4. Take resting pulse rates of each person at the carotid artery on the neck and record results
5. Have each person do 8inch step ups for 4 minutes
6. Wait 30 seconds
7. Take pulse rate and record
8. Work out the % increase or decrease of the resting pulse rate with the new pulse rate, record
9. Repeat steps 1-8, this time with different exercises- running on the spot and sit ups
10. Repeat steps 1-9, this time with water, not Gatorade on a different day
