Exercise in the morning can use the following contents: running 1000 meters, pulling ligaments (all joints can be used, pulling calves and hips when sitting too much), and then doing your favorite exercise.

Don't stay too long, or you will doze off in class.

You can do more exercise in the afternoon or evening. If you want to keep fit, you can buy a dumbbell. Can be used for arms, chest, back and shoulders, which is more cost-effective than going to the gym. Ha ha.
