Physical fitness activities usually include three main parts, followed by warm-up, main exercise and relaxation.

1, preheating

The first part of physical fitness activities is warm-up. Warm-up is an essential preparation stage before any physical exercise. Its purpose is to gradually improve the heart rate and blood circulation, prepare for the body, reduce the risk of injury and improve the overall sports performance.

In the warm-up stage, you can do a series of mild aerobic exercises, such as brisk walking, jogging or skipping rope, to help speed up blood circulation and raise your body temperature. This can make muscles warmer and softer and reduce the possibility of muscle sprain or strain.

In addition, warm-up should also include some simple stretching and flexibility exercises, such as squats, push-ups and rotating movements. These exercises can help to lengthen muscle groups and joints, increase the flexibility and range of motion of the body, and prevent muscle pain and injury.

2. Main exercises

The main exercise is the most challenging and important part of physical fitness activities. This is the stage of improving physical fitness and health by choosing specific sports, exercises or activities. The main sports can be different according to personal preferences and goals.

For example, aerobic exercise (such as running, swimming and cycling), strength training (such as weight lifting, push-ups, pull-ups) or flexibility exercises (such as yoga and pilates). The main goal of exercise is to improve cardiopulmonary function, enhance muscle strength and endurance, improve flexibility and promote overall health.

Step 3 relax

Relaxation is the last important link in physical fitness activities. After the main exercise, proper relaxation can help the body return to normal state and reduce the degree of muscle soreness and fatigue. Relaxation activities include slow and gradual aerobic exercise, such as walking or relaxing swimming, to help reduce heart rate and breathing frequency.

In addition, stretching and deep breathing exercises can also promote muscle relaxation and stretching. The goal of relaxation stage is to balance and restore physical condition and enhance physical and mental health.
