Dr. Zac began his career working in professional sports. He noticed a large discrepancy between the quality of care that elite athletes receive when compared to the normal active public. This inspired him to create Cohen Health and Performance, a place that treats everyone as if they are a professional athlete! He graduated summa cum laude from Northeastern University in 2011 with his Doctorate in Physical Therapy, and also became a Certified Strength and Conditioning Specialist (CSCS). While at Northeastern he worked as a Physical Therapy Graduate Assistant for the New England Patriots, and served as a strength and conditioning coach for Northeastern University athletics. Prior to moving to Maryland, Zac was a Performance Physical Therapist with EXOS (formerly known as Athletes' Performance) in Dallas, TX where he treated and trained the world's most gifted athletes from throughout the NFL, MLB, NBA, MLS, and various Olympic teams.

The first drills that we teach to youth athletes

It is essential to understand the demands placed onto the body when working in a sports physical therapy, injury rehabilitation, and performance training setting.

Sports and weight training require athletes to control the body when moving rapidly.

If an athlete wishes to own the “stack” (stacking of our head, rib cage and pelvis over one another) and protect their lower back they must be capable of doing so when performing high velocity movements.

When youth athletes first train, we use medicine ball drills to teach this ability.

The medicine ball chest pass is a great drill to teach this capability. During this the drill, the athlete is generating enough velocity to propel the ball into the wall and back. As this occurs, it can be easy to lose the “stack” requiring the athlete demonstrate a higher of level of body control.

After mastering the chest pass, it is time to bring the arms overhead. More trunk strength and control are required with this movement and the ability to manage intra-abdominal pressure is further challenged. Check out this exercise here.

These are just a couple of the exercises that we incorporate into the training sessions and warmups for our youth athletes.

Is Your Doctor (or physical therapy clinic) Taking Care of You?

Recently, I joined my mother-in-law for a visit to a physician’s office.

The physician she saw has a solid reputation and is known as a “go-to” expert in his field.

During the visit he spent a total of 5 minutes with my mother-in-law, glossing over test results and providing very brief recommendations.

He appeared to be speaking as fast as he could so that he could finish the visit and to get to his next patient. After his rushed explanation, we attempted to ask questions, which he answered while backing out of the room.

Sadly, experiences like this are very common in the world of healthcare and I do not blame the healthcare providers because they oftentimes are not left with much of a choice.

The health insurance industry consistently reduces reimbursement to health care providers, forcing them to schedule more patients within a fixed time period. As a result, the quality of care suffers, and everything becomes less personalized.

This also occurs in physical therapy, forcing many clinicians to resort to “cookie cutter” protocols.

If you go to Physical Therapy because of lower back pain then you get put on the lower back pain protocol, shoulder pain=shoulder protocol, etc.

Many times, this works, however, it is not the best choice for those looking to live an active, pain free, and healthy life.

For this reason I typically seek out practitioners that are out of network with health insurance as it enables them to provide me with the highest quality of care possible. In this approach I am treated like an individual and I get to ask all the questions that I would like so that I can a better understanding of my health.

We are out of network providers here at Cohen Health and Performance. We strive to get the best possible results for our patients in the least number of visits, while also providing the education necessary to prevent future issues from occurring.

People can feel better, move better, and enjoy an active lifestyle. Our mission at CHP will always be to take the best possible care of our patients and that is why we are out of network with health insurance.

Why Are You Bench Pressing?

How often do you stop and think about how you want to perform an exercise and if that is conducive to your goals? Our physical therapy patients here in Bethesda often have the goal of learning to train without pain or discomfort. Training clients, most concerned with sports performance may have goals that include becoming stronger, faster, or building muscle mass.

There is not always a “correct” way to perform every exercise.⁣ Let’s take the bench press as an example.
⁣
Depending on your goals and capabilities, you may want to play around with the angle of your arms when bench pressing.⁣
⁣
Is your goal to build big pecs? Perform the lift with the arms closer to 90 degrees and do not allow the arms to drift past the body as you can see in the video here.
⁣
Do you want to lift more weight while keeping your shoulders and lower back healthy? If so, perform this lift with the arms closer to 45 degrees to take the stress off the front of the shoulders. Check out this bench press variation here.⁣
⁣
This is just one of many exercises that can be altered to change the focus.

The key is being clear on the outcome that you have in mind!⁣

What All Rotational Athletes Must Be Capable Of (Part 2)

The best ability is availability.

Rotational athletes come to physical therapy for help for with a variety of different overuse injuries (for more information, check out part 1 here). These injuries are the result of an excessive amount of stress placed onto one area which exceeds the body’s ability to tolerate.

Excessive stress accumulates in a particular area (often the lower back) as it is forced to pick up the slack from another area of the body that is not doing its part. Injury rehabilitation often involves discovering what these areas are.

Many times, it is the hips.

The hips are large joints with powerful muscles (ex. The glutes) surrounding them. This area should be generating the power to make things easier elsewhere.

The med ball hip toss teaches the body to generate rotational power at the hips and ultimately propel the ball through the arms. Once you have mastered this drill, step things up and give the perpendicular med ball throw a shot!

What All Rotational Athletes Must Be Capable Of

Low back pain with golf or arm pain with throwing. At our performance physical therapy practice, we see this constantly.

Swinging a golf club, throwing a baseball and hitting a tennis ball involve a great deal of rotation. Many areas of the body should be involved in these movements, however that is not always the case.

It is common to see baseball pitchers that are experiencing arm issues demonstrate the habit of trying to “arm” the ball as they throw it. There is not much contribution from the legs which places a great deal of stress on the arm and over time results in overuse injuries.

Many golfers and tennis players experience lower back pain because they do not effectively link the power that they generate in the lower body through the trunk, into the upper body and ultimately to the head of the club. As a result they compensate elsewhere, placing increased stress onto the lower back.

The rotational row is a great drill to train the body to generate rotational power through the legs and connect it through the trunk. View this exercise here.

Once you have mastered the rotational row and learned how to link the power generated in the lower body to the trunk, we can now add in the upper body! The rotational lift trains the body to generate rotational power through the legs and connect it through the trunk and arms. Check this exercise out here.

A different form of shoulder strength

Building Shoulder Strength in End Ranges: How Physical Therapy Can Prevent Injury

Many shoulder injuries that bring athletes to physical therapy are the result of overuse or instability when the shoulder reaches its end range of motion. Whether you’re lifting weights, throwing a ball, or performing overhead movements, your shoulder is vulnerable when pushed to its limits.

It’s common to assume that the solution to these issues lies in increasing flexibility through stretching and mobility drills. While flexibility is important, it’s only part of the equation. The real issue often lies in a lack of strength and stability when the shoulder is in these extreme positions.

Why Strength at End Range Matters

When the shoulder reaches its end range of motion—whether during an overhead press, a throw, or any extreme movement—your muscles can’t generate the same amount of force as they can when the shoulder is in a more neutral position. This weakness leaves the shoulder joint less stable and more prone to injury.

Without the ability to control the joint at these extreme ranges, you’re at an increased risk of instability-related injuries such as shoulder dislocations or subluxations. Over time, these challenges can lead to wear and tear on the shoulder joint, causing issues like rotator cuff tears, labral injuries, or impingement syndromes.

However, there’s good news! By incorporating targeted physical therapy exercises, you can train your shoulder to be strong even in these vulnerable positions. Strengthening the muscles that support the shoulder at end range can significantly reduce your risk of injury and improve your overall performance in sports and daily activities.

Strengthening the Shoulder in End Ranges with Physical Therapy

At its core, physical therapy is about improving movement quality and building strength where it’s needed most. For athletes and active individuals, this often means focusing on increasing shoulder stability in the ranges of motion where injuries are most likely to occur.

Here’s where physical therapy really shines—helping you develop strength at the edges of your mobility. Instead of simply increasing flexibility, we work to build strength and control in these end ranges. This approach not only enhances performance but also prevents injuries by ensuring that your muscles can stabilize the shoulder joint in even the most extreme positions.

PAILs and RAILs in Shoulder Rehab

One of the best ways to strengthen the shoulder at end range is through Progressive Angular Isometric Loading (PAILs) and Regressive Angular Isometric Loading (RAILs) exercises. These exercises involve applying tension to the muscles in both their stretched and shortened positions, helping to increase both flexibility and strength in end ranges.

For example, Shoulder Flexion PAILs with a Lift Off Challenge and Shoulder External Rotation PAILs with a Lift Off Challenge are highly effective exercises for targeting the muscles that stabilize the shoulder when it’s in its most extended and rotated positions. These exercises focus on developing strength while the joint is near its limit of movement, allowing for greater control and reducing the likelihood of injury.

I recently demonstrated these drills to a group of CrossFit athletes, who need exceptional shoulder strength and stability to lift heavy weights overhead and perform complex movements. However, you don’t need to be a CrossFit athlete to benefit from these exercises. Whether you’re involved in overhead sports like swimming, tennis, or volleyball, or simply want to improve your shoulder health, these exercises are fantastic for anyone looking to build strength and prevent injuries.

Exercises to Try:

1. Shoulder Flexion PAILs with a Lift Off Challenge

2. Shoulder External Rotation PAILs with a Lift Off Challenge

Why Physical Therapy is Key for Shoulder Health

Incorporating these types of exercises into your routine can dramatically improve your shoulder strength and stability, particularly in those vulnerable end ranges of motion. Working with a physical therapist ensures that you’re doing the exercises correctly and progressively, so you can safely build strength without putting your joint at risk.

A physical therapist will assess your specific needs, tailoring exercises to your unique shoulder mechanics and helping you regain control over your movements. With proper guidance, you can significantly reduce your risk of injury and improve your overall performance in your sport or daily life.
