I bought a yoga disc, then a yoga mat, and I do yoga in front of the TV every day when I have nothing to do. The effect is very good. Really, I only work for half an hour at most every day, instead of getting fat, I lose weight.

Also, don't always sit or lie down every day. Stand when you can, especially don't sit or lie down for half an hour after a meal.

Run at home for half an hour every day.

In fact, the best way is not to eat after 6 pm. This will definitely not gain weight, but will lose weight faster.
