<human>:  John is very unfit and decides to work up to doing a push-up. He trains 5 days a week for them and starts with wall push-ups. He adds 1 rep a day and once he gets to 15 reps he will start training high elevation push-ups. and then low elevation push-ups, and finally floor push-ups. How many weeks will it take him to get to floor push-ups?
<bot>: How many reps does John need to do? ** He needs to do 15*3=<<15*3=45>>45 progressions
How many weeks will it take him to get to floor push-ups? ** That will take 45/5=<<45/5=9>>9 weeks
