Real Boxing. Real Community.
Lion's Den Boxing Gym was built to give Pittsburg something real: a boxing gym that serves the community and takes the work seriously. A place where kids build discipline, teens find direction, and adults train in a room that feels honest from the minute they walk in.
It's a 501(c)(3) nonprofit — the mission goes beyond training. The gym exists to give local kids, teens, and families a real place to grow through discipline, structure, and community support.
Programs
Every goal has a program. Every level has a coach.
Give your child discipline, confidence, and a strong place to grow.
Youth classes teach stance, movement, defense, and focus in a coach-led setting that feels structured and safe. Parents come here because they want more than exercise — they want mentorship, accountability, and a place that helps their kids grow up stronger.
Get Your Child Into Class
Give teens a real outlet that pushes them in the right direction.
Teen training is built for students who need discipline, confidence, and a harder standard than they get from a typical gym. Whether they want to compete or just stay sharp and grounded, they get real coaching and real expectations.
Book a Teen Intro Class
Train hard before work or after work without wasting time on fake boxing.
Adult classes are for people who want skill, conditioning, and stress relief in a room that takes boxing seriously. Lion's Den is especially strong for adults looking for morning classes before work and a better option than generic fitness gyms.
Join an Adult Class
Follow a real path from beginner work to amateur competition.
Most local gyms talk about fighters. Lion's Den can actually show you what the path looks like. If you want to box competitively, the coaching here is honest about where you are, what needs work, and what it takes to get ready.
Ask About the Amateur Path
Get focused instruction and faster progress with one-on-one coaching.
Private sessions are ideal for beginners who want a strong start, busy adults who need a flexible schedule, or fighters cleaning up details. You get direct coaching, specific corrections, and a session built around your actual goals.
Book a Private Session
Cross-train in Muay Thai, MMA, and BJJ through Lions Den's partner program with Coach Dan Black.
Lions Den members who want more than boxing can plug into the Team Black partnership for striking, grappling, and full mixed-martial-arts development while keeping Lions Den as their boxing home base.

What Members Say
My son needed discipline and confidence more than anything, and this gym has helped with both. The coaches are firm, but it still feels like a safe space, and that matters a lot as a parent.
The morning classes fit my schedule before work, which is the only way I was going to stay consistent. I like that there is no contract pressure and no fake sales pitch when you walk in.
My daughter trains here, and now I do too. It feels like family, but not in a corny way. People work hard, coaches hold you accountable, and everybody from kids to adults gets treated with respect.
