There’s this thing in fitness called the SAID principle, which stands for “Specific Adaptations of Imposed Demands.” It means that your body adapts to the demands placed on it.
So in the context of achieving goals, if you want to get rid of low back pain, tone your core, shape your glutes, or do a pullup for the very first time…
your routine MUST be specific to these goals and not a random hodge podge of workouts. Every day. Every week. Every month. Until the goal is achieved.
If you want to achieve your goals then don’t violate the SAID principle.
