Everyone is familiar with the barbell squat. I won't explain too much here, but there is one thing to pay attention to. When doing barbell squat, you need to master the angle of squat. When squatting, the knee is greater than 90 degrees to exercise the quadriceps femoris in the front thigh, and when squatting, the knee is less than 90 degrees to exercise the biceps femoris in the hip and back thigh.

The second exercise: sitting posture equipment leg flexion and extension

This action is to exercise with fixed equipment, mainly to exercise quadriceps femoris, and the route of the action has been set. Secondly, it belongs to individual joint action. Therefore, when practicing, you only need to master the weight suitable for your leg muscles.

The third exercise: leg lifting with sitting posture equipment

This movement is also exercised with fixed equipment, which is a bit like a barbell squat. Pay attention to the bending angle of legs and knees when practicing. Less than 90 degrees mainly exercises biceps femoris and gluteus maximus, and more than 90 degrees mainly exercises quadriceps femoris.

Exercise 4: Dumbbell Arrow Squat Lift

This action can be said to exercise the leg muscles and hip muscles. When practicing, the practitioner needs to pay attention to the angle of the arrow squat. When squatting, the knees of both feet should be kept at 90 degrees as far as possible, and the knees of the front feet should not exceed the toes.

The fifth exercise: sitting posture equipment leg bending

This action also uses fixed fitness equipment to exercise, mainly to exercise biceps femoris. The route and trajectory of the action have been set, which is also a single joint action. Therefore, practitioners don't have to care too much about whether their movements are standard or not. What's more important is to increase the weight of leg muscle exercises.
