Squats seem like a straightforward exercise, but unless you really pay attention to your technique, you could be doing it wrong. The Freeletics Coach will ask you to practice your technique every once in awhile. This is to avoid these mistakes: The most common mistake is not going down far enough. Your hips should always come below the knee. Many people also tend to lean their upper body too far forwards when lowering into the squat. Try to keep your upper body as upright as possible when going down. Once your technique is perfect and you’ve earned a star, it’s safe to try performing more repetitions. A perfect movement, that’s what we want.
