Just over 10 weeks ago I was very lazy and the only exercise I did was walking my daughter back from nursery, very slowly.
Now, I have just managed to run 5km in 31 minutes (my first mini goal is to do it in 30 mins), I've lost over 2kg (just over 5lbs? I don't do pounds anymore...), I've lost 7cm (about 2.5 inches) from my waist and my resting heart rate has gone from 85 bpm (not good) to 65 bpm (not bad).
Admittedly I have also started eating less because I've got braces on my teeth now, so that could account for the weight loss, but still, the numbers are enough to keep me going!
I also sleep better and I have way more energy (my daughter has learnt to ride a bike without stabilisers and I can run along with her).
If you're at the beginning of this journey and you feel like you can't do it - you can! And when you see little changes in your body or your mind, it'll hopefully spur you on.
I'm still on a post run high - I'm sorry
