To perform a narrow squat, start by standing with your feet slightly wider than shoulder-width apart. Then, lower your body by bending your knees and pushing your hips back, as if you were sitting in a chair. Keep your chest up and your back straight throughout the movement. As you lower your body, make sure to keep your knees in line with your toes and your feet flat on the ground. Once you reach the bottom of the squat, pause for a moment and then drive through your heels to return to the starting position.

The frequency of narrow squats will depend on your fitness goals and current level of fitness. Generally speaking, if you are looking to improve your overall strength and fitness, you should aim to do narrow squats two to three times per week. If you are looking to increase the intensity of your workouts, you may want to do narrow squats four to five times per week.

A narrow squat is a type of squat in which the feet are placed close together, while a regular squat is performed with the feet placed shoulder-width apart. Narrow squats are often used to target the inner thighs and glutes, while regular squats are used to target the quads, hamstrings, and glutes.
