According to Daniel Pink, exercising in the afternoon or early evening can be more enjoyable because our body temperature is higher, making it feel less effortful. Additionally, people tend to enjoy afternoon exercise more and report better performance, hand-eye coordination, and lung function during this time. It's also better for avoiding injury due to the rise in body temperature. As for making exercise enjoyable, it's important to find an activity that you enjoy and that fits your personality and lifestyle. You can also try exercising with a friend or listening to music or a podcast to make the time go by faster. Finally, setting achievable goals and tracking your progress can help you stay motivated and make exercise more enjoyable.
