How many minutes does he spend warming up? ** He spends 60/3=<<60/3=20>>20 minutes warming up
How many minutes does he spend at the gym each day? ** So he spends 60+20=<<60+20=80>>80 minutes at the gym per day
How many minutes does he spend at the gym in a week? ** That means he spends 80*3=<<80*3=240>>240 minutes at the gym
How many hours does he spend at the gym a week? ** So he spends 240/60=<<240/60=4>>4 hours at the gym a week
