So with all that stuff taking time to prepare, what to do with the two minutes that it takes the microwave to heat something? It's not enough time to go back to reading my book. It's not enough time to go back to preparing other things for a meal. After all if a cup of soup is in the microwave, it might boil over, so there I stand watching the turntable inside while the soup heats. It became obvious that it was a perfect opportunity to do a little multitasking while keeping an eye on the contents in the microwave. It isn't multitasking in the truest sense of the word, because I'm just watching the microwave do something and I want something to do while I watch it.
In the two minutes that it takes to heat a cup of water for tea, it is possible to do 50 lunges. Jumping jacks make a good choice, because one limits the time one does those anyway. Squats are easy to do in place while watching the soup or cup of water rotating around inside the microwave. Stretching exercises are quick and easy to keep busy and make good use of the time spent watching the microwave. I like put my hands behind my head, which bends my elbows, and lift the opposite knee to touch elbow to knee, alternating sides to see how many I can do in one minute. Sometimes for variety, I side-step back and forth across the kitchen and count how many I can do in the two minutes before the tea is ready.
