McCormick Health & Performance

13/03/2026

Over the past two decades, my work has evolved quite a bit.

What began as strength training and nutrition coaching gradually became something more integrated — helping clients structure their health in a way that supports demanding careers, families, and full lives.

Along the way, one pattern became clear.

Most people aren’t struggling because they lack discipline or information.

They’re struggling because the pieces of their health—training, nutrition, recovery, and lifestyle — are not working together.

That insight shaped the next chapter of my work.

I’m excited to share the evolution of my practice into McCormick Health & Performance, a private coaching practice focused on building integrated health systems for busy professionals.

The foundation is still strength training, but the work brings together physiology, nutrition strategy, recovery, and lifestyle design into one cohesive system.

Health should support your life — not become another job.

Been talking a lot this week with clients on removing the stress from one meal by making it simple, balanced, and THE SAME... Variety and creativity is great, but IMO, sometimes that adds more stress and it’s more important to get the macros balanced, remove the stress, and know that you’re getting proper fuel for your brain and body.
_____
I haven’t met anyone that doesn’t enjoy finding more ease and more balance, myself included. Here’s my go-to. Every. Single. Morning. High in protein and fiber, balanced in carbs and fat, satiating, and takes less than 5 minutes to make. Give it a go and let me know how happy this makes you 😉
_____
•35g clean grass-fed whey protein (or other protein of choice - comment below if you need recs)
•2 huge handfuls spinach
•1 medium banana (stop being afraid of carbs - your body needs them)
•1 c frozen strawberries
•1 Tbsp flax seeds
•1 Tbsp peanut butter
•8oz water
(In total this gives me 45g protein, 46g carbs, 16g fat, 10g fiber, and 500cals 👊🏻)

Kicking the boot today // Last workout in this dang thing. And so excited about it. Pedaling away on a stationary bike when all I want is to be outside on one of my actual bikes is frustrating, yet liberating.
_____
To drip sweat, to feel my blood pump, to feel capable despite an injury...is empowering. And makes you want to do more of it.
_____
I hit a slump in 2020. When covid hit, I stopped seeing my own trainer and focused primarily on keeping my clients focused and healthy. Add surgery on top of it and it’ll leave a girl feeling blah.
_____
I’m so ready for you 2021. ✌🏻

Not all health care practitioners are created equal. Do your research. Get the third opinion. Find professionals that prioritize your health over their own profit and set you up for success. Find specialists that strengthen and empower you and help you navigate your health without having to rely on them. 
_____
Earlier this week, I reached out to a new client’s chiropractor to align on our programming - I was extremely disappointed to hear his “diagnosis” and follow-up recommendations and frustrated in our health care system.
_____
This doctor diagnosed my client as having hyperlordosis - an excessive curvature of his lumbar spine (*note: this is the opposite of my assessment)
His treatment recommendation:
-come in for spinal adjustments 3x per week for at least a few months
-“tuck the pelvis" and “avoid arching the back”
-"crunches, glute bridges, and leg extensions"
🤯🤯🤯🤯
Wuttttttttt. Run client, do not walk.
_____
Any professional who instills fear in movement and doesn't focus on empowering you to strengthen and control your body through active inputs is NOT helping you correct any underlying issues. And recommendations like this may actually be causing you more harm.
_____
Sure, adjustments can relieve pressure, shift your body into a more optimal position, and create clearer communication between your central nervous system and the rest of your body. BUT, changes from adjustments are short-lived and it’s important they are coupled with active work to make those changes stick. Ever wonder why a day or so later you feel like you neeeeed to go back?
_____
Your brain, nervous system, and musculoskeletal system need active and consistent input to change and hold strength and control in any newly acquired position.

**Please, if you need a recommendation for a health professional in your area, I am happy to do some research for you. Your health and longevity depend on it. Don’t settle for anything less than the best.

Brain + Body Communication.⁠⠀
_____⁠
Question : are you someone that consistently feels tight in one particular area of your body? Or many areas for that matter? Let’s take the hip flexors for example. If your hip flexors tend to feel particularly tight you might think “man, I really need to stretch my hip flexors”. On the contrary, while passive stretching can be very beneficial in gaining flexibility (as it’s the prerequisite to mobility and controlled movement), you most likely need to also be spend time gaining control and strength in this area. How do we do that? Create a stronger communication path between your brain and your “tight spots”.
_____
Your movement restrictions are caused by the organ that allows you to produce movement in the first place: your BRAIN.⁠⠀
_____⁠⠀
When your brain isn't comfortable with a particular movement or range of motion (ie: you can't control it), it will limit your access to it by creating tension in your tissues in order to create stability. In other words, you'll feel tight in a particular area because your brain doesn't trust your movement there.
_____⁠⠀
Wherever you are on the spectrum, teach your body to control your movements through consistent and ACTIVE inputs which start a feedback loop between your tissues, nervous system, and brain.⁠⠀
_____⁠⠀
• Learn to breathe properly with diaphragmatic breathing (see video on youtube channel) to signal to your brain that you are safe and calm as you move as well as to shift from a sympathetic to parasympathetic state.⁠⠀
• Use controlled breathing during your passive stretching if you’re needing to gain more range of motion.
• Provide that new range of motion with active and controlled inputs at a similar intensity and approach to strength training (reps, sets, time under tension, rest)
• Consistency is key to training the brain

Ever wonder why some people are able to get their bodies into positions like this and yet, it feels physically impossible for you?
_____
I’ll be honest … while this is me, I can't even come close to this shape anymore, nor do I have the desire to. At this particular time in my life I was pushing to create more and more space in my body. Space and range of motion that is beyond what is considered “functional”.
_____
Additionally, there were so many factors at play that allowed me to do this pose in the first place. I was practicing for 90 minutes a day 7 days a week, I had just finished a teacher training and thought that being able to do the fancy poses made me a good teacher so I always pushed for more, I grew up forcing my hips, pelvis, and spine into splits and scorpions as a competitive cheerleader, I have a long torso, and I'm genetically hypermobile.
_____
Working to create shapes like this with my body without coupling them with the strength and control I needed led to numerous injuries that are now showing up a decade later.
_____
Point being, it feels really good to stretch and move your body in ways you didn’t think it was capable of and to create really fun shapes in the moment. BUT, it’s EQUALLY important to gain the strength and control to accompany any and all ranges of motion so you can be full functional for the long haul. And if you can’t or won't do that, is doing a pose like this really worth it? Ego check.
_____
Grateful for all the yoga teachers out there that are jumping on the train and teaching students how to . It's only weird until it's not.

Always grateful for really great conversations with other coaches. Sat down with recently, who has a deep understanding and appreciation for connecting the body and mind for peak performance.
_____
A few of my favorite highlights:
•structured variability and how to change up your routine
•mitigating injury, creating longevity in joints, and how to ride a Peloton properly
•”Cautious Carl’s” and “Logical Linda’s”
•my involuntary reaction to the name Running With Forks 🤣 and which gun I’m going to use on my first hunt

The best posture is the one that changes - frequently. How long have you been in the position you’re in right now?⁠
_____⁠
Staying in any one position for extended periods of time forces our muscles, ligaments, and nervous system to experience abnormal loading and stress by overworking to sustain tension in order to maintain the position. Over time, this has the potential lead to structural changes, pain, tightness, weakness, and degeneration.⁠
_____⁠
Every time we move (or don't move) we’re sending signals to our nervous system and brain on what we need and don't need and are creating new motor skill memories, further etching specific patterns into our tissues with each repetition. You know that old adage "use it or lose it"? This is the process of neuroplasticity (the brain’s ability to be molded), and can work for you, or against you. This is also true if you avoid certain postures or positions. Fear of slouching, twisting, or picking something up with anything other than a "neutral spine"? Your brain will begin to recognize that it doesn’t need that movement anymore and signal the body to respond accordingly. Remember, there are no bad postures, only prolonged positions.⁠
_____⁠
Unfortunately, we live in a world where many people are required to stay in one position for their jobs which is why we see so many “tight" hip flexors and hamstrings, back pain, and poor breathing mechanics. ⁠
_____⁠
If this is you, the best thing you can do is to perform stretches that move in the opposite direction of any prolonged position and stay as active as you can outside of work to keep your muscles strong and joints mobile.⁠
