Jennifer Lopez lost 50 pounds – jealous? If you are, you should not be. While it is not easy to lose 50 pounds, it is not particularly hard either. Jennifer Lopez lost 50 pounds after giving birth to her twins, but the thing that separates her post-pregnancy weight loss from others is that thus far she was able to keep the weight off for almost a year, which is not easy to do.

Of course, like any other celebrity out there, she is not able to lose weight on her own. She has a personal trainer, Gunnar Peterson, and she uses a food delivery service called Freshology.

How Jennifer Lopez lost 50 pounds Her exercise and diet are pretty pedestrian. She exercises for about one hour at least a couple of days a week. Lopez’s typical workout includes a short warm-up, cardio and strength training.

Jennifer Lopez’s diet consists of anywhere from 1,200 to 1,400 daily calories, good fats, veggies, fruits, lean proteins and low-glycemic carbohydrates.

In addition, the following exercise tools help Lopez stay in shape:

Alter-G Treadmill The machine is enclosed in an anti-gravity bubble, which makes running easier and minimizes the pounding by reducing the pressure of your body weight up to 80 percent.

TRX Suspension Trainer It is a rather strange exercise contraption that helps Lopez do a variety of body-weight exercises.

Ropes Gone Wild “By lifting the ropes and then beating them against the ground for 20 to 60 seconds three to 12 times, Jen tones her core, hips, shoulders and butt,” says Peterson. [via]
