The rules are:
2 x 45 minute workouts a day. One must be outside (a dog walk counts).
Stick to a healthy eating plan of your choice and strictly no alcohol.
Drink 1 gallon of water a day.
Read 10 pages of a non fiction book every day.
Take a daily progress pic.
I'm planning to do 45 minutes of yoga every morning and a dog walk in the evening. I already eat quite healthy but I will cut out the sugar and switch to an oat milk without oils/additives as I drink gallons of the stuff.
