Key Takeaways
- Your body runs like an engine. Some engines want race fuel. Some want diesel. Put in the wrong fuel and the engine stalls.
- There are 5 types of engines. We call them neurotypes. Type 1A, 1B, 2A, 2B, and 3.
- Most guys over 35 have been running the wrong fuel for years. That's why old programs stopped working.
What Is Neurotype Training?
Every engine has a redline.
Push a diesel truck engine like a race car and it won't go faster. It will break.
Your body has a redline too. Your brain and nerves control how much training you can handle. Some people can lift heavy all day. Some people burn out fast on heavy weight but can do endless reps. Some people need a strict plan or they fall apart.
This is called your neurotype. It's not a personality test. It's a training map.
There are 5 neurotypes. Once you know yours, you stop guessing. You train the engine you actually have — not the one your buddy has, not the one on Instagram.
Who This Is For
You're 35, 45, 55. You did CrossFit. You tried your friend's program. You followed some guy online.
None of it stuck. Or worse — it hurt you. A shoulder. A knee. Your back.
You're not broken. You're not "just old." You've been running the wrong fuel in your engine. This page shows you how to find the right one.
Where This Comes From
A doctor named Robert Cloninger studied how brain chemicals shape behavior back in the 1990s.
A strength coach named Christian Thibaudeau took that research and built it into a training system. He matched training style to brain type. That system is what you're reading now.
At Boltz Performance we add one more piece most people skip: your hormones change your engine as you get older. A 25-year-old 1A and a 48-year-old 1A are the same engine — but the fuel supply changed. That's why we always pair neurotype with bloodwork inside Boltz Performance Coaching. Your type tells us how you're wired. Your bloodwork tells us what your body can actually do with that wiring right now.
The Five Neurotypes
Type 1A — The Intensity Seeker
One word: Intensity The line: "I get bigger by getting stronger."
Who you are: Competitive. Loud. You want the heaviest plate on the bar and you don't care who's watching. You're a grinder. You can push a heavy weight even when it looks stuck.
What this means for training: You run on heavy weight, not lots of reps. Your engine burns out fast if the session runs too long. Keep it under 40 minutes.
Do this:
- Heavy weight, low reps
- Big pauses at the bottom of a lift
- Dead-stop starts (like a pin press)
Skip this:
- High-rep "burn" sets
- Jump training
- Long sessions
The mistake we see after 35: Guys keep adding more sets because "that's what the plan said." Your nervous system can't recover from that much heavy work. Less volume, same weight, better results.
Type 1B — The Explosive Athlete
One word: Explosiveness The line: "I get bigger by moving fast."
Who you are: A multitasker. You get bored fast. You move weight with speed, not grinding. You like switching between exercises.
What this means for training: You need speed. Slow, grinding reps kill your performance. Pairing two exercises back to back (like a bicep curl, then a tricep push) keeps your brain switched on.
Do this:
- Jump training
- Fast, explosive reps
- Pairs of exercises (A1, then A2)
Skip this:
- Slow tempo reps
- Grinding through a stuck rep
- One long, boring set after another
The mistake we see after 35: Guys slow down their training because they think "slow and controlled" is safer as you age. For a 1B, that kills your results. You still need speed — just smarter speed, with better warm-ups.
Type 2A — The Chameleon
One word: Variation The line: "Everything works. Nothing works for long."
Who you are: Right in the middle. Half heavy-lifter, half bodybuilder. You get bored doing the same thing. You need a mix.
What this means for training: You handle the most total training volume of any type — but only if you mix heavy work and pump work in the same session. New tools (chains, bands, different bars) keep you motivated.
Do this:
- Heavy lift, then lighter pump work, same session
- New equipment often
- Regular program changes
Skip this:
- Months of the exact same program
- Only heavy work, or only pump work
The mistake we see after 35: Guys stick with one style for too long because "consistency is king." For a 2A, sameness is the problem. You need planned variety, not chaos.
Type 2B — The Sensation Seeker
One word: Sensation The line: "I get stronger by getting bigger."
Who you are: You train by feel. You want to feel the muscle working — the pump. You're emotional about your training. You get stronger as a side effect of building muscle, not the other way around.
What this means for training: You recover fast from lots of reps but burn out on heavy, max-effort lifting. Bodybuilding-style training is your best friend.
Do this:
- Higher reps (6+)
- Supersets and dropsets
- Lighter weight, more volume
Skip this:
- Very heavy weight for long stretches
- Low reps as your main diet
The mistake we see after 35: Guys chase heavy numbers because that's what "real training" looks like online. For a 2B, that's the wrong fuel. Build the muscle. Strength follows.
Type 3 — The Controller
One word: Control The line: "Building muscle is about controlling stress."
Who you are: You didn't grow up loving the gym. You like routine. Surprises stress you out. You want to feel in control of every rep.
What this means for training: You need a plan and you need to stick to it. Long warm-ups matter — they calm your nervous system before the real work starts. Slow, controlled reps work best.
Do this:
- Same core exercises for a long stretch
- Long, thorough warm-ups
- Slow tempo, pauses
Skip this:
- Constant program changes
- Rushed warm-ups
- Hype-yourself-up lifting
The mistake we see after 35: Guys jump program to program chasing "the next best thing." For a Type 3, that's the actual cause of their stall. Pick a plan. Stay on it. Let your body trust it.

| 1B | Explosiveness | 3-6 reps, fast | Moderate |
| 2A | Variation | Mixed | High (mixed styles) |
| 2B | Sensation | 8-15+ reps | High |
| 3 | Control | Moderate, slow tempo | Structured |
Frequently Asked Questions
What is my neurotype? It's the way your brain and nerves respond to training. It tells you how much weight, how many reps, and how much rest your body actually wants.
Can I be more than one type? Yes. Most people are a mix, leaning toward one type. A quiz gives you a starting point. It's not the full picture.
Does my neurotype change as I get older? Your wiring stays the same. But your hormones change what that wiring can do. That's why a plan that worked at 28 can stop working at 45 — even if your type never changed.
How is this different from a personality test? A personality test tells you how you act with people. This tells you how your body reacts to training stress. Two different things.
The Short Version: 3 Athlete Types
Five engines is accurate. It's also a lot to hold in your head.
So inside our Neurobuild coaching, we group those five engines into three bigger drivers — the actual force behind the fuel:
- The Challenger — Types 1A and 1B. Reward-driven, stimulus-hungry. You need a visible target, not just a plan.
- The Guardian — Types 2A and 2B. Even-keeled day to day, but the power shows up when the stakes are real.
- The Storm — Type 3. A powerful engine that struggles to downshift. Bloodwork's clean, but you feel wired and tired.
Same wiring underneath. Just an easier way to remember which fuel your engine needs.
