Researchers studied 71 adults aged 40–69 and compared a personalized exercise program to a control group.
The personalized plan adjusted workouts based on each person’s age, fitness level, and activity history. Over the course of the program, researchers measured changes in muscle mass and body fat.
The results were clear:
Participants following the tailored exercise program gained more muscle and lost more body fat than those in the control group.
Bottom line:
Personalized exercise routines are more effective than generic, one-size-fits-all workouts—especially for middle-aged adults who have different fitness needs and starting points.
