Turning 40 doesn’t mean you’re slowing down—but it does mean your body changes. Testosterone begins to decline, it’s harder to maintain muscle mass, and joints may not feel as flexible or responsive as they used to.

If you’ve noticed more fatigue after workouts, slower recovery, or changes in body composition, you’re not alone. These are common—and manageable—with the right approach. 

Regular training helps, but so does nutrition and targeted supplementation. With the right support, you can stay strong, energized, and active well into your 40s, 50s, and beyond.
