Depth and knee travel
Quads work hardest through a deep knee bend. Half squats and a hips back, chest down style shift load to glutes and back. Squat to parallel or lower and allow the knees to move forward so the quads stretch under load.
Why are my quads not growing?
Your quads likely lack direct volume and depth; add full range squats, leg press, and leg extensions to 12 to 18 sets weekly.
The quick answer
Quads usually lag from too little direct volume, cutting squat depth short, and letting glutes and lower back take over. Squat to at least parallel or below, add leg press and leg extensions, and build to 12 to 18 hard quad sets a week. Keep a fairly upright torso and let the knees travel forward over the toes to load the quads instead of the hips.
How to think about it
Add isolation
Leg extensions hit the quads with no help from other muscles and let you accumulate volume without frying your lower back. Two to four sets of high rep extensions after squats or press is a fast way to add quad specific work.
Volume and progression
Aim for roughly 12 to 18 hard quad sets per week split across two sessions, and add weight or reps over time. If you squat once a week for 3 sets, that is nowhere near enough stimulus to grow stubborn quads.
Do this
- Squat deeperFilm a set from the side and confirm your hip crease drops to at least knee level.
- Count quad setsTally squats, leg press, hack squats, and extensions; if it is under 10 a week, add more.
- Try heels elevatedA small plate under the heels or a slight elevation lets the knees travel forward and biases the quads.
- Progress the extensionsAdd a rep or a little weight on leg extensions each week and take the last set close to failure.
