Rihanna’s fans may be sulking over her rapid body weight loss, but in showbiz owning flat abs is more important than any other body assets. Rihanna certainly exposed her secrets to getting flat abs quick upon her visit to Hawaii. Aside from puffing on some stuff she added the eliptical machine to her regimen, plenty of swimming and more than likely a lot of fish. Fish has a lot of Omegas which support leaner muscle tone as opposed to adding bulky muscles to one’s body. Rihanna gets props for motivating her NAVY team to get fit and fab before summer. Not sure about you, but we are all hitting the Eliptical machine.
