Side crunches exercise the external obliques
When the abdominal muscles are trained to 4 packs, you can practice the external obliques, which can make the entire abdominal muscles more perfect.
Lie on your side on the ground with your knees bent at 90 degrees. Stretch one arm and place it on the ground to maintain body balance, and bend the other arm next to your ear.
Inhale and lift the body up to the highest point, exhale to return. Tip: Try to avoid using the arms that keep your body balanced to help lift your body.
