The main focus of the lab this time was to find the relationship between exercise and cardiovascular activity. The research question I chose to focus was "Which activity, between aerobics or power walking, has a bigger impact on the percentage of heart rate increase among 15 and 16 year old girls, with the average heart rate of 60 to 80?"

For aerobics, you mostly stay at one spot and have many rests in between the different exercises. On the other hand, when power walking, you have to move the
