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.

Exercises that I don’t do anymore as a physical therapist

If you’re an active adult who values fitness and staying in peak condition, you’ve probably encountered the occasional advice on “must-do” exercises. But, as our bodies and needs evolve, certain exercises may no longer serve us as well as they once did, or they may come with risks that outweigh their benefits. At Cohen Health and Performance, we’re committed to helping clients in Bethesda and McLean stay active and injury-free with exercise choices that prioritize safety and effectiveness.

Recently, I was chatting with a former colleague about the early mornings we used to spend training professional athletes. Back then, our routines were packed with intense, high-demand exercises designed to build serious strength and endurance. But over the years, I’ve fine-tuned my approach and adjusted my own workouts, replacing some exercises with alternatives that are safer and yield excellent results—especially for those of us who aren’t competing professionally but still want to stay strong and healthy.

Here are two exercises I no longer include in my routine, along with the safer, more efficient alternatives I recommend to clients who want to build strength and minimize injury risk.

1. Moving Beyond the Plank: Core Stability Without the Strain

Planks are a classic core exercise and have become wildly popular for strengthening the abdominals and shoulders. However, planks aren’t always ideal for everyone. Holding a plank for extended periods or performing them without perfect form can put excessive strain on the lower back, which is especially risky if you have existing back issues or aren’t engaging the right muscles.

Instead of traditional planks, I now recommend bear variations, like the bear crawl or bear plank. Bear variations are dynamic and can be modified to target core stability and strength without placing undue stress on the lower back. The bear plank, for example, involves holding a position on all fours with knees hovering just above the ground. This position naturally activates your core muscles while keeping the spine in a better position, significantly reducing the risk of back strain.

For active adults in Bethesda looking to maintain core stability and train safely, bear variations are a great choice. They challenge the core in a more effective way, promoting good posture and balance—skills that are essential not only in the gym but in everyday activities.

2. Replacing the Barbell Back Squat: Safer Alternatives for Building Lower Body Strength

Another staple of strength training is the barbell back squat, an effective exercise for building lower body strength and muscle mass. However, barbell back squats lots of mobility and solid form to avoid injury, especially to the lower back. For many people, this level of mobility and movement competency isn’t practical without extensive preparation, and the risks may outweigh the benefits.

Safer alternatives like goblet squats and safety bar squats offer the same benefits with less risk. Goblet squats, which involve holding a weight in front of your chest, are accessible for most people and help engage the core, which can further protect the lower back. Safety bar squats, which use a specially designed bar to keep weight distributed more comfortably, allow for better form and greater ease in maintaining an upright posture. Both exercises are fantastic for strengthening the legs, glutes, and core while minimizing the risk of injury associated with traditional back squats.

For active adults focused on maintaining mobility and avoiding injury, these squat alternatives offer a way to build lower body strength without the complexity and potential drawbacks of a barbell squat. If you’re working with a physical therapist in Bethesda, they may even recommend these variations as a part of your strength-building routine, especially if you’re managing previous injuries or aiming to improve overall stability and function.

The Power of Purposeful Exercise Selection

When designing a workout program, one of the most important questions to ask is: What is the goal of this exercise? For most active adults, the goal is to build strength, look good, and avoid injury—keeping you strong and capable for years to come. At Cohen Health and Performance, we focus on exercises that provide maximum results with minimum risk. By selecting exercises that target the right muscles without overloading the joints, we create workouts that help you achieve your goals safely and sustainably.

Our philosophy is simple: every exercise in your program should have a clear purpose, whether it’s improving strength, boosting flexibility, or enhancing functional movement. This approach guides all the programs we create, from personal training sessions to physical therapy in Bethesda and McLean, helping clients stay active and reduce the likelihood of injury.

Speed Kills: tips to gain that extra edge

As a parent of a high school athlete aiming to compete at the collegiate level, you understand that speed can make all the difference. Faster athletes often outshine their competition, even in physical sports like football, where speed is a game-changer. Fortunately, there are proven ways to help your athlete enhance their speed and give them a competitive edge, whether they’re on the field, track, or court. Below are drills that we incorporate with our sports physical therapy and performance training clients.

Speed Training Essentials for Aspiring College Athletes

Boosting speed requires a comprehensive approach that goes beyond simply moving faster. Here are three key areas to focus on for your athlete’s speed development.

1. Master the Basics

Just like any other skill, sprinting has specific techniques and the mechanics are where we start as sports physical therapists and performance coaches. Practicing sprint mechanics, such as proper foot strike, forward knee drive, and core activation, is fundamental to achieving an efficient stride. Incorporate drills that reinforce these mechanics, such as marching, skipping, and high-knee runs. These simple yet effective drills provide a strong foundation and encourage form that can help increase speed safely.

Recommended Drills:
– A March

– A Skips

– Stepover Drills (Shin Height)

2. Build Strength in Key Muscle Groups

Running fast requires strength, especially in muscles like the quads, hamstrings, calves, and core. Building strength in these areas is essential not only for speed but also for power, endurance, and injury prevention. Compound lifts and single-leg strength exercises targeting these muscle groups are highly effective in making strides more powerful and reducing the likelihood of injury.

Strength Training Exercises:
– Standing Hip Flexion With Band

– Front Foot Elevated Heel Raise

– Copenhagen Hold with Reach

3. Practice Accelerations and Sprint Drills

A well-rounded speed training program includes work on both acceleration and top-speed mechanics. Acceleration drills help athletes reduce the time it takes to reach their maximum speed, while sprint intervals build stamina for sustained performance. Integrating these drills into regular training can drastically improve an athlete’s on-field performance.

Suggested Speed Drills:
– Wall Acceleration Series

– Sprinter Step Up

Sprint Workouts:
– Flying 10s: Build speed over 20-30 yards, sprint for 10 yards, then slow down.
– 10×10: Sprint for 10 yards, then decelerate quickly; repeat 10 times.

What Performance Physical Therapist, Dr. Biddle, learned from breaking her leg

I’m thrilled to welcome Dr. Catherine Biddle to our physical therapy team in Bethesda. Dr. Biddle specializes in treating gymnasts, dancers, and athletes with hypermobility related conditions. As a former Division I gymnast at Northern Illinois University, she brings both expertise and personal experience in overcoming sports injuries.

She was kind enough to tell us about the injury that inspired her to become a sports physical therapist and what you can learn from her journey.

______________________________________________________________

At 15, I suffered a serious injury during gymnastics practice. While performing a skill called a blind full on bars, I turned too early, causing a fall from 12 feet onto concrete. The result? A broken fibula in three places and a dislocated tibia.

Two days later, I had surgery to insert a plate and eight screws in my leg. My doctors warned I might never compete at the same level again. As a gymnast for 13 years who was being actively recruited by colleges, this news was devastating. I felt lost—until I started physical therapy three weeks after surgery.

When I crutched into my first physical therapy session, feeling hopeless, my therapist did something powerful: she asked me how I was doing—not just physically, but emotionally and mentally. That conversation changed everything. She told me that while recovery wouldn’t be easy or fast, we would do everything we could to get me back to gymnastics. Thirteen months later, I joined a Division I gymnastics program and had a fulfilling collegiate career.

My injury taught me that the physical therapy journey is about more than just the body. It’s about mindset, support, and perseverance. The right therapist can make all the difference, helping you heal both physically and emotionally.

Most importantly, I learned that a surgeon’s prognosis isn’t the end of the story. With the right support system, a positive outlook, and hard work, you can overcome obstacles you never thought possible.

These lessons shape how I approach my work today. I focus on more than just my patients’ injuries—I consider how they’re feeling overall and what their goals are. Healing isn’t just about “fixing” the problem; it’s about helping people return to the activities they love.

So how do you know if you’ve found the right healthcare provider for you?

Ask questions!

Prior to your visit, prepare a list of the questions that are important to you. Your provider should be willing to answer all of your questions, even if they can’t give you a definitive answer at the moment.

Here are 3 questions that I advise asking.

1. Why did this happen, and how can we prevent it from happening again?
Understanding the cause of your injury helps ensure it doesn’t become a recurring issue.

2. What should I be doing at home?
Recovery extends beyond the clinic. Make sure you’re clear on what exercises or precautions you should follow at home.

3. How will we measure my progress?
Your goals should guide your recovery, not just standard benchmarks. Set clear expectations with your therapist to track meaningful progress.

Physical therapy is most effective when it’s a partnership. The more engaged you are in your recovery, the better your results will be. Asking these questions helps you take control of your health and build a stronger relationship with your therapist.

Key Takeaways from a Fitness Competition

This past Saturday, I had the privilege of being the performance physical therapy sponsor at an incredible event to raise funds for breast cancer research—Girls Gone RX, hosted by our friends at Crossfit Route 7 in Tyson’s Corner.

From the moment I stepped through the doors, I could feel the energy. A throwback mix of NSYNC, Backstreet Boys, and Britney Spears filled the air, instantly taking me (and probably many others!) back to the days of Total Request Live on MTV.

But it wasn’t just the music that made this event memorable—there were some amazing takeaways from the competition that can apply to physical therapy, or any sport or workout routine. Here’s what stood out:

The Power of a Supportive Environment

One thing CrossFit does exceptionally well—especially at CrossFit Route 7—is foster a fun, supportive community. It was inspiring to see how excited everyone was to be spending their Saturday at the gym, whether they were competing or cheering on the athletes. The event was a women-only competition, yet both men and women were there in full force, cheering loudly from the sidelines.

The participants ranged from beginners to seasoned athletes. Some were lifting impressive amounts of weight, while others were simply excited to be part of the action. The diversity of skill levels only added to the event’s energy and made it even more inclusive. A supportive environment doesn’t just apply to fitness, it matters in healthcare and physical therapy as well.

Taking Warm-Ups Seriously

These athletes were no strangers to competition, and their warm-up routines showed it. Before each event, competitors spent significant time preparing, but these weren’t your typical, one-size-fits-all warm-ups. The exercises were specifically tailored to the movements required for each event.

For example, before an event involving barbell cleans, the athletes took time to perfect their form, using weights similar to what they’d be competing with. It was impressive to see how much attention was given to detail, and it served as a reminder that a good warm-up should transition you smoothly into your workout. By the time the event began, most of the athletes had already broken a sweat, minimizing the risk of injury.

Master the Basics

Most of the women competing had clearly spent countless hours honing their skills. CrossFit requires a blend of mobility, strength, and technical expertise. It’s tempting to jump straight into the fun aspects of a sport, but this event was a great reminder that you must master the prerequisite qualities of any activity first for long-term success.

Just like building a house, laying a strong foundation is key before adding the finishing touches. Whether you’re a beginner or a seasoned athlete, it’s essential to invest time in developing the movement patterns and technical skills that pave the way for long-term success and injury prevention.

A personalized movement assessment can make all the difference, helping you stay injury-free while enjoying your favorite sport. If you’re interested in learning more about how to get your own custom movement evaluation, contact us!

Grandma was wrong about this

Growing up, my grandma, Barbara, lived next door to us. She was a character—loving, funny, self-deprecating, and wise. I was lucky enough to spend time with her daily, soaking up her advice (whether I wanted it or not!). And while most of her advice was pure gold, there was one thing she got wrong—something I later discovered through my experience in sports physical therapy.

When I’d come home slouching, she would lovingly tell me to “stand tall” by bringing my shoulders down and back so that “all the girls could see my handsome grandson.” She certainly helped boost the confidence of an awkward middle schooler with buck teeth and a terrible haircut, but when it comes to posture, her advice wasn’t quite right.

You’ve probably heard the same thing: “pull your shoulders down and back” to stand tall and improve your posture. It sounds good, but through my work in sports physical therapy, I’ve learned that this advice can be counterproductive to how your shoulders are designed to work.

The Problem with “Shoulders Down and Back”

In sports physical therapy, we often encounter athletes and active individuals who believe that pulling their shoulder blades down and back improves posture. However, doing so actually prevents your shoulder blades from moving the way they should. Your shoulder blades (scapulae) are designed to move away from the midline of your body—a movement called protraction.

Protraction is crucial for everyday movements like reaching, throwing a ball, and pressing weights overhead. Restricting this natural movement by pulling the shoulder blades together can cause upper back tension and limit mobility—issues that are frequently addressed in sports physical therapy.

Why This Matters for Athletes

If you lift weights or participate in sports like baseball, football, or basketball, maintaining proper shoulder mobility is key. Through sports physical therapy, we see how athletes benefit from training movements that allow the shoulders to move naturally. Pinning your shoulder blades back limits your ability to build strength in outstretched positions, which are crucial for both athletic performance and injury prevention.

Great athletes need fluid, strong movements with their arms in extended positions. Constantly pulling the shoulder blades together limits the opportunity to build the functional strength required for peak performance in sports.

3 Exercises for Better Shoulder Mobility & Strength

As a sports physical therapist, here are three exercises I recommend to help athletes and active individuals improve shoulder mobility and build strength in these outstretched positions:

1. Core Push-Up – Build strength around the shoulder blades by actively pressing them away from the midline, which is essential for shoulder health in sports physical therapy.

2. Bottoms-up Kettlebell Press – This overhead pressing exercise forces the body to stabilize a kettlebell while pressing overhead, improving both shoulder mobility and strength.

3. Shoulder Flexion PAILs and Liftoffs – Develop strength in overhead positions where it can be challenging to maintain proper form and stability.

These exercises are staples in sports physical therapy to help train the shoulders to move more effectively, enhancing performance in sports and everyday activities.
