If you are looking for a place to train and work with certified and professional trainers to get the results you have always wanted, then head on over to C4. The team there is extremely knowledgeable when it comes to student athletes. C4 will get you ready for sports after high school and will help you secure opportunities with college or professional sport teams. If you are still in school and looking for major gains in whatever sports you play, then have C4 prepare you for your upcoming school year of sports.

C4 has been part of my son’s football career in the absolute best way possible. They have helped him grow into the athlete he is today. And, we have been honored to see C4 grow into the institution that it is today. From starting with Coach Chandler in his home, to moving into the space they are in today, Max has learned so much from these coaches! And, C4 has supported the community in ways that far exceed football, and every other sport that these athletes play and excel in! I wish I could give more stars!

My son has been training at C-4 for a little over 2 years. The crew there has not only helped transform his physical performance and on the field skills, but they have invested so much time in getting his mind set on goals and what he needs to do to achieve those goals. They work every aspect of an athlete to maximize every bit of ability. I highly recommend C-4 for all athletes looking to become the best version of themselves.

My son absolutely loves training at C4. He works out with like-minded athletes and he enjoys the coaching and the challenge.

The reason I couldn’t give 5-stars has nothing to do with the coaching but with the schedules and admin. My son was not only training but attending the weekly trench warriors and it was never clear nor communicated on when the program began and ended. We heard through another kid attending that TW was done and then I confirmed with the TW instagram account. I would much prefer this schedule be emailed or posted somewhere.

Also, it’d be great if you could do TW as an add on without having to do the training during seasons of other sports. This does not deduct in anyway just would be a nice to have.

My son will be returning to training at C4 as it truly provides a great way for him to grow his strength and SAQ

My daughter has been doing strength and conditioning training with Shawn at C4 Explosive Sports Training, and we couldn't be happier! Shawn has helped her heal and get strong again after a sports injury, and has helped her to take her basketball game to a new level since then. Shawn has been great for overall strength and conditioning training as well as future injury prevention. She is also consistently communicative, reliable, and has a great positive influence! Highly recommended!

My son has been a client for almost 1 year. He loves the coaches, the interaction with the other kids, and the training. Most importantly we see great improvement since he started. The coaches not only know and focus on what is important in the gym, but also what is important in life and pursuing goals.... Very happy with C4 and staff.

C4 is the place to be, period. After only 3 months, my son is bigger, stronger, quicker, faster, and better conditioned! And, we are not stopping any time soon. My son is also a better young man because of the C4 Team. Not only that, but if you are considering C4, your child will be around other legit athletes who come to work and that type of environment breeds greatness. They say that better training, makes better athletes. Well, at C4 it is Elite Training, with Elite Coaches. C4 has been the driving force for my son in developing muscle mass, maximum strength, and explosive power. Coach Brown has been instrumental in my son's life, first as a teacher, and now as his Coach at C4. Bottom line, I sent my son to C4 because I trusted them. I keep him there because they are Family, and neither I nor my son would be comfortable anywhere else! Like the sign says "Change Starts Here", so if you go there, you go to work! C4 is a no brainer, period.

C4 has reliable trained my team as a portion of our out-of-season activities for years. The team responds well to the coaches who push each athlete to work hard. The coaches are knowledgeable with regard to sport-specific training and consistently provided workouts that maximize each athletes full potential. I highly recommend C4 for either team or personal training.

Where do you start with a review for C4? Well like Charlie Chandler does and that is at the foundation. He and his crew build you and or your athlete up from the ground up, just like an expensive car or home or an awesome family. You get the best long-term result by building a great foundation and then putting what you want on top of that. I can attest that our daughter, who is a professional international soccer player, has utilized his facility numerous times and been the beneficiary of that process. She also has appreciated the flexibility of Charlie and his staff of working with her on the specific things she needs in order to compete at the highest levels of her specific sport. There is no "one size fits all" at C4, though there are programs there for that if you want that. They build you to "YOUR" specifications and that is the key to you being successful. If you are going to put in the work, why not go to C4 where you will get YOUR max result for your investment (in time and money)! Last but not least, your mindset is key in getting the most out of a good workout, and that is where C4 excels.... "best positive workout experience", as quoted by my daughter. Well done Charlie for putting this training facility together!!! Best wishes for your long-term success!! And..... thank you and your team for always have a spot for Kristin when she is in town! You all are awesome!!

My son loves C4. He’s been training here for several years. We travel from 45 minutes away because they are the best around. The staff is top notch. New facility is beautiful. If you want your child to be trained by staff who actually care and are invested in your child C4 is the place!

When you send your children to anyone wether it’s piano or fitness, you want caring and qualified people. C4 gives all that and more. C4 has programs geared to young students and old people like me. Coupled with the changing dynamic of COVID, C4 keep evolving into the best training facility in the state

We all want the same thing. Have our kids cared for, trained and coached up. C4 is the place to be. As well I highly recommend Trench Warrior for the OL/DL players in your life. Find a place with coaches and trainers who have more experience.
Our son entered as a 215 freshman and now weights 280 as a Junior. He has 15 D1 offers. We owe that success in large part to Charlie Chandler/ Austin Brown (AB) and their staff. Family

My son and a few of his youth football teammates started attending C4 last year for strength & agility training. The young men not only improved with their overall athletic performance but their overall character showed improvement. Chandler, Coach Darren, and other trainers focus on the whole person not just the athlete. I highly recommend C4 and you will not be disappointed🙂

C4 is by far the best training available for serious high school and college athletes looking to not just become bigger, faster, stronger, but also learn from the best trainers in the state. Charlie Chandler and his partner pour themselves into the young people that train there, it is incredible. I make my high school football team meet at our facility at 7:00 AM Saturday mornings in Fredericksburg, and then we caravan and drive over an hour to train in Manassas with coach Chandler and his team. We train relentlessly and what I've experienced at C4 is by far the best in the state. We get work, we get better, we get smarter, and we get coached up at a level you will not find anywhere else. C4 gets my highest recommendation.

My 2 boys have been going to C4 since it opened. Results have been phenomenal. My oldest started when he was 16 and gained 20 pounds and is a lot stronger and more physical. My youngest started at 12 he is 14 now, and the results are tremendous. Recommend for any athlete especially football. Don’t wait until they are 16 though that is my biggest regret, and why I started my younger son early.

The team at C4 are highly educated and dedicated to the development of athletes at the highest level. Their commitment to safe training techniques and personalized teaching creates an atmosphere that will challenge any level of athlete. Their track record building next level athletes from multiple sports and disciplines is unmatched. The elite performance training facility in the area.

I enrolled my 13 year old son in C4 to work on his strength and agility in the offseason (football). The training staff was OUTSTANDING. They didn't just "throw" workouts at the kids to do, but ensured they were educated on the "why" behind everything. Moreover, they ensured proper mechanics on key lifts while also pushing the kids to their potential with regard to intensity, weight, etc. I would highly recommend C4 to anyone looking to help their young athlete develop strength, speed, agility and most importantly, character.

I have been a part of the C4 family since September when I initially signed up for a 6 week challange. I have been to different gyms and training facilities but am so grateful I found C4. The time and care that Charlie and Tracy put into creating each workout and then coaching and encouraging you through it, is second to none. I have seen huge changes in my strength and abilities since starting. I enjoy the workouts and the family atmosphere at C4 and would highly recommend to others!!

C4 Explosive Sports Training is what I think about when I think of the perfect gym! This gym has a nice balance between circuit, cross fit style and weights. They offer organized classes and will tailor the class to suit your needs, wants or injuries. The group workouts are tailored to make it personal, yet challenging. One of the best things about this gym is the trainer...he's super energetic and motivating. I felt right at home and welcomed. I'm excited to workout each and everyday and haven't missed a session yet. There is simply no better place to exercise!

If you're in the area and looking for a place to train, I highly recommend C4 Explosive Sports Training!
