The NICS Training Principle: A Comprehensive Guide to Smarter, Customized Training

By Nic (aka @ThiccNic)

Welcome to the NICS Training Principle—a guide that embodies my approach to fitness, training, and personal growth. After 18 years of working out and coaching (I’m 31 now), I’ve learned that fitness is not about fitting into a box or following a one-size-fits-all approach. It’s about adaptability, learning, and finding what works for you and your unique goals.

This guide is here to educate, inspire, and help you create a sustainable, effective training plan. Whether you’re a beginner, an experienced lifter, or a coach looking to refine your methods, there’s something here for everyone.

The Core Philosophy: Everything Works, But Nothing Works Forever

One of the most important lessons I’ve learned is that every training style, modality, and approach has value—but no single method will work forever. The human body is incredibly adaptive, and while that’s a good thing, it also means that sticking to the same routine for too long will eventually lead to stagnation.

Unless you’re training to compete in a specific sport or discipline, specialization can actually limit your growth. For most people, being a “jack of all trades” is the best approach. This doesn’t mean you should dabble aimlessly—it means you should explore, experiment, and integrate different styles into your training.

Key Takeaways:

• Try new things and learn: Don’t be afraid to step outside your comfort zone. Experiment with different training styles, tools, and techniques. Ask yourself, “How can I apply this to myself and others?”

• Have a game plan: Whether it’s a general framework or a specific program, having a plan is essential. Without one, you’re planning to fail.

• Stick to a program long enough to see results: Consistency is key. A good rule of thumb is to follow a program for 2-6 weeks and set general goals for 6-12 weeks.

• Avoid plateaus by cycling your training: While “muscle confusion” is a myth, breaking up your training cycles can help you avoid stagnation. For example:

  • 12 weeks of hypertrophy training

  • 2 weeks of mobility and isometrics

  • Another 12 weeks of hypertrophy

  • Or, cycle into a 6-12 week strength phase to complement your hypertrophy work.

The key is to keep things fresh while still maintaining structure.

Fitness Is a Spectrum

Fitness isn’t black and white—it’s a spectrum. Everything in fitness can complement everything else, but some modalities have bigger carryovers than others. For example, strength training has a foundational role because it builds the base for almost every other physical quality: power, endurance, mobility, and even aesthetics.

Training Tips:

• Strength is the foundation: Progressive overload should be the cornerstone of your training. Whether your goal is to build muscle, improve athletic performance, or just feel better, getting stronger will help you get there.

• Rest is essential: Recovery is where the magic happens. If you’re working out 1-4 times a week, you’re likely getting enough rest. If you’re training 4-7 times a week, you need to undulate intensity—alternate between high-intensity and lower-intensity sessions to avoid burnout.

• The 80/20 rule: Train for the long term 80% of the time. This means focusing on sustainable, consistent progress. The other 20% can be short-term bursts of intensity or experimentation.

• Fitness is an infinite game: The goal isn’t to “win” the workout—it’s to keep working out. Something is always better than nothing.

Keep It Simple, But Do It Well

One of the biggest mistakes people make is overcomplicating their training. Fancy exercises, overly complex routines, and gimmicky programs might look cool, but they’re rarely effective. The truth is, simple, well-executed movements will always outperform overly complicated ones.

Prioritize Quality:

• Form is king: Quality of movement and form should always come first. If you get hurt, you can’t train—and if you can’t train, you can’t progress.

• Foundational lifts are non-negotiable: Your programming should always include the basics:

  • Squat

  • Lunge

  • Hinge

  • Row (horizontal and vertical)

  • Press (horizontal and vertical)

  • Plank, carry, and rotate

• Progression is key: Over time, you can change the positions, patterns, and priorities of these lifts. A squat is always a squat, but there are infinite ways to load it, adjust tempo, or change its effect.

Reps, Sets, Tempo, and Rest

These variables are the building blocks of your training. They determine the outcome of your program, whether it’s strength, hypertrophy, endurance, or mobility.

Pro Tips:

• Learn the basics first: Understand how reps, sets, tempo, and rest affect your results. For example:

  • Lower reps (1-6) with heavier weights build strength.

  • Moderate reps (6-12) with moderate weights build hypertrophy.

  • Higher reps (12-20+) with lighter weights build muscular endurance.

• Rest matters more than you think: Especially during strength training, don’t skimp on rest between sets. Your body needs time to recover so you can lift heavy and perform at your best.

• Strength > HIIT: While HIIT has its place, strength training should be your priority. You need rest to lift heavy and build a solid foundation.

Be a Student of the Game

Fitness is constantly evolving, and there’s always something new to learn. But that doesn’t mean you should ignore the basics or dismiss old-school methods. Some of the most effective training techniques are the ones that have stood the test of time.

Movement Patterns Over Muscle Groups

Don’t think of the body as isolated muscle groups. Instead, focus on movement patterns. For example:

• A squat works your legs, but depending on how you load it, it can emphasize quads, glutes, or even core and upper back isometrics.

• This is where the 3 Ps—Position, Pattern, and Priority—come into play.

Splits and Programming

Your training split should align with your goals, training age, and recovery capacity. Here’s a breakdown of different splits and who they’re best for:

• Full-body splits: Great for beginners or those with limited time.

• Upper/lower splits or push/pull splits: Ideal for intermediate to advanced lifters who want to increase training frequency.

• Bro splits (e.g., chest day, back day): May not work for most people due to the need for higher frequency and volume.

The Importance of Rest and Recovery

Your body doesn’t get stronger during your workouts—it gets stronger during recovery. If you’re constantly pushing yourself without giving your body time to recover, you’re setting yourself up for burnout, injury, and stagnation.

Recovery Tips:

• Sleep is non-negotiable: Aim for 7-9 hours of quality sleep per night.

• Active recovery: Incorporate low-intensity activities like walking, yoga, or mobility work on your rest days.

• Nutrition matters: Fuel your body with the nutrients it needs to recover and perform.

Final Thoughts

Fitness is a journey, not a destination. The goal is to keep moving, learning, and growing. Whether you’re training for aesthetics, performance, or just to feel good, the NICS Training Principle is about finding balance, staying consistent, and always being a student of the game.

Remember:

• Everything works, but nothing works forever.

• Strength is the foundation.

• Quality over quantity.

• Fitness is an infinite game—keep playing.
