Mike decides to do more pull-ups to increase his strength for climbing. He uses the greasing the groove technique where every time he goes into a certain room he does 2 pull-ups. He decides to use his office. He goes in there 5 times a day every day. How many pull-ups does he do a week? Think carefully first, then make a decision:
He does 5 * 2 = 10 pull - ups a day. So he does 10 * 7 = 70 pull - ups a week. So, the answer is 70.
