What if I told you that you could retain or even gain more muscle mass and strength with less training? The secret lies in your nutrition.
As a personal trainer, most of my clients exhibit similar behavior: they train hard, but they don’t give a damn about nutrition. So the time and effort they spend on training is wasted. Why do they sabotage their own success? Because they think nutrition is complicated and want to avoid the topic.
