SIT UP INSTRUCTIONS
1. Lie down on your back, keep your knees bent and your back and feet flat on the mat.
2. Slowly lift your torso and sit up.
3. Return to the starting position by rolling down one vertebrae at a time.
4. Repeat the exercise until set is complete.
PROPER FORM AND BREATHING PATTERN
When doing sit ups, keep your abs engaged, your chest open and your shoulders, neck and back relaxed. Breathe out as you crunch and use only your ab strength to lift your torso up. Inhale as you slowly return to the starting position, rolling your spine one vertebrae at a time.
Including sit ups in your workout routine helps to sculpt and tone your abdomen and trims down your waist. Both the sit up and the crunch target your abs and, because sit ups involve a greater range of movement, they also work your hip flexors, chest and legs.
