1. Skipping rope 2. Jogging 3. Swim for at least 30 minutes every day, because during these aerobic exercises, most people start to consume fat after 20-30 minutes, and fat used to mainly consume sugar in the body. I suggest you stick to 1 hour every day at first, and then you can gradually extend some time with the improvement of your physical fitness.
I wish you an early use of sports figure.
