I found People's Republic of China 4-minute Exercise Plan[1] at a thrift store a little while back and have been trying to do the routine a few times a day. This is an exercise plan that was developed by the Chinese government and every morning everyone in China would do this exercise plan before getting their day started (back in Mao times).

The exercises are a little different than western exercises (there is some punching and kicking), but it's a great full-body workout and super-easy to fit in during a commercial break or while your npm packages install.
