Pelvic floor activation during supported standing

Stand up straight leaning your back against a wall.
Your feet should be flat on the floor and hip width apart with your legs straight.
Focus on steady breathing throughout this exercise.
To activate your pelvic floor try to contract your anus, vagina and urethra inward and upward.
You can imagine that you are trying to pull a zipper closed with your pelvic floor from the bottom up.
