By Lori Williams – Eighteen-year-old Asher Knowles beat his odds when he stepped on stage at the NPC Las Vegas Natural Pro-Am Bodybuilding show in May 2025, becoming the hero of his childhood dreams and making history likely as the first TAR Syndrome bodybuilding competitor. As a child, he watched his mother, Sun Valley, Idaho’s bodybuilding icon, Emily Knowles, compete, then would cradle her trophies and dream about standing on that same stage.
Asher was born with Thrombocytopenia-Absent Radius (TAR) Syndrome, an extremely rare congenital disorder, characterized by low platelets and unique skeletal malformations, the most obvious being missing radius bones in each forearm, causing severely limited limb function. By the age of two, he’d had six surgeries to correct wrist alignment, leg bowing, and weak eyelid muscles. Asher faced a future filled with obstacles, but he refused to allow his condition to define him, and always found creative ways to adapt at every stage of life.
Despite being raised in a healthy fitness environment, Asher reached his heaviest weight at 176 pounds in middle school. “It seemed like overnight he went from a skinny kid to being overweight, which we thought might be the syndrome or a metabolic issue,” says Emily. The onset of puberty, a carb-heavy diet, and sugary snacks had all likely played a role, and his participation in competitive high school athletics only exposed the hard reality. He’d begun to notice on social media guys his age lifting and thought, how could I possibly do that? He told his mom he wanted to go to the gym.
After reading the book Forever Strong: A New, Science-Based Strategy for Aging Well by board-certified physician and nutritional scientist Dr. Gabrielle Lyon, Asher realized what power there was in precise nutrition within bodybuilding. He turned his weight-loss and fitness journey into his high school personal project and chronicled the transformation on social media. With trainer assistance, he designed his own macro diet plan, hypertrophy training, and weight-lifting program.
“Asher is without a standard arm structure,” says Emily. “When he began lifting, every move was questionable because with TAR everything is wired differently. It required adapting exercises, smart training with existing muscles, and his unique ability to compensate.” Once Asher began increasing his body’s muscle capacity, his grip strength improved. He began with a 25 lb. training bar, and days later would be able to do 35. In spite of distorted wrist flexion and grip strength, he could eventually execute pull-ups and bench lift, an extraordinary triumph. Adds Asher, “I wasn’t afraid of hurting myself. When I worked out, there was a push-through pain versus a scary pain, and I knew which was which.”
Asher was hooked on bodybuilding. His senior year, he decided to begin prepping for the 2025 Natural Federation show in Las Vegas, including the NPC Boise Muscle Classic held a week later, at which Emily was also competing. Asher strategically scheduled his trimesters, and front-loaded AP classes to balance a hectic senior year that would also include choir, swimming, and tennis. In the final trimester, he was allowed to use his second daily workout as a 4th period enrichment study, which was followed each day by cardio, swim practice, and finally, homework. 
The mother-son duo trained side-by-side, in a relentless grind of strict nutrition plans, custom workouts, and posing sessions. There were many off-ramps in his senior year, but with every workout and meal, he pressed on. He was deep into his caloric cut when May’s AP exams arrived. “Just to fuel my mental clarity, I would eat three of my five daily meals before I tested,” says Asher.
Enroute to Las Vegas, Asher had time to reflect. “It hit me just how far I had come,” he says. “I was living a literal dream. I knew I had done absolutely everything to prepare for this moment. It wasn’t like swimming, where if I kicked harder it would change the outcome.” When his first division was called he held his chest high and walked on stage.
Asher competed in Physically Challenged and won. He placed 4th in Novice, and 5th in Debut. 
The following week’s Boise Muscle Classic was Emily’s 22nd competition at 50 years old. No stranger to the podium, Emily has garnered 21 championship titles in two decades. “Competing next to my son is the victory that matters most,” she says. Emily took first in Masters Figure, and 2nd in Open Figure. Asher placed 2nd in Teen, and 4th in True Novice. At the end of Boise’s competition, the two were invited to do a pose down together, and then interviewed by four-time Mr. Universe, Mike O’Hearn. It was a historic, victorious flex.
Seven days later, Asher walked across his high school graduation stage, the Las Vegas medal entwined with Suma Cum Laude honor cords. The next day, he was back in the pool for two weeks of training for the USA National Para-swimming Championships in Boise. Asher is currently studying Exercise Science in college and swims on a club team, while continuing to build and maintain lean muscle mass for future bodybuilding competitions. Which is right where he hopes to continue shifting perceptions and setting a standard for physically challenged bodybuilding.
“I’ve never had the option of doing things an easy way,” says Asher. “But that’s never been the goal. I hope I’ve proven that strength isn’t just about muscle. It’s about heart, discipline, and the will to go further than anyone thought you could.”
