I hope it's okay for me to start a challenge...
The best time of year is coming! The outdoors will be changing and so will we, for the better. It also means that it's finally cooling down outside, so outdoor exercising won't be so horrendous (especially if your neck of the woods had record highs and weekly heat advisories all summer).
It'll officially run from September 1st to November 30th. I know autumn doesn't officially start until Sept. 23, but 1.) as soon as the calendar says September, it's fall to me and 2.) it gives us an even three months to achieve whatever goals we set.
So, to start off:
1.) Cut down soda and drink more water & tea (since I can now justify drinking hot tea!)
2.) Go for protein/vegetable meals and cut down on carbs
3.) Exercise 3-5x/week
4.) Abstain from fast food
5.) Regulate sleep schedule (I'm up until 4AM and sleep until 1PM. Doesn't help I don't get home from work until 1AM).
