Introducing The Glute Lab: Part I – The Gang & The Strength Equipment

Hello fitness friends! I am super excited about today’s post. Some of you may remember a couple of months ago when I posted a blog mentioning that I was seeking to hire assistants. Well, I ended up hiring three guys! One of the benefits of working your ass off all the time is that you don’t have any time to spend money. Therefore, I was able to save up enough money to build a kick ass research and training facility (and hire amazing workers). We call our facility The Glute Lab


Over the course of the next year, we will be learning as much as possible about individual exercises and various training methods. In Part II of this series, we will discuss and showcase our technology and laboratory equipment. Needless to say, we will be bringing you some incredible information and reporting a ton of exciting data throughout the year.

Glute Gang

This is the gang. I freakin’ love our team. We’ve got some serious talent among us! Please follow the guys on social media!

Here’s a video of our facility:

Stay tuned for part II where we’ll show off our lab equipment and demonstrate how we collect data.


  • James says:

    Seems like you gathered quite an elite force of glute trainers there Brett ! Look forward to what you all have to offer. Will they be having their own podcast as well or will they be appearing on the one you already are on ? Would make for great roundtable discussions and opinions on glute training but also diets and industry movers and shakers.

  • Amanda says:

    Exciting!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! (you get the idea)

  • Kris says:

    Welcome glute gang, you seem awesome. I had been hoping for a woman in the gang but the credentials and accomplishments are impressive. Looking forward to your posts.

  • Sergio says:

    That’s a good gang man!

    And I want one if these t-shirts, the look nice.

  • Carisa says:

    How awesome!! I am excited to see all that is to come!

  • Patrick O'Flaherty says:

    Hey Bret,

    What equipment brand is the Hip Kicker? is this from Strength Inc. in Idaho?

    How does this movement pattern differ / compare to doing quadruped hip extension on all 4’s beneath a reverse hyper machine?

    • Bret says:

      Yep! I actually don’t like the straight weight option much and prefer using bands/weights. I don’t like it more than the reverse hyper method except that it’s more convenient, but the reverse hyper option was more effective for glutes IMO. Cheers, BC

      • Patrick O'Flaherty says:

        What about the original quadruped hip extension machine, the Leg Tech Butt Blaster, which is no longer made (appears to be replaced by the Big Fitness Butt Blaster LT4000) but can purchased used or refurbished?

  • JAIME says:


  • Congratulations! It looks like you have a strong team of Glute scientists on board. Let me know if you need test subjects 🙂

  • Patrick O'Flaherty says:


    On your video above, it appears that your butt is bumping the floor while hip thrusting?

    I know that being much taller than average at 6′ 4″ would contribute to this but also noticed that your feet weren’t directly under your knees in the top position, thus allowing yourself to descend even further. Wouldn’t this tilted shin angle generate more quad involvement and less glute activation?

  • John Buns says:

    Research powerhouse! Excited to learn about the knowledge this group generates!

  • JB morin says:

    Awesome Bret, such an achievement !!!
    nice T-shirts btw

  • emarnyc says:

    The group that will change butts around the world!

  • Marc says:

    Hi Bret good luck with your project
    It looks great. Keep well marc

  • Elva says:

    I wish I could train with y’all! Looking great!

  • Oreste Lombardi says:

    Nizhona! Wonderful!!
    Does this lab have some connection with your PhD dissertation? What is the subject of our dissertation if I can be that nosey to ask?
    I am pleased to know that you are going for a PhD at ASU. I will be expecting great information and discoveries from you. I read you with considerable interest. I try to get younger people to get serious about taking care of their bodies (I am 83).
