Push-ups and sit-ups are certainly helpful for running.

When running, the requirements for cardiopulmonary function and balance are very high.

Push-ups can increase chest circumference, enlarge chest, exercise the endurance of upper abdominal muscles, help to adjust breathing and increase vital capacity.

Sit-ups can exercise the upper and middle parts of abdominal muscles, and the lower part is not as obvious as the upper part. Both sit-ups and push-ups can exercise your abdominal muscles, which plays a great role in stabilizing your breathing and heartbeat and maintaining your balance during running.

In this way, your body can maintain a stable balance for a long time, whether it is running for a long time or erupting for a short time.

Junior high school boys should be around 13~ 15 years old, which is not suitable for high-intensity training. Sit-ups 15, 4 groups in the morning and 4 groups in the afternoon. Do push-ups every day, morning 10 group, afternoon 4 group.

Push-ups help swing your arms.

All of the above are auxiliary training for running, or a better foundation, which requires continuous running practice to improve greatly. After making so many calls, please reply at least one, ok!

Finally, I hope you can improve greatly.
