PINEHURST, N.C. — In a room so loud you can barely hear yourself think, you will find what some call the ultimate workout.

Body Pump is the newest craze at FirstHealth Moore Regional's Center for Health and Fitness.

It is a weight lifting program set to fast-paced music. The combination gives people something that is hard to get -- strength training and cardio all in one exercise program.

"You're working your strength in your weights at a cardio pace," participant Andy Bribey said.

Women dominate the daytime classes. For many, it is their first experience with weights.

"They're getting that strength training and a lot of them have never done it before and they're loving it -- absolutely loving it," instructor Jodi Heimrich said.

It is the opposite for most men, who need cardio exercise.

Janice Phillips admits that first workout is brutal.

"[You are] really, really painfully sore the first time," she said.

"The nice thing about this class is you can start with a lighter amount of weight and then increase the weight as you get stronger," Kari Garback said.

Phillips is hooked. She does Body Pump three times a week.

"I almost have a muscle," she said.

With so many people hooked, the hardest part of this workout may be finding room to get in.

A growing number of fitness and wellness centers are adding Body Pump programs. Since it is a strength training program, it is recommended that you do it two to three times a week with at least one day of rest between workouts.
