Stand with feet shoulder-width apart and place a barbell across your upper back. Brace your core and keep your chest up. Begin lowering your body by bending your knees and hips, pushing your hips back as if sitting into a chair. Descend until your thighs are parallel to the ground or slightly below while keeping your knees aligned with your toes. Push through your heels to stand back up, extending your hips and knees in a controlled motion. Keep your spine neutral and avoid letting your knees cave inward.
Squat for strength in the 3 to 6 rep range for 3 to 5 sets, resting 3 to 4 minutes so you can hit every rep with good depth. For muscle growth, sets of 8 to 12 with a slightly lighter bar build the quads and glutes without grinding recovery the way heavy triples do. Progress in small increments, 2.5 to 5 kg, and only add weight once every rep hits full depth with a flat back; chasing weight at the expense of depth just teaches a bad pattern. Squat first in a lower body session while your legs and central nervous system are fresh, ideally after a short warm-up ramp of empty bar and light singles.
How deep should I actually squat? Hips dropping below knee level, often called below parallel, is the standard for a full squat and is where the glutes and quads do the most work; stopping short of that is a partial rep even if it feels heavy.
Why do my knees hurt at the bottom? Usually the knees are caving inward or the heels are rising off the floor; both shift stress onto the knee joint instead of spreading it across the hips and ankles.
Is it bad if my knees go past my toes? No, some forward knee travel is normal and necessary for most people's proportions; the real red flag is the heels lifting or the knees collapsing inward.
