Fuel for Functional Athletes Chasing PBs
In HYROX® and CrossFit® training, progress comes from small changes, repeated consistently. Your sports nutrition should work the same way.
You Already Know the Basics
When you train for HYROX and CrossFit, you learn these quickly: eat a balanced diet, stay hydrated, fuel your workouts, and recover between sessions.
It sounds simple, but the hard part is doing those things consistently when:
Volume and intensity increase
Recovery doesn't keep up
Life gets busy outside training
In these situations, it's easy for nutrition to become reactive.
Building a “system” that proactively accounts for the setbacks, and keeps you on track, will set you up to achieve your athletic ambition quicker.
This is how we think about sports nutrition. No hype, no fads. Just small, evidence-backed adjustments that lead to big results.
Small, Consistent Inputs that Compound Over Time
We design sports nutrition as a system to support the work you repeat, not just the all-out sessions, fitness races, or functional fitness competitions.
Ingredients rooted in research
Each must have a pattern of evidence showing it will help improve your athletic performance.
The right dose at the right time
Consistent daily or strategic use adds up to real, measurable progress in your training.
Built for how athletes actually train
Real-world training is never perfect, so your sports nutrition needs to be reliable.
Where the Blonyx System Meets Your Training
We’ve all been there. Legs lit up. You can't catch your breath after a run. But the workout isn’t done. You still have to pick up the wall ball, cycle the barbell, or get back on the SkiErg.
What Helps in These Moments
Beta-alanine: Taken daily, beta-alanine increases your ability to buffer muscle burn, helping you hold pace through lunges, burpees, and long SkiErg intervals when fatigue spikes.
Carbohydrates: High-intensity intervals burn through glycogen quickly. Strategic carbohydrate intake helps maintain output across long metcons and hybrid sessions.
Nitrates (400mg from beet juice): Nitrates from a high-concentration shot of beet juice taken 90 minutes before training will improve your muscle efficiency, so hard efforts feel more sustainable when your heart rate is pinned.
Zone 2 work only works if you can repeat it. That means sessions can’t be cut short by low energy, dehydration, or lingering fatigue. Small nutritional adjustments don’t replace the work, they help ensure the work actually lands.
What Helps in These Moments
Nitrates (400mg from beet juice): Support oxygen efficiency and muscle economy, helping steady runs, row intervals, or mixed-engine sessions feel more controlled with the same perceived effort.
Electrolytes: Help move water into the body more effectively, supporting hydration status during longer or warmer sessions. When hydration is dialled, heart rate drift and perceived effort are easier to manage.
Carbohydrates (drinks or gels): Help ensure longer aerobic sessions aren’t capped by low fuel or unexpected energy dips.
HMB: Helps reduce muscle damage during higher-volume blocks, supporting recovery so aerobic volume can stay consistent week to week.
Strength and power matter, especially when they have to be repeated under fatigue. Barbell cycling. Sandbag lunges. Sled pushes. Efforts that demand force production again and again. These efforts aren’t limited by max strength alone. They’re limited by how well you can produce force repeatedly, manage fatigue, and recover between sessions.
What Helps in These Moments
Creatine: Supports repeated high-intensity force production, helping you sustain force output across repeated efforts, not just the first heavy set.
Beta-alanine: Buffers lactic acid, allowing you to push through those final reps as fatigue and muscle burn sets in.
HMB: Daily use will support muscle integrity and prime your muscles for progress in strength and power training.
You’re not injured. You’re not wrecked. You just don’t feel quite ready. Your legs might feel heavy and sore, or the warm-up takes longer to click. Strength is there, but it takes more effort to access it. Yesterday’s work is still in your system, a sign that your body's recovery hasn’t fully caught up.
What Helps in These Moments
Protein (from real foods wherever possible): Provides the amino acids needed for muscle repair and adaptation so training stress doesn’t carry forward more than it should.
Creatine: Supports cellular energy availability and training readiness, helping strength and power feel more accessible even when sessions stack up back-to-back.
HMB: Reduces muscle damage from training and supports faster recovery, and is one of the small, daily inputs that compound over time.
Multivitamins: Covers nutritional gaps that can quietly accumulate during hard training, like an insurance policy that protects against the days you can't eat as well as you'd like.

I’ve been taking HMB+ Creatine for over a decade, and it’s a non-negotiable for me and my family. The ingredients some of the most researched and trusted there is, with experts like Dr. Andrew Huberman highlighting its cognitive benefits alongside its well-known impact on strength and recovery. Stronger muscles, sharper mind, and a body that bounces back faster? I’m all in.
I've been using Blonyx Beta Alanine, and even in the first month, I noticed less fatigue from training, much quicker recovery, and greater endurance during my sessions! Total game changer.
There are a LOT of protein powders out there, and you want to get the most from the one you choose. Hands down the best part of Egg White Protein Isolate is how easily it mixes and how clean it tastes. It doesn't feel heavy like whey protein powders do. I like that it's simple and straight to the point.
