@kelvinteo93: For beginner that can’t do sit-ups, most of them may be because the explosive power of the abdominal muscles is not so strong, so they may not be able to go up. It is recommended to do Negative sit-ups first, and increase the speed of holding when slowly going down. It is recommended to do 3 sets of 10 reps. But when you can go down very slowly, you can try doing normal sit-ups again. #abs #6packsabs #situps #coreworkout #exercise #malaysia #Fitness #coach #personaltrainer #fyp #MCNMY23
