A 12-week exercise program can significantly reduce the number of senescent cells circulating in the blood.

“And we're starting to find that lifestyle and supplementation and some drugs can slow their formation; remember, keep the iron levels low; but also we can kill them off. And there's this study, the one you're referring to, which took 34 individuals for a 12 week exercise program and looked at the amount of senescent cells circulating in the blood immune system, and it was dramatically lower in the exercised people, arguing that you can actually kill off or reverse that process.”
