Lauren Conrad's personal trainer spills her workout secrets

Jarett Del Bene

has been credited with getting Lauren Conrad, Audrina Patridge, Whitney Port and Lo Bosworth from The Hills in photo-op shape. Here, he shares how he helped sculpt the reality-TV stars and what you can do to get a red carpet-worthy body.

Q: How did you help Lauren get trim and toned?

A:
We started off doing circuit-training three days a week and she did cardio workouts on her own. In the past couple months, Lauren and Lo and I have been combining cardio kickboxing and circuit-training into one workout. We start with 20 to 30 minutes of high-intensity boxing. The girls hit my focus mitts and do jumps and kicks. Then we mix in weight moves, such as lunges, squats, push-ups and sit-ups. It's a great full-body workout that relieves stress and builds confidence.

Q: Lauren and Audrina are regularly filmed in bathing suits. What tips do you have for getting bikini-ready abs?

A:
My philosophy is to train the body as a whole and the abs will come. People think they need to do hundreds of sit-ups a day to get six-pack abs, but if you're doing the right kind of strength-training moves (exercises that challenge your body to stabilize itself while you're working with resistance), you're constantly using your midsection.

Q: How can people make the most of their time at the gym?

A:
Definitely have a plan when you walk in. A lot of people waste time trying to figure out what exercises to do. Go in with your workout mapped out. As you're commuting to the gym, decide if you're going to do cardio. If so, what machine, for how long and at what intensity? If you're planning to do weights, decide if you want to work your whole body or focus on certain muscle groups.
