🚨 Motivation Monday🚨 “The happiness of your life depends on the quality of your thoughts.” - “The Meditations”, Marcus Aurelius Your thoughts shape your actions. What you believe, you become. If you constantly tell yourself that you “can’t” or it’s “too hard,” guess what? That’s the reality you’ll create. But if you start controlling those thoughts and choosing ones that empower you, your actions—and your results—will follow. 💥 How does this play out in the gym? You can approach every lift, every set, and every challenge with the mindset of possibility and progress. A tough workout is another opportunity to apply yourself to a challenge; to learn, to grow, and to get stronger. This mentality applies to all aspects of life. When you train your MIND like you train your body, you can begin approaching your life with a different narrative. You start to see obstacles as possibilities instead of limits. Happiness, progress, and success all start with the way you think. 💪🧠 Ask yourself: How can you choose better thoughts today? How can you take control of your mentality to make progress in the gym and in your life? 👊 COMMENT below one positive thought you’re focusing on today, and let’s level up our mindsets together. 💯 #MotivationMonday #MentalStrength #MindsetMatters #ThoughtsBecomeThings #Positivity #Progress #CKStrength #MindsetShift #GymMotivation #MentalToughness #PositiveThinking #TucsonPersonalTrainer #PersonalGrowth #FitnessJourney #GymLife #TucsonAZ #AZFitness #SelfImprovement #MindOverMatter #MindAndBody #MentalityIsEverything #FYP #StrengthGoals #EmpoweredMindset #WellnessJourney

🚀 Motivation Monday 🚀 “The way to get started is to quit talking and begin doing.” - Walt Disney Whatever your goal is, whether it’s fat loss, muscle gain, conquering a long-term goal, or leveling up your career, it all starts with one thing: taking action. 💥 It’s easy to talk about your goals, plan, and dream big, but without doing, it stays just that—a dream. The hardest part is getting started. Let’s face it, waiting for the “perfect time” or “ideal moment” is just a way to avoid taking that first step. The truth is, progress doesn’t need to be perfect; it just needs to be consistent. Whether it’s hitting that first workout, dialing in on your nutrition, or knocking out that one task today, every action fuels the next. That’s what we call activation energy, the initial action that kicks off the whole reaction. Mentally, it’s the hardest part, but once you start moving, you can create momentum that builds exponentially, fueling progress and allowing you to achieve more than you could have ever initially imagined. 🚀🔥 Quit talking. Start doing. Make TODAY the day you take that first step. Don’t wait until it “feels right” - make it the right time to happen 💯 What’s one thing you’re going to do TODAY to move closer to your goals? Drop it in the comments and let’s hold each other accountable! 👊👇 Need HELP getting started??

Understand EXERCISE VARIATION to make PROGRESS! Example A: LUNGES I’m often asked by clients whether they *should* perform lunges with more forward knee bend (like a squat), or with a less-knee bend (~90*, wider step). Truth is BOTH are fine variations, with slight differences. A knee-forward lunge is usually more QUAD LIMITING. This variation can be a little better for finishing your quads on a leg workout, or targeting your knee extension strength to apply to a bigger movement like Squats. It does still work your glutes and adductors, you’ll just 🔥FEEL🔥your quads. The 90-degree knee lunge is more GLUTE 🍑 and ADDUCTOR FOCUSED. This variation uses a wider step, putting your glutes under more tension, and adductors (groin) through more stretch. This variation will only work quads a tiny bit, which makes sense, since this is essentially the same position for your leg as a wide stance squat 🏋🏻 Example B: CURLS 💪🏼💪🏼💪🏼 I am often asked whether a client should perform a curl with their elbows stationary at their sides, or if their elbows should move. BOTH are just fine variations! Keeping your elbows PINNED and stationary creates what I call the STRICT CURL. This variation places ALL the tension and leverage on the BICEPS, since the only joint flexing is your ELBOW. This is GREAT to learn the fundamentals of targeting biceps, but can be hard to balance when performed HEAVY. For some people, it is very hard to feel the peak contraction AKA the SQUEEZE, since it is very hard to bend your elbow all the way. In the “Elbows-UP” variation, you’ll simply perform a normal curl, and when your elbows begin to stop bending, you bring the weight UP to your FACE or NECK to essentially FLEX 💪🏼💪🏼💪🏼 on the last 2-3 inches of ROM. This variation can be SUPER easy to load and balance when heavy, and allows for a MASSIVE eccentric load. With ANY exercise variation, simply pick 1 variation to work on each workout. Progress that SAME VARIATION for 5-6 weeks. Change the variation every so often to revitalize your training. #tucsonpersonaltrainer #personaltrainer #AZ #tucsonaz #fyp #biceps #legday #hypertrophy #physique

Client Success Stories

Christian is the best personal trainer, and that's an understatement. He not only cares about your fitness goals, but cares about you as a person. I have him as an online coach for powerlifting and just this last July I placed first at my first meet, the state games. This guy knows his stuff.

I can't say enough about Christian! I initially started training with him to improve injuries that I sustained training jiu jitsu, and to build strength that would benefit me in returning to grappling. His understanding of programming has blown me away and I've seen noticeable improvements in each phase/program. My injuries are significantly more manageable, my strength has increased tremendously, and I have been able to return to jiujitsu. The coaching, support, and motivation I've received have helped me be dedicated to training and excited about my progress and potential. I would absolutely recommend Christian if you're looking for assistance reaching your goals.
