Causes of stretching abdominal muscles
1, stretching can improve blood circulation.
When doing strength training in fitness, muscles will be congested, and full stretching can effectively circulate blood.
2. Stretching can discharge lactic acid accumulation
After fitness, there will be some lactic acid accumulation in muscles, especially those who do not exercise for a long time, and their muscle ability will decline. Proper stretching after training can accelerate the excretion of lactic acid in the body.
3. Stretching can improve the strain point of muscles.
People who train regularly are not prone to muscle fatigue, especially when doing strength training. People who train regularly can completely exhaust the target muscles and stimulate them better.
4. Stretching can reduce muscle adhesion.
Muscle adhesion will occur after fitness, especially for people who only do strength training during fitness. If they don't stretch, their muscle shape won't look good.
5. Stretching can increase the flexibility of the body.
Fitness stretching can open ligaments and make the body softer. Fitness should not only have masculine beauty, but also make your body more flexible.
6. Stretching can relax the muscle fascia.
Many bodybuilders will use special methods to relax the muscle fascia and increase the speed of muscle growth.
7. Stretching can improve muscle lines.
Stretching after fitness can play a role in shaping and make your muscle lines more perfect.
8. Stretching can improve muscle function.
Stretching after fitness can increase the range of muscle activity and enhance the coordination and adaptability of the body.
9. Stretching can avoid sports injuries.
Fully warm up before the start of fitness, and fully stretch after fitness to prepare for the next training.
Matters needing attention in stretching abdominal muscles
1, select the appropriate weight.
When we stretch passively, we should gradually increase our strength. It is suggested that the general weight should not exceed 50% of the stretching muscle strength. And you have to follow a principle, that is, slow movements use a relatively large load, and fast movements use a relatively small load.
2. Stretching duration
For different ages and different joints, the repetition times and time of stretching are different. Generally speaking, the maximum stretching state lasts 10-20 seconds for each exercise.
Step 3: intermittent stretching
Keep your muscles fully recovered and practice the next group. The rest time of trunk is longer than that of ankle joint. During the intermission, you can arrange some muscle relaxation or some massage exercises.
4, the degree of stretching stimulation
Because the human body has certain flexibility, in our stretching, we need to exceed the normal length or range of motion of the stretching part. But be careful not to force yourself to stretch to the maximum, otherwise it may cause joint deformation, affect joint stability and body shape, and also affect the explosive force of physical strength.
