It may seem easy, but there is no simple or guaranteed route to becoming a fitness model or celebrity trainer. But Lauren Drain, who has been a registered nurse for more than 8 years, according to her website, has clearly harnessed the secret to success. She only began to take fitness seriously when she noticed that “life was spiraling out of control. I was overworked, overstressed, overweight, sleep deprived, fatigued, and extremely unhappy before I finally decided to take control of my life and get my priorities straight. I wanted to be a healthy, fit, strong, confident woman.”

Drain has since made a change for the better in her lifestyle, and now she’s a well-known Instagram fitness model and workout inspiration with 3.8 million followers.
