You don't “break” or “Stop” bad habits. You REPLACE them with GOOD habits. Here are the steps:
1. Identify the bad habit
2. Look at the pros and cons of continuing this habit.
3. Plan a new action.
4. Practice the plan
This will take time, but eventually you will not have to even think about this. It will just happen. You will have successfully replaced the bad habit with a good one.
I also talk about how the more muscles you have the more calories you burn. However, the best exercise to do is the exercise that you WILL do. Just get in the habit of exercising. We can mix it up later. Speaking of mixing it up check our Jorge Cruise 8 Minutes in the morning kit (link at shop.logicalloss.com)
