What this is — and what it isn't.
Most fitness programs fail because they're solving the wrong problem. They give you a plan when what you actually need is a foundation. A different relationship with food, with your body, with the data on the scale.
BPR is not a diet. It's not a training plan. It's a system for becoming the kind of person who naturally maintains the body they want — because the behaviors that produce that body have become who they are, not what they're forcing themselves to do.
The techniques are simple. Deliberately so. Simple outperforms complex under pressure, and life will apply pressure.
