Interventions/Control_1

A four-week exercise program combining SDT and HAPA will be implemented. The content of the exercise program will be discussed between the researcher and the pregnant woman, and the specific details of the exercises, including the content, duration, timing, participants, and location, will be decided. The agreed-upon content will be recorded in a booklet. The exercises performed during the period and the time spent on them will be recorded in a booklet created by the researchers.At the two-week mark from the start of the exercise program, the exercise content will be reviewed by the researcher and the pregnant woman.

Interventions/Control_2

The control group will be given explanations about the types, intensity, and duration of exercise recommended for pregnant women, and will engage in exercise for four weeks. Participants will be asked to record the exercises they performed and the duration of each exercise in a booklet created by the researchers.
