The squat is, perhaps, the single best exercise for leg strength and development. Squats are multi-joint exercises which significantly strengthens the muscles responsible for knee and hip extension: quadriceps, hamstrings, and glutes, as well as the smaller stabilizing muscles such as the torso musculature. It has benefits not just for your strength, but for balance, confidence, daily-life strength, cardiovascular capacity, and active flexibility.
Problem is, the squat is often taught incorrectly, and it's stigmatised as difficult and dangerous. People warn that it is bad for your knees and back (probably the worst myth of all), inappropriate for beginners, too hard to learn, blah blah. People who know nothing about a topic, especially a very technical one, that requires specific training, knowledge, and experience, are not due an opinion about that topic and are better served by being quiet when it is asked about or discussed.
Few people can do a perfect squat on the first try, or even the first several tries. Learning the basics of a squat is relatively simple, but perfecting the technique takes time and practice. Technique must always take precedence over weight. Don't be scared of adding weight once you get the hang of things, but never add weight that you can't handle. Don't cut the depth to be able to add more weight, either.
Using the squat has numerous practical applications in daily life: picking up a child, bags of groceries, manual labour in the garden etc. It's also great for anyone wanting to add more functionality into their lives because it mimics the movements we do each time we sit down or
stand up.
