It definitely doesn't hurt. You would only recognize how much good its doing you if you stopped.
I did 20 minutes on my treadmill , 4 days a week, and lost about one pound a week.
Yes!
No.
Yes. 100% true if you walk briskly for 45 minutes daily for five days a week.
Cannot be answered if we do not know how much soda you replace. If it's 3 12-oz Cokes a day, that's say 500 calories; about 100 calories if you are 150 pounds when walking the treadmill for 30 min, so about 600 day; you need to save about 3000 cal to lose a pound. This means in 5 days, you might lose a pound. Keep at it.
1 week 5 days 18 hours 55 minutes
1 week = 7 days = 168 hours = 10080 minutes
8 days = 192 hours = 11520 minutes
60 minutes in an hour 24 hours in a day 7 days in a week. Equation: 60 x 24 x 7 = 10080 minutes in a week
There are 60 minutes in an hour and 24 hours in a day and 7 days a week so that is: 60x24x7=10080
For 4 days only, don't expect much. With a really strict diet, and hitting that treadmill hard and long, maybe 3-4 pounds. Most of which will spring right back the next week.
Four hours and 35 minutes five days a week totals 22 hours and 55 minutes each week. This is calculated by multiplying 4 hours and 35 minutes by 5, which equals 22 hours (20 hours from the 4 hours multiplied by 5) and 55 minutes (35 minutes multiplied by 5).
