| 1 The scissors increased my heart rate the most. Because it was all a cardio workout. 2 Sitting still increased it the least. This was because I was resting. 3 Yes it was accurate. Because the rank ordered it in was what it was. 4 I noticed that it sped up. Because the heart needed to pump more blood. 5 I think it changed because it had to pump a lot more blood. That makes your body speed up. |
