Generally speaking, morning exercise is the best. As for what exercise, it depends entirely on one's sports hobbies. I recommend several: 1. Winter swimming.

Winter swimming is called vascular gymnastics and pays attention to step by step. jogging

12 minute jogging is popular all over the world. climb mountains

Can enhance heart and lung function. 4. Cycling

Can enhance heart and lung function. 5. Run in the morning.

Running can consume some fat and calories, so if you lose weight, I recommend jogging and long-distance running. Of course, pay attention to heatstroke prevention in summer and keep warm in winter.

Finally, I wish you health!
