Introduction
Welcome to your next lesson in the Glutes and Hamstrings module. In our previous sessions, we've established a critical principle for hypertrophy: training a muscle through its full contractile range, particularly emphasizing the lengthened position, is a powerful driver of growth. We saw this with the hamstrings, where their biarticular nature demanded a two-pronged approach of hip hinges and leg curls.
Today, we will apply this same rigorous, anatomy-first logic to the gluteal muscles. The learning outcome for this lesson is to identify the lengthened and shortened positions of the gluteal muscles and select exercises that challenge the muscles across their full contractile range.
We will dissect the movements of the hip to define what "lengthened" and "shortened" mean for the glutes, and then map specific, common gym exercises to each of these positions. By the end of this lesson, you will have a systematic framework for selecting exercises to ensure complete, well-rounded gluteal development.
Defining Lengthened vs. Shortened Positions for the Glutes
To understand how to stretch or contract the glutes, we must first recall their primary functions. For this lesson, we will focus on the two main functional groups:
- Gluteus Maximus: The largest and most powerful of the three. Its primary job is hip extension (moving your thigh backward). It also contributes to external rotation and abduction.
- Gluteus Medius & Minimus: Located more on the side of the hip. Their primary job is hip abduction (moving your thigh out to the side). They are also critical pelvic stabilizers.
From these functions, we can deduce their lengthened and shortened positions:
-
For the Gluteus Maximus:
- Lengthened Position: Achieved through deep hip flexion (bringing your thigh towards your chest). This is the bottom of a deep squat or RDL.
- Shortened Position: Achieved through full hip extension, often with slight external rotation. This is the "lockout" at the top of a hip thrust.
-
For the Gluteus Medius & Minimus:
- Lengthened Position: Achieved through hip adduction (bringing your thigh across the midline of your body).
- Shortened Position: Achieved through hip abduction (moving your thigh away from the midline).
This concept of "lengthened overload" versus "shortened overload" is fundamental to intelligent exercise selection.
Category 1: Exercises for the Lengthened Position (Gluteus Maximus)
These exercises are defined by having the greatest challenge when the hip is in deep flexion. The NSCA refers to these as "vertical hip extension" exercises. They are excellent for inducing stretch-mediated hypertrophy.
Key movements in this category include:
- Squats (especially low-bar or with a forward torso lean)
- Lunges and Split Squats
- Romanian Deadlifts (RDLs) and Good Mornings
- Step-ups
The following video and article from E3 Rehab provide a fantastic overview of these movements and the specific techniques required to bias the glutes.
How To Grow Your Glutes (5 BEST Exercises + Gluteal Amnesia Myth Busting)
The video 'How To Grow Your Glutes' by E3 Rehab breaks down glute training into five practical categories. We will start with the two categories that focus on training the glutes in a lengthened position.
Watch the sections covering squats/lunges (02:33 - 06:36) and deadlift/hinge variations (06:36 - 07:52). Notice how the cues for all these exercises—deep hip flexion, forward trunk lean—are designed to maximize the stretch on the glute max at the bottom of the movement.
For a text-based review with helpful images, the companion article is also an excellent resource.
How To Grow Your Glutes - E3 Rehab
The article 'How To Grow Your Glutes' from E3 Rehab reinforces the concepts from the video.
Read the sections 'Squats, Lunges, Split Squats, and Step Ups' and 'Deadlift and Hinge Variations.' Pay attention to the visual cues in the images that demonstrate deep hip flexion.
The key insight is that to target the glutes in their lengthened position, the exercise must be most difficult when the hip is most flexed.
Category 2: Exercises for the Shortened Position (Gluteus Maximus)
These exercises are structured to have the greatest challenge when the hip is fully extended. The NSCA calls these "horizontal hip extension" exercises. They are ideal for targeting the glutes at their point of peak contraction where they have excellent leverage.
Key movements in this category include:
- Hip Thrusts
- Glute Bridges
- 45-Degree Hip Extensions
- Glute Kickbacks
Let's return to the E3 Rehab resources to see these exercises in action.

Now we'll look at exercises that challenge the glutes in their shortened position, where the muscle fibers are maximally contracted.
Watch the segment on bridges, hip thrusts, and 45-degree extensions (07:52 - 09:50). Note how the peak of the movement—full hip extension—is where the glutes must work the hardest against the load.

The article provides further detail on these shortened-position movements.
Read the section titled 'Bridges, Hip Thrusts, and 45 Degree Hip Extensions.' Focus on the technique descriptions that emphasize achieving full hip extension without lumbar hyperextension.
These exercises allow you to load the glutes heavily in a range of motion where lengthened-focused exercises have very little resistance (i.e., at the top of a squat).
Why a Complete Program Needs Both
You might wonder which category is "better." The answer, as is often the case in evidence-based training, is that a complete program requires both. By selecting exercises that challenge the glutes at both long and short muscle lengths, you ensure that you are stimulating the greatest possible number of muscle fibers across their full contractile range.
- Lengthened-position exercises are excellent for creating high amounts of mechanical tension and inducing stretch-mediated hypertrophy.
- Shortened-position exercises allow you to achieve a strong "peak contraction" and train the muscle where it has the best leverage, potentially stimulating fibers that are not as active in the stretched position.
The following video provides a more nuanced, first-principles breakdown of glute stretch and how different hinge movements can achieve it. Given your background, you will appreciate this deeper dive into the mechanics.
Breaking down Bret Contreras' Post - Prioritizing Glute Categories
In 'Breaking down Bret Contreras' Post', Kassem Hanson from N1 Education provides a high-level analysis of glute stretch and tension. This will deepen your understanding of why simply categorizing exercises isn't enough without understanding the underlying mechanics.
Watch from 15:31 to 20:58. Focus on the discussion of what it means to truly stretch the glutes. Hanson explains how achieving deep hip flexion is the primary goal and how various exercises, including RDLs and lunges, can accomplish this, sometimes even more effectively than a standard bilateral squat.
The consensus among top coaches and researchers is clear: combine these movement patterns for optimal results.
[PDF] Program Design Considerations for Optimal Strength & Hypertrophy of the Gluteal Muscles
This NSCA article provides a concise summary of the different exercise categories needed for complete glute development.
Read the section '1. EXERCISE SELECTION' and the summary table under 'PRACTICAL PROGRAM DESIGN FOR GLUTE DEVELOPMENT'. Note the clear distinction between Horizontal (shortened) and Vertical (lengthened) exercises, as well as the inclusion of Abduction movements.
A Quick Note on the Gluteus Medius & Minimus
Thus far, we've focused on the gluteus maximus. To challenge the glute medius and minimus across their full contractile range, you must include exercises that move from hip adduction (the stretch) into hip abduction (the contraction).
Examples include:
- Side-lying hip abduction (moving from a position where the leg is slightly in front of and across the body).
- Cable hip abductions (setting the cable anchor low and across your body to create a stretch at the start).
- Seated abduction machines (leaning forward can increase the range of motion and stretch on some fibers).
The E3 Rehab resources cover this "fifth category" of glute training well. You can review these sections for specific exercise ideas.
Conclusion
In this lesson, we have systematically identified the lengthened and shortened positions of the gluteal muscles and mapped specific exercises to each.
Key Takeaways:
- The gluteus maximus is lengthened in deep hip flexion and shortened in full hip extension.
- The gluteus medius/minimus are lengthened in hip adduction and shortened in hip abduction.
- Lengthened-position exercises (e.g., Squats, RDLs, Lunges) create a deep stretch and are most challenging at the bottom of the movement.
- Shortened-position exercises (e.g., Hip Thrusts, Bridges, Kickbacks) target the glutes at peak contraction and are most challenging at the top of the movement.
- For complete hypertrophy, a program must include exercises from both categories, as well as specific abduction work, to stimulate the gluteal muscles across their entire contractile range.
Preview of the Next Lesson
We have now established the anatomical basis for training both the hamstrings and the glutes. A key exercise that appeared in both lessons was the Romanian Deadlift (RDL), a classic hip hinge. In our next lesson, we will finalize our understanding of the posterior chain by formally differentiating between exercises that target the hamstrings at the hip (e.g., RDLs) versus at the knee (e.g., leg curls). This will solidify your ability to program for the entire back of the leg with precision.
