Pre-fatigue forces quads to engage earlier during squats.

Helps lifters stop shifting everything into dominant hips.

Great for quad bias when mechanics aren’t naturally favorable.

Light extensions first make squat tension hit immediately harder.

Works well for long-femur lifters struggling with quad drive.

Pre-fatigue reduces ego, increases actual targeted muscle activation.

Makes quads burn sooner, improving mind-muscle connection drastically.

Too much pre-fatigue just kills overall squat performance.

Moderate pre-burn helps balance quad and glute involvement well.

Works best with higher volume, not heavy singles.

Quad activation skyrockets when prefatigue sets are controlled.

Good hack when squats always feel purely glute dominant

Helps some, but technique fixes matter way more.

Great tool, just don’t overdo the early burnout.
