The ladies in Olympic legend Michael Phelps' life

: USA swimming sensation Michael Phelps is now the most decorated Olympian of all time. Phelps has always acknowledged and emphasised the importance of his mother Debbie and his sisters Whitney and Hillary. Phelps began swimming at the age of seven, partly because of the influence of his sisters and partly to provide him with an outlet for his energy.
