Get a jog/weights in whenever you can. Doenst matter how less - even a short 200 m light run will help. Dont over do it - if any body part is sore, let it rest. Jogging even a very short distance, kills any craving i have for junk food. Also helps clear up the mind and helps make important decisions. Also imo, nothing beats a regular Yoga practise if you are able to find time/coach.
