- Shifting weight onto the toes.
- Descending too quickly without control.
- Using excessive weight at the expense of technique.
Special recommendations
- Wear stable, firm-soled footwear.
- Perform 2–4 warm-up sets before working sets.
- If ankle mobility is limited, a small heel elevation may be helpful.
- Prioritize proper technique before increasing load.
- Maintain a controlled tempo throughout the exercise.
When to use
- Building lower-body strength.
- Increasing muscle mass in the legs and glutes.
- Improving athletic performance.
- Enhancing functional fitness and movement capacity.
Consider modifications if
- Moderate lower-back discomfort worsens during the exercise.
- Moderate knee pain increases with loading or depth.

Exercise variations
Front Squat
The barbell is positioned on the front of the shoulders. Places greater emphasis on the quadriceps and requires a more upright torso position.
Pause Squat
Includes a 1–3 second pause at the bottom position. Improves control, stability and strength out of the hole.
Smith Machine Squat
Performed on a fixed bar path. Useful for beginners and for hypertrophy-focused training.
Goblet Squat
Performed with a dumbbell or kettlebell held in front of the chest. Excellent for learning squat mechanics and improving mobility.
Box Squat
Performed to a box or bench. Helps control squat depth and can increase emphasis on the posterior chain.
