In fact, concentration is a very valuable quality. Shortly after I started running, I occasionally wore headphones to listen to songs and ran to the beach. Running makes me feel very empty, and I also think about some problems in the running process. For example, running is boring. Should we have some fun when running? You can recite words while running, or read some literature. In fact, running on the treadmill itself is a relatively monotonous and boring thing. Memorizing words should be monotonous for most of us. When two monotonous things meet, I don't think you can last long. I think it will be more efficient to separate running time from other study and work time and recite words after running and taking a shower.
