Fitness coach and entrepreneur Dan Go outlined a simple but powerful formula for slowing the aging process in your 40s, emphasizing that small, consistent habits can dramatically shift the trajectory of physical and mental vitality.

“How to slow down the aging process in your 40s,” wrote Go in a LinkedIn post. “Strength training preserves muscle and metabolism. Daily movement keeps joints, heart, and brain sharp. Quality sleep repairs your body. Whole foods fuel it right.”

He also highlighted the importance of blood sugar control to prevent energy crashes and slow biological aging, along with stress management to protect hormonal health. Exposure to natural sunlight, he noted, helps set the body’s circadian rhythm, promoting better sleep and metabolic function.

Together, these foundational practices can make 40 feel more like 25, according to Go. His message pushes back against the idea that aging inevitably means decline, reframing midlife as an opportunity to reset and optimize.

“Take care of your engine, and 40 becomes the starting line, not the finish,” he wrote.
