Sit Ups with Russian Twist
Start lying on your back with your knees bent and feet flat on the floor. Arms are bent and in front of your abdomen or chest.
Engage your core by pulling your belly button in towards your spine. Keep your core engaged throughout the exercise.
Once at 45 degree from the floor, wist your upper body to one side and then to the other. Make sure to keep your lower back pressed into the floor as you twist.
Slowly lower back down to the starting position.
Make sure to keep your movements slow and controlled. Avoid jerky motions.
Focus on using your abdominal muscles to lift your torso up rather than pulling with your arms or neck.
Exhale as you sit up and twist, inhale as you lower back down.
Take breaks in between sets if needed. Make sure not to overexert your core.
For added resistance, you can hold a lightweight medicine ball or dumbbell as you do the sit up and twist motion.
