About
Transform Your Body Through Strength at Just B Coz Fitness Tired of chasing the scale? Let’s focus on what actually drives results—building real strength. At Just B Coz Fitness, I help adults develop stronger, leaner, more resilient bodies through structured strength training that delivers visible, lasting change. Strength training creates a leaner, more toned physique, and most clients notice changes in how their clothes fit and how they feel after 4-6 weeks of consistent training. As you get stronger, confidence improves, energy increases, and everyday life simply feels easier. When you’re stronger, everything improves. Training is done in a semi-private setting (1–3 people per session) with every workout customized for each participant. You receive individualized coaching and personalized strength programming without the cost of one-on-one training. All sessions take place at MPG Fitness in Aurora, IL, so an active MPG Fitness membership is required. Your membership provides 24/7 access to a professional, fully equipped facility that supports safe, effective strength training. If you’re looking for personalized coaching, scientifically backed programming, and a results-driven environment, reach to me for information on getting started. Let’s build strength—and everything that comes with it. Be Strong, Coach Brandon

I’m currently in my third week working with Brandon and would definitely recommend him as a personal trainer! I appreciate his attention to proper technique and lifting form. Sessions are very organized and set-up so you know exactly what to expect. He keeps track of your progress, which has been very motivating to see visually how I’ve progressed even in such a short amount of time. I don’t feel rushed at all and the pace of each class has been great! I’m looking forward to reaching new goals and getting stronger!

I joined Just Be  Coz October 10 with Coach Brandon.  Upon my arrival, he was ready to start training with an exercise routine already planned. I'm impressed by his communication and how he monitors our progress. He pushes me to keep going and to not give up. If you're serious about your health & fitness journey, I would definitely recommend Coach Brandon at Just Be Coz as your personal trainer.

I’ve been training with Brandon at Just B Coz Fitness for several weeks now, and I’m already seeing noticeable improvements in my strength, endurance, and overall fitness. The workouts are challenging but always tailored to my goals and current level. What really sets this place apart is the trainer’s energy, attention to form, and genuine dedication to helping you improve without pushing you past your limits in an unsafe way. He listens, motivates, and holds you accountable in a way that’s both encouraging and empowering. I’m training for a fitness test and thanks to this program, I feel more confident every week. If you’re looking for a trainer who truly cares about your progress and helps you stay consistent, I highly recommend Just B Coz Fitness.

Working with Coach Brandon has been an amazing experience. I am brand new to weightlifting but feel comfortable working with Brandon. He pays close attention to detail when instructing us, ensuring that we lift weights safely. He also takes the time to build trust, making sure everyone feels comfortable but growing our strength at the same time. On top of that, he brings great energy to the small group, creating a positive and encouraging training environment. I highly recommend Coach B.
