The first type: parallel bars arm flexion and extension:
As a warm-up action for the chest, focus on building the lower chest.
Action points:
Clamp your elbows, lean forward, chin inward, and hold your chest slightly. Keep this posture at the beginning and end, and don't put the bottom of the movement too low, so as not to put too much pressure on your shoulder joint.
The second type: barbell bench press:
Create the entire bust. Different grip distances have different emphasis on stimulation. The pectoralis major in the middle is slightly narrower than the shoulder, the whole pectoralis major is shoulder width, and the lateral pectoralis major is slightly wider than the shoulder. If it is wider, it will focus on exercising the posterior deltoid.
Type 3: Tilt the dumbbell upward to push:
Exercise the upper pectoralis major. The advantage of dumbbell over barbell is that there is no bar limit, which can fully stretch pectoralis major. Be careful not to put it down too low, so as not to strain pectoralis major. This exercise is done in the front, because free weight consumes a lot of energy. The angle of the inclined plate is controlled between 30 and 45 degrees. If the angle is too large, the pressure on the toe of deltoid muscle will be greater, which will affect the stress on the pectoral muscle.
The fourth type: downward inclined dumbbell bench press:
Exercise the pectoralis major. It is recommended that dumbbells or barbells be placed on both sides of the bottom rib, not in the middle of pectoralis major, so as to avoid pressure on the shoulder joint.
The fifth kind: butterfly birds:
Exercise the separation degree of thoracic groove. Adjust the height of the seat so that the handle is at the same height as your shoulders and keep your arms slightly bent. Be careful not to spread your arms too much (just open them to the back plane) to avoid damaging your shoulder joint. Not too heavy. Pause for 3 seconds during adduction and fully squeeze pectoralis major.
Sixth: cross-clip chest of the puller:
Exercise lower pectoralis major and middle pectoralis major. This action has obvious congestion effect. Use light weight many times, keep your elbows slightly bent, bow your head and hold your chest out, and squeeze your chest muscles as much as possible at the top of your movements.
Seventh: flat dumbbell bird:
As the end of chest muscle training. Use a light weight to keep the elbow slightly bent at a fixed angle, just put it on the back plate. It's like holding a big tree when you lift it, instead of pushing it straight up and down, feeling the stretching and contraction of your chest muscles.
Be careful not to strain your muscles during exercise.
