Jennifer Lopez is known to the world as many things — a singer, actress, designer and entrepreneur — but six months after adding “mother” to that list, the 39-year-old is taking on yet another daunting challenge.

Months after giving birth to twins Max and Emme with husband Marc Anthony, Lopez hit up Good Morning America today to announce that she plans to run, swim and bike her way around Malibu at the 22nd Annual Malibu Triathlon next month.

According to Self magazine, La Lopez gained 50 pounds when carrying around her now 6-month-old twins. Now she says she’s still a few pounds over her pre-pregnancy weight, but the pop superstar has been working hard to get back into shape.

Here are some tips courtesy J.Lo:

Tips on Getting Started: “You got to start slow, give yourself time. This is not something natural to me. You have to start little by little and work up.”

Tips on Running: “More traction on the road means more forward momentum. And use your arms to pump back and forth so you keep your [foot] turnover quick. Light feet. No heel pounding. Strike midfoot and roll forward and you’ll not only go faster, but you’ll save your knees and joints from injury over time.”

Tips on Biking: According to Danziger, before even beginning bike training, getting outfitted with the right size bike is very important.

“Let the bike store person fit you personally to avoid aches and pains in shoulders and back, and also to get the most out of your pedal stroke,” she said. “Also, use your gears to make it easier to spin at a high cadence and save your leg muscles from fatigue.”
