After working for a while, I summed up a set of methods that can both keep fit and work. There are six rooms in my home. If you clean all the rooms at once, you will be very tired and can't achieve the effect of fitness. I usually clean two rooms after working for two hours, just like doing exercises between classes. In fact, you don't have to go to the gym for fitness, and the effect of cleaning the floor is not bad. Kneeling on the ground and pushing forward, the whole body can participate in sports. After wiping the sweat, I feel particularly comfortable looking at the clean floor. The weight was controlled in just three months, and after half a year, the "general's belly" became a "soldier's belly".
Cleaning the floor and exercising yourself can save a lot of money: hire hourly workers and go to the gym to buy medicine. It seems that exercise can be done anytime and anywhere, but it also needs wisdom.
