Jamie Warren has made a career getting and keeping people in shape on their health and fitness journeys. The CEO of Birmingham’s Iron Tribe Fitness runs a business that has a model that treats those customers like important individuals and close friends. Ultimately, that philosophy–and Iron Tribe’s success–stems from Warren’s Christian faith. “As Christians, we are called to steward our bodies and that’s what we do in our business. But, more than that, we’re loving on people,” Warren said. “We speak the love of Christ, whatever their background is. And we’re always cheering them on.”
God’s Guiding Hand. According to Warren, God’s fingerprints have been “all over” his journey. Things that some people might call coincidences led Warren to his career with Iron Tribe. He first met the founder and former CEO of Iron Tribe Fitness in a small group Bible study at The Church at Brook Hills in the late 1990s. Forrest Walden and his wife Mendy became friends with the Warrens through church and a shared interest in fitness. “Forrest was my fitness friend. He was in great shape, and I looked up to him,” Warren said. “We had them over for dinner, and he wandered into my office and noticed the books on my shelf. We discovered that we read the same things, and that was sort of the start of a deeper connection.” Warren became a client at Fitness Together (an early one-on-one training concept developed by Walden). Warren and Walden continued to attend church together, built a friendship, and then saw Walden go through what he called a “crisis of belief” stemming from a sermon from their pastor at the time, David Platt. “David asked us, ‘Are we really going to make our lives count?’ We had this idea that we needed to connect Kingdom work with what we were doing with our vocations,” Warren recalled. 
One of the results of that eye-opening revelation was for Walden to bring “Never Thirst” (a clean water ministry alongside the Gospel) to unreached parts of the world. Walden invited Warren to take part in a Never Thirst trip to India as a still photographer. It was there that Warren first fell in love with the Iron Tribe concept. “I saw Forrest working out at the end of the hotel hall. He was running up and down stairs, doing burpees, and I worked out with him. I got destroyed,” he laughed. “But I joined a group of 12 people who worked out together in Homewood. It was eye-opening.” Walden brought the idea of Iron Tribe–a gym that has a limited membership per location, and focused on individualized attention–to their workout group, and Warren, who had already made a silent investment in a gym in Nashville, convinced investors in that deal to switch to an Iron Tribe franchise. Warren sold his prior business (a boutique marketing agency) in 2014 and worked full-time as a franchise owner in Nashville with four Iron Tribe locations. When Walden was ready to retire, Warren purchased the business, and he now owns the brand, the franchise company, and four individual gyms in Birmingham.
Today, the Iron Tribe name remains synonymous with a personal touch–something that Warren said is extremely important and yet rare in the fitness world. He said that the typical image of a gym is one with thousands of members and a sea of machines–but it’s a place where many members don’t even show up to work out. “We never have more than 300 members, because we want everyone to show up all the time,” Warren said. “At Iron Tribe, you have a personal relationship with your coach, and you get to know everyone who is in your classes. Because of those relationships, you show up three or four times a week, and you’re excited to be there. You’re doing things you never thought possible, getting stronger, and having fun,” he said, adding, “When you do that, there’s a bond. People in the gym become fast friends.”
A Business & Family Built on Faith. Faith drives all of the decisions made in both Warren’s personal and professional life. He often turns to Psalm 67:1-2 for direction. “That verse asks God to bless us, to make His face shine upon so, so that His name shall be known among nations,” he said. “Our philosophy is that a faith foundation changes everything. Because we want to be open to and help as many people as possible in our business, it attracts a certain kind of people.” Iron Tribe, he said, is focused on people and operates by the core values of compassion, teamwork, integrity, and service. “That creates a gym experience that’s going to be different than so many others,” he said. “They stay with us because they get results, but also because they feel loved and seen. If we can show the love of Christ to people and treat them in a certain way, they’ll get fitness results but will also have their lives changed because of how they’re treated.” Warren’s personal and family life is built on a similar faith-filled foundation. He and his wife, Julie, were both raised in the church by Christian parents, and while attending college together, they began to grow in their faith. They soon learned that being a Christian was more than just adhering to a religion; it was about having a real relationship with Christ. Then, when they married and began their family journey, they experienced challenges that taught them even more about their faith. As parents of a special-needs child and as career-driven individuals with plenty of professional challenges, the road wasn’t always easy–but it has, Warren said, always been guided by grace. “Our marriage hasn’t always been easy, but we are walking pictures of God’s grace and faithfulness,” Warren said. “Having a child with special needs and also being an entrepreneur for 20 years and all the chaos that comes with that…it can be challenging.” Warren said that he and Julie have always had as their goals to raise their sons in a Christ-like environment and to live all aspects of their lives as God would desire them to. “Our marriage is centered in Christ, and we have always tried to raise our children into Godly men. That’s the whole goal,” he said. “I want to run and lead a business and home that honors God.”
A Love for Birmingham. Warren was born in Montgomery but moved to Birmingham when he was just 4 years old (when his father moved out of work with the Air Force National Guard and took a job in the Magic City). He was raised in Vestavia, graduated from Vestavia High School, met his wife at Furman University, and then moved back to Birmingham in 1997. They’ve been here ever since, raising their family and building his career. “I’m still up in Nashville multiple times a month and visiting gyms,” he said. “In Birmingham, I move around a lot and work out in a different gym in town every day. We have a fantastic team in Birmingham.” He and Julie have been married for 28 years, and they have three sons: Jackson, 22; Jonathan, 20; and Joel, 16, a student at Homewood High School. After being members at The Church at Brook Hills for many years, they moved in 2017 to Haven Field (a church plant of Dawson Baptist Church). They’re involved in a variety of ministries and call the church “the kind of place we needed to be for our family.” As for the future? Warren said he plans to continue to act in obedience to God’s call on his life and in his business. He encourages individuals to do the same in 2026–whether in their family life, spiritual life, or fitness life. “At the beginning of the year, a lot of people are thinking about setting goals and making changes,” he said. “One thing I learned from Forrest is that the most important thing when you’re doing that is to think and pray about it. Don’t make changes for superficial reasons. Ask yourself: what’s the real reason I want to do this? It’s important to have a compelling reason to change or set goals. Then, you can stick with it.” Acting in obedience to God’s call will ultimately make things happen. That’s where Warren believes his success has come from. “Iron Tribe is here because of an obedience to look at it as God’s business,” he said. “Out of obedience came a special brand that God has uniquely prepared for me over the decades. I own the business now, but it’s a stewardship model. We’re here only because God has given us the opportunity.”
