You are totally replaceable at your coaching job. You are NOT replaceable at home. Remember that perspective when you’re thinking about “balance”.

How I program.
75% of what I do, I KNOW works.
20% of what I do, I THINK works.
5% of what I do, I have NO IDEA if it works—this is where I GUESS and EXPERIMENT—I’m not willing to invest much time or effort here.

POWERFUL: Legendary #NFL TE Greg Olsen with a beautiful message at the Miami commencement speech.
“Your pursuit of greatness… don’t forget to also be good.”
“Go live your life. Go make mistakes. Go start a business. Travel the world.”
Amazing 🙌🙌🙌

We can’t change the playing surface (turf) but we can build robust and resilient athletes with good training, which is the best “injury prevention” program you can have.
How we do it.
1. FIFA 11+ warm-up 2x/week blended into our regular warm up → 30–50%+ fewer non-contact injuries (trains deceleration + landing to beat turf’s extra grip)
2. Single-leg plyos and controlled landings (box drops, lateral hops)
3. Eccentric strength (Nordics, single-leg RDLs)

Why do they prefer grass? The 92% preference isn’t just opinion—it’s backed by NFLPA analysis of NFL injury tracking showing turf correlates with higher rates of certain lower-body injuries + plus players direct experience. 1. Non-contact lower extremity injuries: 28% higher rate on artificial turf vs. natural grass. 2. Non-contact knee injuries: 32% higher on turf. 3. Non-contact foot/ankle injuries: 69% higher on turf. 4. Injury rate: 1.22 per game on natural grass vs. 1.42 per game on artificial turf. 5. Odds of a season-ending injury requiring surgery were 60% higher on turf (odds ratio 1.60). [source NFLPA] Players consistently report their bodies feel better the next day on grass because grass feels less punishing on the body—less joint stiffness and overall wear.

Sometimes the player that NEEDS to play with max-effort in the NFL is more of a liability than an asset. The league isn’t just about effort, it’s about scalable movement. That’s the difference between being in the NFL versus belonging in the NFL.

@carvperformance Thank you for providing me with more numbers instead of just trying to argue like some folk

Fair and common critique of surface-injury studies.
This is from the official NFLPA statement by then-President J.C. Tretter:
“Based on NFL injury data collected from 2012 to 2018, not only was the contact injury rate for lower extremities higher during—“practices” and games held on artificial turf, NFL players consistently experienced a much higher rate of non-contact lower extremity injuries on turf compared to natural surfaces.”
That includes OTAs / Mini-Camps / Training Camp.
That covers the 28% higher non-contact lower-extremity rate, the 32% higher non-contact knee rate, and 69% higher foot/ankle rate.

@carvperformance If this doesn’t include the non contact injuries that happen during OTAs , Mini Camp & Training Camp which occur on grass then it is a biased study

Rueben Bain Jr. is going to be a neuromuscular and physiological nightmare for offenses on Sundays.
✅ 1. Elite RFD
✅2. Instant peak force production
✅ 3. Unblockable speed-to-power transitions
✅ 4. Explosive first step quickness
✅ 5. High Reactive Agility

You can certainly practice backpedaling on an unstable surface—for balance/coordination, rehab/return to play situations, but it’s not an effective way to develop peak Rate of Force Development (RFD) for football.
Why?
1. Energy Leakage—Much of the effort (force) is absorbed by the air-filled surface which increases ground contact time—the very opposite of what you want—decreased ground contact time, and what high-RFD training aims for.
2. Force Reduction—Research ( Behm, Anderson, and Curnew et al, 2002) shows that training on highly unstable surfaces can reduce the maximum force production of the quads by up to 70.5%. You can’t develop explosivepower if you cannot apply high levels of force.
How do you increase its effectiveness—same drill just do it on grass or turf—now you’ve increased its ability to actually transfer to the game.

Wow: Ravens star CB Chidobe Awuzie posted his unique training in preparation for this upcoming season. Awuzie is going to be a PROBLEM 😈

Two common denominators I’ve seen in every single successful elite athlete I’ve ever coached.
1. Consistent Discipline—they ground themselves in progress versus chasing perfection.
2. They Follow The Plan—not their feelings and learn how to overcome their own internal resistance.
English
Why carry uneven loads?
Because it forces unilateral power, anti-rotation core & stabilization, develops violent ground reaction force through one leg, builds grip + forearm strength/endurance, has direct sport-specific transfer.
Uneven load training is an excellent supplemental tool to your main strength work.

Old school principles, new school methods
@TOwens034, Ben Creamer, and Morris Henry of @UW_Football shared their complete football performance training system from strength to speed to return-to-play
Rooted in foundational principles like triphasic training and short-to-long speed development, tune in to hear how they use motorized resistance to not only precisely execute their programs but also iterate and improve them by using insights from the data

The KEY part of development is a player willing to work — and a coach willing to push the standard.
@HinzmanCarson continues to challenge himself & credit to coach @TylerBowen for expanding his overall skill-set & upholding the standard.

It’s not just big guys doing “hit” drills—it’s Force Production (how strong you are and Rate of Force Development (how fast can you use that strength).
It’s about the explosive power you see in those pad slams and bursts. That power transfers straight to the game, tying in speed and agility through better movement patterns. 🏴☠️
