Rick Berghoff used to exercise by doing pushups and sit-ups in his home, but that changed 13 years ago.

In 1999, Berghoff’s wife, Roxanne, introduced the Fort Wayne man to Bodypump, a barbell class at Gold’s Gym, and he’s been hooked since. He now takes Group Power, a similar class that also uses high repetitions and low weights, two to three times a week – even when he’s on the road.

He usually takes the class at Spiece Fitness, 5310 Merchandise Drive, but the technician at ITT Exelis regularly seeks out gyms that offer Group Power or Bodypump when he’s traveling. He even attended classes while visiting family in Thailand.

“We went to a gym called California Wow and did a Bodypump class there,” Berghoff said. “It was wild.”

The workout: Group Power

What it is: According to Body Training Systems, Group Power is a barbell program that strengthens all major muscle groups. Group Power is set to music, and certain muscles are targeted during each song. The choreography changes every few months to keep the workout fresh.

What do you like about it: “I like working out with a group,” Berghoff says. “We talk and challenge each other. … It is kind of a workout/social hour.”

Difficulty: Group Power can be made difficult just by adding more weight and is appropriate for men and women of all ages.

Advice for beginners: Group Power allows participants to choose their intensity as they select their weights, and modifications are available. “Start out with light, light weights,” Berghoff says. “Get the proper moves down before adding more weight. Don’t get discouraged; the moves and rhythm take time to learn.”

Class length: One hour

Benefits: While classes with high repetitions and lower weights aren’t known for building muscle, Berghoff has done just that. Over the years, he says, his chest measurement has gone from 38 inches to 44. “And, you don’t have to wait for a machine like you do in the weight room,” he says with a grin.

Cross training: Berghoff swims on opposite nights of Group Power and rides his bike on the weekends. “(My wife) is a Spinning instructor,” he says with a smile. “So she says I ride slow.”

Motivation: Berghoff likes to stay active so he can keep up with his four grandchildren, and “I want to be healthy so I can someday enjoy my retirement.”

In Group Power class, the music is a source of motivation. “The rhythm gets my adrenaline flowing,” he says, adding that he often taps his feet along with the songs.

Future fitness goals: “ (The) goal is to keep doing what I am doing, as long as I can!”
