Seriously, power through the 9 weeks! You will never regret it.
Allow me to paint you a word picture:
5'9 male weighing in at 16 stone, fat boy with a fat red face who smokes near enough 20 a day and has a diet that consists of:
Breakfast: Leftover pizza from last night
Lunch: Chicken Palace (KFC's nasty, cheaper baby brother)
Dinner: Large Pizza, garlic bread, other extras. Leave a few slices for breakfast.
Snacks: Chocolate, crisps, coke, redbull relentless, well over 2 pints of coffee, dough-nuts, pretty much ANY sweets that are reduced in price from Sainsburys.
All day, every day. No exercise since birth. I'm serious, nothing, ever none.
Today, that 5'9 guy weighs 12 stone, and is still losing fat. Runs a 5k in about 25 minutes, hits the gym 3 times a week, runs 3 times a week, eats all healthy, is starting to get a nice bit of muscle definition and is about to join the RAF.
And all it took was 18 months, the first 9 weeks of which were Couch To 5k!
