PE tilt that you're in when doing a hip thrust makes all the difference in the world. It can make a hip thrust fatigue your glutes, or you can suddenly feel an exercise that shouldn't fatigue your low back all of a sudden. Become a low back.
Corinne
Oh, yeah.
Adam Schafer
Low back and hip flexor.
Corinne
That's right. It ends up being low back and hip flexor. If you don't know how to activate that properly.
Adam Schafer
She's also going to cover rep ranges. Low reps, moderate reps, high reps, what each of them are good for, why you'd want to do either one, what the strengths and weaknesses are of each of those rep ranges. She's going to talk about frequency. How often should you do these exercises? And if you do them more than once a week. Do you mix up the rep ranges? What about the sets? So she's going to actually cover programming, which I think is the right dose. That's right. What's the right dose and how is that going to affect my progress with my glucans? And then finally she's going to talk a little bit about diet because I think that makes it complete. I don't think you can talk about building an area of your body without making sure that you know, at least minimally cover the effect of diet. Because like you said in the beginning, Adam, you could do all the right things. But. And this is more common for women than men, if you're not feeding yourself properly. What does that look like, by the way? But if you're not feeding yourself properly, nothing's going to happen. Nothing's going to happen.
Corinne
Well, the last two are paramount to the success because if you listen this far and you're like, oh no, I've got good this. You check all the boxes like you have been taught how to do all the movements correctly, you understand how to activate it, you got good range of motion, you've worked on mobility, yet you still can't build your butt. This is it.
Adam Schafer
This is probably.
Corinne
It's either one, the programming or the nutrition or more often than not both. Some sort of combination to it where somebody is over training and underfed or like the. The frequency at which they're doing is either not enough or too much because this is not one of those things. And this is the approach that I think where we go wrong. And this is not just someone who's trying to build a butt. I as just people in general, more isn't always better. It's the right dose. It's the what is the right amount of training volume for me to send a signal to my butt to grow. Feeding it the proper amount of nutrition, also giving it the proper amount of recovery to do what it needs to do. Because what ends up happening a lot of times when someone is highly motivated to build something, whether it be a chest or a butt or shoulders or any other muscle, is they think just more of it, harder they do it, the more results they'll get. And then you get stuck in that thing that Sal likes to talk about, the recovery trap, where you're just constantly breaking down and you're never allowing the body to build and recover. And so this last piece, that frequency programming piece paired with the right nutrition is the last unlock to all the other stuff.
Adam Schafer
Yeah. And just so I can encourage people, the glutes are not a hard muscle to grow. They're very responsive, very responsive muscle. In other words, if you're tuning in and you're like, it's just not happening. I want my butt to respond. I want to get that round butt. I want to be able to develop it. It's just not happening. It is a problem with a clear solution. This is not one of those parts of the body where you find notoriously difficult for some people to develop, like the calves. You'll hear about that sometimes with some people, glutes grow. If you do it right, you feed yourself, they'll grow. It happens 100% of the time. So if you're struggling, go to mindpumpmasterclass.com Sign up for this live masterclass where Corinne, again, one of our top trainers, is going to walk you through all the important components to developing incredible glutes. And chances are, if you're struggling, you'll get the right answer, apply it and then watch what happens. Look, you can find us also on Instagram. We'll see you. It's at Mind Pump Media.
