I don’t care how good you are at 15 or 16 years old‼️

Can you measure up with the big dogs in college at 18⁉️

Because if not, that transfer portal has plenty of guys that are PHYSICALLY ready 🤷🏻‍♂️

Don’t be the guy with the “Would’ve, Could’ve, Should’ve” all the time 🤦🏻‍♂️

OVERWORKED & UNDERDEVELOPED 🤦🏻‍♂️

As parents and coaches, we HAVE TO DO BETTER‼️

These kids are playing too many games‼️

Not getting enough rest / sleep‼️

They eat like birds & their diet lacks substance‼️

Scared to hit the gym consistently and lack the discipline to follow a legit program‼️

Skip the development stage altogether and end up injured at some point‼️

Never have a true OFFSEASON to focus on Strength, Power, Speed & Resiliency‼️

We have to get these kids back to the basics 📈

There is so much more to Performance Training than “Maxing Out” on Bench, Squat & Deadlift at your school every day 🤦🏻‍♂️

Movement Quality & Efficiency is the 🔑

Being Strong is GREAT‼️ But it doesn’t matter if you can’t produce force and you run like a giraffe 🤷🏻‍♂️

For all of you that are new to following the KTS page:

My name is Nate Keller (Coach Keller) 👋🏼

Husband, Father of 4, Follower of Christ and Owner of Keller Training Systems, LLC. 🐺

God blessed me with the ability to play football from age 4 to 29 years of age. I was able to play professionally for 6 seasons not solely due to talent but also from the drive and willingness to OUTWORK EVERYONE‼️

I’ve been a lifelong student of health, fitness, strength & conditioning and sports performance which ultimately led me to my 2nd career in the Strength & Conditioning industry 📈

I’ve trained 1000s of athletes and every day adults since establishing KTS in 2013 💪🏼

I’ve helped 1000s of athletes obtain scholarships to college and earn professional contracts as well as helped athletes recover from injuries 📈

I live by:

Discipline, Consistency, Hard Work, Grit, Determination and the Ability to Adapt & Overcome‼️

I’m more than a Coach‼️

I’m a Mentor, a Leader, a Father Figure and the person who’ll tell you what you need to hear more than what you want to hear 🤷🏻‍♂️

I don’t accept:

LAZINESS
EXCUSES
INCONSISTENCY
AVERAGE
MEDIOCRITY

The STANDARD is the STANDARD‼️

If you’re ready to be the best Athlete & version of YOURSELF, look no further‼️

Welcome to KTS 🐺📈
