Hi GD mothers, how do you all find the time to walk for 30 mins after each meals and snacks ?

Hi GD mothers, how do you all find the time to walk for 30 mins after each meals and snacks ? The ODAC was asking me to walk 30 mins after every meals and snacks. That's like 3h in a day. Need to work in office, can't find the time to walk actually. How do you all cope with that to lower the blood sugar level ?
