Have a pair of strong legs, walk briskly and gracefully, and be steady and powerful. Here are three kinds of leg bodybuilding exercises: (1) Squat with bare hands, open your feet, raise your arms horizontally in front, hold your chest out, keep your head straight, look forward as if there are heavy objects on your head and arms, then kneel down slowly. When the squat is no longer low, stand up slowly and forcefully until your legs are completely straight and the muscles of your legs and arms are tightened to the maximum, stop for a while and repeat the reduction. During the whole exercise, keep your body in a natural vertical posture. Exhale when squatting, and inhale when standing up with your legs. This is a good exercise to develop quadriceps and hip muscles. (2) Shoulder Dumbbell Squat with both feet open, and lift the dumbbell to the shoulder with two hands. Dumbbells are high in front and low in back to keep balance. Then slowly bend your knees and squat down, stand up when you can't squat any lower, and do it 10 ~ 15 times after tightening your leg and hip muscles. (3) Squat your feet with the bell in both hands and stand on a solid low stool, holding a heavy dumbbell or kettle bell or two barbell pieces with proper weight in both hands. Then slowly bend your knees and squat down, stand up when you can't squat any lower, and let the calf muscles (soleus and gastrocnemius) tighten as much as possible, and then do it 15 ~ 16 times. Exhale every time you squat, and inhale when you stand up.
