Biomechanical assessment and individualized movement programs to support recovery, restore movement, and develop strength and performance.

10/28/2026

You lift the dumbbell comfortably. Reach it forward, and suddenly the assignment changes.

Same weight. Different demand.

Moving the weight farther forward gives gravity more leverage about the shoulder. Moving it also asks your body to manage momentum—and then slow, change direction, and organize the return.

That is where strength connects to action.

Stability includes more than holding still. It includes controlling movement as positions and forces change.

In my latest Functional Training article, we explore leverage, dynamic stability, and Transformational Zones—the regions where loading and deceleration transition toward the next action.

From dumbbells to tennis racquets and shifting water loads, the question becomes:

Can you manage the approach, the change of direction, and what happens afterward?

You’ll also find practical examples of how changing reach, support, resistance, or pace can create a more useful training challenge.

What would you like your body to do more comfortably—and with greater confidence?

Perhaps you’re managing persistent pain, returning after an injury, feeling limited in your movement, or working toward greater strength and athletic performance.

I’m Bob Fanelli, founder of the Applied Biomechanics & Human Performance Center and president of Body By Design, Inc.

For more than 35 years, my work has centered on understanding how the body moves as a connected system—and using that understanding to help people progress.

We begin with your story, your goals, and a thorough biomechanical assessment. We explore how your feet, hips, pelvis, spine, and shoulders work together, how you accept and transfer force, and where movement limitations or compensations may influence the activity you want to regain or improve.

Those findings guide an individualized program that may combine:

• Movement restoration and support for recovery.
• Mobility, balance, and control.
• Progressive strength development.
• Preparation for the demands of your sport and daily activities.

As we work together, you also learn why particular movements are selected, how to adapt them, and how to recognize meaningful progress.

Assessment reveals possibility. Understanding guides the next step.

Explore my Substack for articles on biomechanics, recovery, strength, and human performance—connecting the science of movement to practical decisions about your body and training.

My office is at 5 Plain Avenue, New Rochelle, within Altafit.

To discuss your goals or arrange an initial assessment, email [email protected] or visit https://www.bobfanelli.com/.

We begin with what you can do today and build toward what you want to do next.

“Your glute isn’t firing.”
It’s a familiar explanation—but what does it actually tell us?
Perhaps the muscle needs more strength. Perhaps the hip lacks useful motion. Perhaps pain, balance, or coordination is changing how the body approaches the task.
Those possibilities lead to different decisions.
In this expanded refresh of an earlier article, I explore how the glutes help support the body, accept load, and organize movement—and why the foot, hip, pelvis, and trunk belong in the same conversation.
You’ll discover:
• What a strength test reveals—and what still needs investigation.
• Why feeling a muscle work doesn’t tell the whole story.
• How we can emphasize the hip while keeping the body involved.
• A practical example connecting assessment to exercise selection and progression.
Developing strength matters. Helping the body use that strength gives it somewhere meaningful to go.

You lifted it. But can you turn with it—and put it down?

A planter. A laundry basket. A bag of groceries.

The weight is only part of the question. Where you reach, how you shift, how quickly you move, and where the object needs to go all change what your body must manage.

Your back participates in the whole event. So do your feet, hips, pelvis, trunk, and arms.

In the final article of my lumbar spine series, we explore how to prepare those relationships for bending, turning, slowing down, and changing direction—from the garden to the golf course.

You don’t have to consider yourself an exerciser for this to matter. Life already asks these questions.

Life Moves in Every Direction. Can Your Back Share the Load?

What activity would you like to approach with greater confidence?

10/14/2026

You can hold a plank. But what must your core help you do when the rest of your body moves?
Reach overhead. Carry groceries. Turn toward the back seat. Complete a golf swing.
Abdominal strength matters. These activities also ask your hips, pelvis, upper back, shoulders, and feet to contribute—and your trunk to manage the changing demand.
In Part Two of The Lumbar Spine in Context, I explore how we develop those movement resources, learn to control them, and connect them to the activities that matter.
Even the same grocery bag asks a different question when you carry it beside you, lift it, or reach it onto a counter.
Your Back Needs More Than a Strong Core
What must that strength help you manage?

Pronation is not the problem.

Pronation is one of the ways the foot adapts to the ground, accepts force, and contributes to the Chain Reaction® moving through the ankle, knee, hip, pelvis, and trunk.

The problem may be that pronation is:
• insufficient
• excessive
• too rapid
• poorly timed
• inadequately controlled
• or never effectively transformed into propulsion

A foot that cannot become mobile enough to adapt may struggle to become stable enough to propel.

That distinction matters.

When we automatically label pronation as dysfunctional—or attempt to prevent it without understanding the individual—we may restrict a motion the body requires for shock absorption, sensory input, and whole-body movement.

The better question is not simply:

Does the foot pronate?

It is:
Can the foot access the motion it needs, control that motion, and transform it into the next phase of movement?

In my newest article, I explore pronation, calcaneal eversion, force management, and why the foot should be understood as an adaptable part of an integrated human system—not merely a rigid foundation.

A muscle does not decide its role in isolation.

Its function changes according to the person, the position of the body, the task being performed, the forces being managed, and the environment in which movement occurs.

That means the glutes do not always simply “extend the hip.” The abdominals do not function only by bracing. A muscle labeled an agonist in one movement may help decelerate, stabilize, redirect, or transfer force during another.

Muscles participate in coordinated, task-dependent relationships—responding to sensory information and working across the body’s entire Chain Reaction®.

Structural anatomy gives us an essential map. But the map is not the movement.

In the newest article in my Human Adaptation series, I explore:
• Why muscle function is context-dependent
• How muscles work through adaptable synergies
• Why a muscle can influence joints it does not cross
• What this changes about “activation” and isolation-based coaching
• How principles can guide better exercise strategies and techniques

Something new is being built at AltaFit.

Not a replacement. Not a reinvention. An expansion.

We are bringing applied biomechanics, movement assessment, and human-performance education into an already strong environment of coaching, strength, conditioning, and community.

We build upon what works—and create new opportunities to understand what may be possible.
