After years of chronic back and neck pain—and his heaviest weight ever—Robert Wilhelm used structured challenges, disciplined training, and consistency to reclaim his health and strength.
Like many people, the years following the COVID pandemic slowly pushed Robert Wilhelm off course. Training became inconsistent. Weight crept up. Then it piled on.
“I found myself getting more and more out of shape, hitting my heaviest I have ever been—205 pounds,” says the 43-year-old. “None of my clothes fit, I had a hard time sleeping, it was uncomfortable to do simple tasks, and the list goes on.”
By April 21, 2025, he decided enough was enough. He stepped on the scale at 190.4 pounds and committed to starting over—this time with structure.
“When I saw the SS8 (Summer Shred) Challenge , I said to myself, this is what I need,” Robert says. “Having a hard time doing it on my own, I knew a challenge would trigger my brain to an entirely new level.”
Robert approached the Summer Shred Challenge with a clear goal: not just weight loss, but long-term health and sustainability. “My overall goal was and still is to maintain a healthy weight and a healthy lifestyle so that I can do the things I love,” he says.
This motivation is rooted in a military background that wasn’t always kind to this body. A U.S. Navy veteran who served from 2000 to 2006, Robert currently supports the military as a Federal Government civilian, working for the Marine Corps as a Lead Engineer. But years of service left a mark. He’s dealt with chronic back and neck pain for more than two decades. And while staying active never eliminated it completely, it became clear that not staying active made everything worse.
“While staying in shape does not alleviate all my pain, it does help manage it,” he says.
Following the workouts and nutrition guidance provided through the app, he committed to a strict but realistic diet and training regimen. By the end of the challenge, the scale was moving in the right direction. But more importantly, his body was responding in ways that mattered more.
“At the end of the Summer Shred Challenge, my back pain had started to become more manageable,” Wilhelm says.
And he wasn’t done yet.
Determined to push further, Wilhelm entered the ensuing JimStoppani.com challenge (the HIIT 100 Challenge , aka Holiday Shred Challenge) with one clear target in mind: getting his bodyweight back into the 160s.
He started the second challenge at 178.3 pounds and finished at 169.6. “I did it. I hit the 160s!” he says.
Despite the weight loss, Wilhelm noticed something else happening. “I’m stronger than I ever have been,” he says. “Despite the weight loss, I know I put on a bit of muscle mass as well.”
The consistency paid off—especially where it mattered most.
“These challenges allowed me to get down to a good weight and build strength, most importantly in my core and back,” he says.
Perhaps the biggest validation came not from the mirror, but from his back doctor.
“My most recent visit went crazy well,” Robert says. “He told me that I’m probably the healthiest person he sees and to not come back unless I have another spasm.”
The doctor was impressed by Robert’s weight loss, muscle gain, and improved range of motion—and even admitted the progress motivated him personally. “That really meant a lot,” Robert says.
The reactions didn’t stop there. Family, friends, and coworkers noticed the change and wanted to know how he did it. Robert didn’t hesitate to point them in the same direction.
“I passed on the Jim Stoppani Workout App and explained to them how they can use it to complement their own goals,” he says.
The journey wasn’t flawless. Training with chronic pain—and an aging body—required adjustments.
“Now that I am older, I found it most difficult to understand my older body,” Robert says. “I was fighting back spasms, neck pain, and realized my joints were not as they used to be.”
That meant more mobility work, smarter load management, and listening when his body pushed back. His biggest fear was injury—and late in the Summer Shred Challenge, that fear became reality. “On my last week, I pulled my groin playing softball,” he says.
Still, he finished the challenge, modified when necessary, recovered faster than expected, and came back stronger during the Holiday Shred Challenge.
“What I found out is that due to me being in better shape, I was able to recover a little faster,” he says.
Robert is the first to admit the process wasn’t easy—but he’s also clear about what makes the difference.
“This transformation was not easy,” he says. “Like anything, you must put the work in and push yourself past the limits of what your brain is telling you.”
His advice to anyone considering a challenge or structured program?
“Any workout plan or diet is only as hard as you make it,” he says. “How far are you willing to push your body?”
There will be setbacks. There will be tough weeks. What matters is staying the course.
“You will have up and down weeks,” Robert says. “The most important thing is that you stay on pace and push through the physical and mental pain of the journey.”
Robert isn’t done. Not even close.
“I will continue my fitness journey and participate in the challenges,” he says. “I’ve just signed up for Xtreme Shredded 8 (XS8). I am excited to see where this program takes me.”
At 43, with decades of chronic pain behind him and a stronger, healthier body beneath him, Robert Wilhelm isn’t chasing perfection. He’s proving that with structure, discipline, and the willingness to push through discomfort, it’s never too late to take control—and keep moving forward.
