These two exercises can exercise the strength of lower limbs and waist and abdomen, which is what you said. The difference is that, firstly, weight-bearing squat is more obvious for muscle growth, especially for quadriceps femoris, while squatting posture pays more attention to respiratory regulation, especially abdominal breathing, and muscle growth is not obvious; Secondly, weight-bearing squat is not suitable for teenagers below 18, because it affects the growth and development of the spine, and the squat posture can be practiced from an early age; Third, the weight-bearing squat has great pressure on the knees and ankles, which is easy to cause sports injuries, and the squatting posture has a protective effect on the knees (note that the correct squatting posture requires that the knees should not exceed the toes); Fourthly, the weight-bearing squat is a fitness exercise in the West, which is based on the theory of human muscle anatomy, and it is "skin and flesh", that is, the place where it is not healthy, while the squat "horse stance just look" is the basic skill of traditional oriental martial arts, and it is more about training people's internal forces and "bones and muscles", which is also their essential difference. I hope my answer is helpful to you. Thank you.
