The Perfectly Sculpted Arse

The Science of Glute Hypertrophy

On this episode of the podcast/newsletter we discuss the science of glute hypertrophy. This is a topic of interest not only for aesthetic reasons, but also because the glute muscles have a large role to play functionally.

We begin by discussing the results of this study which compared hip thrusts to back squats for glute hypertrophy. They put participants through 9 weeks of training and used MRI to measure muscle growth in several different muscles. Here are the results:

Squat Group

Upper Glute Max: 12.8% increase

Middle Glute Max: 10.1% increase

Lower Glute Max: 19.2% increase

Quads: 12.6% increase

Hamstrings: 1.6% increase

Adductors: 10.3% increase

Glute Med/Min: .8% increase

Hip Thrust Group

Upper Glute Max: 13.7% increase

Middle Glute Max: 10.7% increase

Lower Glute Max: 21.5% increase

Quads: 6.8% increase

Hamstrings: .8% increase

Adductors: 4.1% increase

Glute Med/Min: 3.2% increase

Both groups had similar strength transfers to the deadlift and the horizontal wall push test.

We also discussed this study which concluded that squatting below 90 degrees seemed to result in larger glute hypertrophy than squatting to 90 degrees.

Finally, we broke down this study which gave a well rounded view of many different lifts and how well they recruit the glute musculature.
