Start this exercise by laying on all fours. Your hands should be flat on the ground and your arms should be straight down. Keep your back straight and bend at your knees so your legs come straight back of you. Your knees and toes should be on the ground.
In this position, draw your lower abdomen up towards you. Don’t forget to breathe while doing this.
If the exercise is performed correctly, your lower abdomen will elevate before your upper abdomen does.
Repeat in a slow and controlled motion.
