How to do: Tuck Crunch

Step-by-step instructions

1. 1To begin, lie down on the floor or an exercise mat with your back pressed against the floor. Your arms should be lying across your sides with the palms facing down.
2. 2Your legs should be crossed by wrapping one ankle around the other. Slowly elevate your legs up in the air until your thighs are perpendicular to the floor with a slight bend at the knees. Note: Your knees and toes should be parallel to the floor as opposed to the thighs.
3. 3Move your arms from the floor and cross them so they are resting on your chest. This is the starting position.
4. 4While keeping your lower back pressed against the floor, slowly lift your torso. Remember to exhale while perform this part of the exercise.
5. 5Slowly begin to lower your torso back down to the starting position while inhaling.
6. 6Repeat for the recommended amount of repetitions.
