To perform a set of side plank:
Lie on your right side with your elbow under your shoulder, trunk in a neutral position and your legs fully extended.
Squeeze your obliques and push into the ground with the outside of your right foot to raise your body off the ground. Your body should be supported by your right elbow and right foot only. It is important to have alignment of your shoulders, hips, knees and ankles.
Continue squeezing your abdominals and keeping your legs extended for as long as described or until you can no longer maintain the alignment of your body. If you are unable to start in a neutral position, it is recommended to do an easier variation first.
Remember to breathe normally throughout the entire movement.
Repeat steps 1 through 4 until you have completed the desired number of side plank repetitions.
This completes one set of side plank.
