2, the right male breast development, need surgery. Some boys exert their strength on the right upper limb, which leads to the development of the right pectoralis major muscle.
3. Bilateral chest asymmetry occurs. Generally speaking, this symptom may be due to congenital personal physical factors, and sometimes it may be rickets caused by calcium deficiency in infants. If there is scoliosis at ordinary times, it may also lead to this change. You can check the spinal X-ray first.
1, concentrated
Pay attention to the contraction activity of the pectoral muscle of the right (weak side) "shoulder" joint, and the range of joint activity is also larger than that of the left.
2. Pay attention to "elbow position"
The muscle training of the chest and back is driven by the shoulder joint, and the elbow is the farthest part of the upper arm. Only by controlling the elbow position can we effectively practice the contraction and extension of the lateral floor of the pectoral muscle.
Step 3 Practice "Dumbbells"
The dumbbell moves separately from left to right, which can obviously feel the force and control of the left and right hands and the left and right breasts, and is also the most effective training method that can really improve the strong and weak sides.
First, let's lie flat on the chair, arch our legs outward, hold two dumbbells in both hands and push them up until our arms are straight. In the process of pushing, stay for 2 seconds when your arms are at right angles to squeeze your chest better.
Do 3 movements in each group, and the number of times in each group is 15-20. After each group, adjust your breathing, stand up and do some warm-up exercises to relax our muscles, and then use fitness equipment to complete the follow-up actions.
