Don't say you don't want to run if you want to lose weight! I used to weigh 156 kg, but now I weigh 130 kg, all of which are lost by running! I didn't want to run at first. Stick to it and it will be easy. Keep jogging for more than 40 minutes every day. If you don't want to go out, you can run at home! Also, if you want to gain weight, don't sit for 40 minutes after eating. Stand as long as you can! Sit down! Stick to running for a month and you will have obvious results!
