Quad vs Glute Dominant Lunge

So it's leg day and you plan to do lunges, but should you keep your torso tall or bring your chest towards your thigh? There's no wrong answer! The real question is are you trying to increase the demand on your knee extensors (quad's), or your hip extensors (glute's)? The first demo in this video with a tall torso is a quad dominant lunge. My center-of-mass is back, right over my hips. My quads are having to do a lot more work because of this. It's all about biomechanics and the change in moment arm. Think of my thigh as the length of the moment arm.
Now compare that moment arm and my COM (center of mass) in the second lunge demo. We know trunk flexion drives hip flexion, and now my COM has shifted forward in between my hip and my knee. This change in position increases the moment arm at the hip, and increases the demand of the glutes.
In all reality a lunge targets a ton of muscles, including the quads and the glutes at the same time! But if it's leg day and you're trying to target certain muscles for growth, choose either style of the lunge and perform hypertrophy sets! Still skeptical? Try it out yourself and let us know what you think and feel!

Which one is which one 🗿😐

The leaning slightly forward is glute dominant.

[@danielltorres5895]

Neither is glute

There’s barely any difference
