Squats are the bread-and-butter exercise of lower body strength programs, helping to strengthen and grow muscle in your quads, glutes, hamstrings, hip flexors, lower back and core muscles. But they’re easy to get wrong, and you might not even realize you’re making any mistakes.
Pain in your lower back or joints could indicate that your form might be off, as is “butt winking,” common in beginners or people with limited mobility, causing rounding in the lumbar spine.
