Body Power Lab

On Monday, Lilly, Rose and I did the body power lab. In it, we calculated our resting heart rate, our working heart rate and our maximum heart rate. If you are working harder, you are working at a higher percentage of your maximum heart rate. If you are working at a higher %MHR you burn more calories. Lily and Rose are much smaller than me. They both burned more calories than me because they had higher heartbeats because they are smaller. We didn't have enough time to do much of the Lab, because the calculations took a while (I had to do them all).
This will be useful because on our mission, we are going to need to keep in shape because we are going into a "zero gravity" environment. Theoretically, it would take no effort at all to lift anything so we have to keep in shape using other methods.
