Spring tensioners are no strangers to fitness people, and the functions of tensioners are also very many. Many people use tensioners, and spring tensioners have many functions. What does the spring tensioner do? Let's get to know each other.

What is the function of the spring tensioner?

1, practicing deltoid muscle

Spring stretcher can exercise deltoid muscle well. The exercise method is to stand with two feet parallel, fix one end of the stretcher on the right foot, hold the other end of the spring with the right hand, and then lift the right arm forcibly. The direction of arm extension is forward until the whole arm is parallel to the ground, and then slowly put it down. After several operations, change your left arm for exercise.

Step 2 practice biceps brachii

It is necessary to bend the arm in the spring stretcher, and biceps brachii is a muscle with two muscle heads, whose main function is to bend the arm, so biceps brachii can be fully exercised in the spring stretcher.

Exercise: Stand with your feet parallel, step one end of the stretcher under your right foot, hold one end of the stretcher, keep your upper arm still, and then push your forearm upward and stretch it up and down repeatedly.

Step 3 practice triceps brachii

Triceps brachii is also used when bending the arm. The main exercise methods are: standing with your feet parallel, holding the back stretcher with your left hand on the lower left of your back, keeping one end of the spring stretcher motionless, and holding the other end with your right hand to stretch upward.

4. Practice flexor humeri.

The brachioradialis muscle is the main muscle in the upper forearm. It also plays a lot of roles in the arm flexion when using the spring tensioner, and it can also be strengthened by the lateral bending of the spring tensioner.

5, practice chest muscles

The use of spring tensioners to clamp the chest can make the pectoral muscles squeeze to the maximum extent, and stimulate the pectoral muscles by crossing arms, so that the pectoral muscles are constantly tense, thus achieving the effect of exercising the pectoral muscles.

Step 6 practice latissimus dorsi

The movement of spring stretcher can play a great role in exercising latissimus dorsi, and the contraction force of latissimus dorsi is needed when stretching spring stretcher. The main way to exercise latissimus dorsi is to bypass a post, like the iron post of a clothes hanger, or to fix two spring tensioners in one place, grab one end with both hands, stand with both feet parallel, and repeatedly stretch the spring tensioners in the body direction.

Step 7 practice leg muscles

You can also use spring tensioners to exercise calf muscles and front thigh muscles. For example, use two pairs of spring tensioners, step on the handle at one end of the tensioners with your feet, bend your elbows, and hold the handle at the other end with both hands (palms backward). The length of the tensioner is the distance from the hand to the foot when squatting. Then squat down, hold the handle close to the chest wall with both hands, and stand slowly with your knees straight until your body is upright. Slowly restore. When doing movements, the upper body should be upright and the waist can be slightly arched. This exercise method can exercise the front thigh muscles well.

Is it useful to exercise with a spring stretcher?

It is very useful to exercise with a spring tensioner. Although the spring stretcher is relatively simple, there are many ways to exercise. It can not only exercise latissimus dorsi and pectoral muscles, but also exercise the muscles of arms and thighs, which can play a better role.
