Recently, running is getting slower and slower, and there are fewer push-ups. What happened?

Prove muscle fatigue after exercise. If you do at most 15 push-ups at a time, it will be fine to continue doing 15 after one week. It is recommended to massage by hand after each exercise 10~20 minutes. It will promote blood circulation and have a good effect on muscle formation. I suggest you replenish more energy and exercise continuously for 1~3 days, then you can rest for one day and continue the next day. I wish you a healthy road, running farther and farther ~ hope to adopt.
