Question

In which stage of the transtheoretical model of exercise program adherence must the participant be most vigilant against a relapse into physical inactivity?

Answer 1

In the transtheoretical model of exercise program, the participant must be most vigilant in the fourth (4th) stage against a relapse into physical inactivity because it is the least stable stage. The fourth stage is the stage when the participant has been exercising consistently, but for less than 6 months.
