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.

Should Your Knees Go Over Your Toes? The Truth About ACL Physical Therapy

If you’ve spent time in a gym or around physical therapists, you’ve likely heard the advice:
“Never let your knees go over your toes!”

This myth has been around for years, but the reality is—your knees should go over your toes—especially during physical therapy and rehab.

Think about it: You can’t walk, run, or even rise from a chair without your knees naturally moving forward. For athletes, movements like deceleration, cutting, and landing demand the tibia (shin bone) to angle forward, known as forward inclination.

Yet, many people recovering from ACL injuries fear this knee movement. After an ACL reconstruction, it’s common for patients to hesitate when allowing their knee to pass over their toes. Unfortunately, avoiding this necessary motion can slow down rehabilitation and leave the patient unprepared for real-world physical activity.

Why Knees Over Toes is Essential in Physical Therapy for ACL Rehab

One of the main goals of physical therapy following an ACL injury is restoring movement confidence. As rehab progresses, patients work on drills that allow for controlled knee translation. This begins with slow, straight-line movements and gradually introduces more speed and direction changes to mimic real-world activities.

Athletes don’t just move in a straight line. They cut, pivot, and absorb forces from multiple angles. This is why physical therapy for ACL recovery involves exercises that recreate these unpredictable movements—giving the knee the chance to regain its strength, stability, and range of motion.

Preparing Athletes for the Stressors of Sports with Physical Therapy

The last thing an athlete recovering from ACL surgery should face is their knee being tested in high-stress situations for the first time during a game. That’s why physical therapy should simulate sport-specific movements in a controlled and progressive environment. This prepares the body for the unique demands of each sport and builds up knee resiliency.

In many cases, the goal is not only to return the ACL-repaired knee to its pre-injury strength but to make it even stronger than before to prevent reinjury.

Rehab That Mirrors Performance Training

This is why end-stage rehab should look like performance training. Athletes need to be ready to perform at their peak—prepared for the physical demands of their sport—before returning to competitive play. Physical therapy should not just focus on recovery but also on preparing athletes for the challenges they’ll face once back on the field or court.

If you’re recovering from an ACL injury or looking for a sports-specific physical therapy approach, we can help you get back to peak performance. Contact us today to learn more about how we tailor physical therapy to meet your rehab and athletic goals!

How Out of Network Physical Therapy May be More Cost Effective

Why Choose Cohen Health and Performance for Sports Physical Therapy?

At Cohen Health and Performance (CHP), we are frequently asked a critical question when someone first seeks our help for pain and limitations interfering with their active lifestyle: Do you accept health insurance?

This is a completely reasonable question, but the answer is more nuanced than a simple yes or no.

Our Mission: Elevating Sports Physical Therapy

At CHP, our mission is to enhance the lives of individuals who prioritize an active lifestyle by providing elite-level sports physical therapy. We are committed to not only helping people recover from pain and injuries but also empowering them to sustain long-term health and peak performance.

This mission drives every decision we make, including our choice to remain out of network with health insurance. For us, the decision was clear—being in-network would make it impossible to provide the high-quality, individualized care necessary to help our patients recover faster, stay injury-free, and return to the activities/sports they love as effectively as possible.

The Limitations of In-Network Sports Physical Therapy

Many people don’t realize how the constraints of in-network insurance impact their quality of care. Due to declining reimbursement rates, in-network physical therapists are often required to see multiple patients per hour—typically 2-3 patients at a time. As a result, treatment sessions become standardized, and truly customized care becomes nearly impossible.

In-network providers frequently have only 20-30 minutes per patient before moving on to the next. This leads to:

Generic treatment plans that don’t address the unique needs of athletes and active individuals.
Over-reliance on passive modalities such as ultrasound and electrical stimulation—techniques with questionable effectiveness in addressing the root cause of pain.
Frequent delegation of care to assistants, aides, or techs, rather than a licensed physical therapist providing hands-on, expert-level treatment.

Because of these limitations, in-network physical therapy patients often require 2-3 visits per week for months to achieve results—if they achieve them at all.

The CHP Difference: High-Quality, Personalized Sports Physical Therapy

By remaining out of network, CHP provides a superior level of care that gets our patients better, faster. Here’s how we stand out:

One-on-one, individualized treatment with a dedicated sports physical therapist every session.
Customized recovery plans designed for athletes and active individuals, addressing not just symptoms but the root cause of pain.
Faster recovery times due to focused, high-quality care, reducing the overall number of visits needed.
Education and injury prevention strategies to keep you pain-free and performing at your best long after treatment ends.

Many of our patients come to us after experiencing limited results with traditional in-network physical therapy. Our approach allows them to return to their sport or active lifestyle stronger, more resilient, and less prone to future injuries.

Is Investing in Out-of-Network Care More Expensive?

At first glance, out-of-network care may seem like a greater financial investment per session. However, when factoring in the cost and frequency of in-network visits, our model often proves to be more cost-effective in the long run.

Here’s why:

Fewer total sessions are needed due to the quality and efficiency of care.
In-network co-pays add up quickly with 2-3 visits per week over several months.
We provide documentation for out-of-network reimbursement through your insurance.
You can use Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) to cover treatment costs.

Investing in Your Health and Performance

When it comes to sports physical therapy, the cheapest option is rarely the best. We believe that your health, well-being, and ability to stay active is simply too important to discount the care that you receive. At CHP, we offer a higher standard of care, ensuring that you not only recover but also gain the knowledge and strength to prevent future injuries.

If you’re serious about overcoming pain, optimizing performance, and getting back to the activities you love—faster and more effectively—Cohen Health and Performance is here to help.

Blood Flow Restriction Training in Physical Therapy

If you’ve ever visited our Bethesda or McLean physical therapy facilities, you may have seen patients wearing unique-looking cuffs around their arms or legs while exercising. At first glance, it might not look like the most comfortable experience, but it’s certainly sparking curiosity among many of our clients/patients at Cohen Health and Performance.

This technique is called Blood Flow Restriction (BFR) Training, and we frequently use it in physical therapy to help patients recover from injuries, maintain muscle strength and mitigate muscle loss. We’ve received many questions about how BFR works, so let’s dive into its benefits and who might benefit from it.

What is Blood Flow Restriction (BFR) Training?

BFR training is a specialized method used in physical therapy that involves placing controlled cuffs around the arms or legs to partially restrict blood flow to those areas. This restriction creates an effect similar to lifting heavy weights, even though the actual resistance is much lower.

This makes BFR especially useful when an injury prevents traditional strength training. Instead of losing muscle and strength due to inactivity, BFR allows us to stimulate muscle growth and prevent atrophy—an essential part of effective physical therapy rehabilitation.

How Does BFR Work?

When blood flow is restricted during exercise, it creates a hypoxic (low oxygen) environment in the muscles. This leads to:

Increased Growth Hormone Production – A key factor in muscle recovery and repair.
Enhanced Strength Retention – Even with light weights, BFR promotes muscle activation similar to traditional strength training.
Faster Injury Rehabilitation – By maintaining muscle mass and strength, BFR helps patients recover more efficiently and return to their activities sooner.

Who Can Benefit from BFR in Physical Therapy?

At Cohen Health and Performance, we integrate BFR into physical therapy treatment plans for a wide range of patients, including:

Athletes recovering from ACL tears or knee injuries
Active adults with calf strains, tendon issues, or post-surgical rehab needs
Individuals with upper extremity injuries, such as biceps tendon strains

Since BFR allows us to effectively train muscles without excessive load, it is a valuable tool in physical therapy for injury recovery, muscle preservation, and performance enhancement.

Is BFR Right for Your Physical Therapy Plan?

If you’re undergoing physical therapy and want to prevent strength loss, muscle atrophy, or delayed recovery, BFR training could be a powerful addition to your rehabilitation program. At Cohen Health and Performance, our Doctors of Physical Therapy use this innovative technique to help patients get back to the activities they love—stronger and faster.

Your Tools to Recovery: What Actually Works?

When it comes to sports recovery, athletes today have access to an overwhelming number of tools—foam rollers, ice baths, saunas, compression boots, and more. But what’s actually worth your time? And what recovery methods truly make a difference?

Our physical therapy team at Cohen Health and Performances work with athletic adults, college and high school athletes every day, helping them overcome injuries and perform at their best. Let’s break down some of the most popular recovery methods and see which ones are worth incorporating into your routine.

Foam Rolling

Foam rolling is one of the most common recovery techniques used in gyms, both before and after workouts. You may even have a foam roller at home that you use on recovery days.

The Science Behind Foam Rolling

The research on foam rolling is mixed. Some studies suggest that it can reduce short-term muscle stiffness and improve flexibility by increasing blood flow to the muscles. However, other research indicates that it may not have a significant long-term impact on recovery.

Should You Use It?

Yes, if… You feel a benefit from it—less tightness, improved movement, or reduced soreness.
Skip it if… You’re just doing it because someone told you to, and you don’t notice a difference.

Like with most recovery tools, if it helps you feel and move better, keep doing it. But if you’re not noticing any changes, it’s probably not a must-have in your routine.

Ice vs. Heat: Which One Should You Use?

One of the more common questions we hear in physical therapy is:
Should I use ice or heat for recovery?

When to Use Ice (Cold Therapy)

If you’re recovering from a recent injury, such as a sprained ankle or muscle strain, icing can help reduce swelling and inflammation. Ice can also be useful after high-intensity activities—like a basketball game or heavy leg day—to prevent excessive soreness and irritation.

When to Use Heat (Heat Therapy)

Heat is great for relaxing tight muscles and improving blood flow. It can be especially beneficial before workouts to increase mobility or on recovery days to relieve stiffness.

Key Takeaway:
Both ice and heat have their place, depending on your needs. If you’re unsure which is best for your recovery, consult with a physical therapist to help you create a plan tailored to your sport and training level.

Compression Therapy: Is It Worth the Hype?

Compression therapy, such as Normatec boots, has become increasingly popular among elite athletes. These devices work by pumping air into different chambers of the boot to promote circulation and reduce muscle swelling.

Does It Work?

📖 Research suggests that compression therapy can help reduce muscle soreness/inflamation and speed up recovery. However, it’s not necessarily a must-have for most athletes.

Should You Invest in Compression Boots?

Use them if… You have access to them and feel they help with your recovery.
Not necessary if… You don’t want to spend money on expensive recovery tools when other free methods (like active recovery) work just as well.

My Favorite Recovery Method: Active Recovery

If there’s one recovery tool that every athlete should use, it’s active recovery.

Instead of sitting on the couch after a tough workout or game, the best thing you can do is get moving.

Try this simple active recovery routine:
✔️ 10-15 minutes of light cardio (stationary bike, walking, or rowing)
✔️ Mobility exercises targeting sore or stiff areas
✔️ Basic bodyweight movement drills to promote blood flow

Why It Works:
Active recovery flushes out waste products from your muscles, reduces soreness, and helps prepare your body for the next workout.

Pro Tip: Professional athletes often dedicate 20-30 minutes on recovery days to movement-based sessions that include light cardio and flexibility work. Implementing this in your routine can boost recovery and prevent injuries.

The 90% Rule

While tools like ice baths and compression boots can be useful, they won’t make a difference if you’re neglecting the basics.

Nutrition – Fuel your body with enough protein, carbs, and healthy fats to support muscle repair.
Sleep – Prioritize 7-9 hours of quality sleep to maximize recovery.
Consistent Training – Train smart and take a thoughtful approach to your programming
Stress Management – Too much stress (physical or mental) can slow down recovery, so make sure you’re managing it effectively.

The basics account for the majority your recovery results. The best recovery tools in the world can’t replace proper sleep, nutrition, and training habits.

Final Thoughts: What Should You Prioritize?

Recovery is not one-size-fits-all. The best approach is the one that helps you feel and move better.

Key Takeaways:

Foam rolling: Use it if it works for you, but it’s not essential.
Ice vs. heat: Ice for recent injuries, heat for stiffness and mobility.
Compression therapy: Helpful, but not a must.
Active recovery: The most effective and accessible recovery tool.
Focus on the basics: Sleep, nutrition, and smart training are 90% of the equation.

If you’re struggling with muscle soreness, an injury, or just want to optimize your recovery, physical therapy can help.

What Stretches Should I Be Doing?

When one of my sports physical therapy patients in McLean recently asked, “What stretches should I be doing?” my answer surprised them: none. While stretching often feels like the go-to solution for muscle tightness, the real issue may not be a lack of flexibility. Instead, the body’s tightness is often a protective response, signaling something deeper that needs attention.

Why Do Muscles Feel Tight?

Muscles don’t become tight without reason. Often, tightness is a response to:

Overtraining or Inefficient Training: If your body senses overuse or improper technique, it may stiffen tissues as a protective measure to avoid injury.
Weakness in Key Positions: Muscles may feel tight because they lack strength in the positions or ranges of motion they’re required to operate in. Without adequate strength, the body compensates by tightening tissues to stabilize and protect itself.

The Role of Strength in End-Range Positions

Athletes, especially those in McLean and Bethesda who engage in high-demand sports like baseball, gymnastics, or weightlifting, frequently encounter this issue. For example, a baseball pitcher’s peel-back position or a gymnast’s overhead movement requires strength and control in extreme ranges of motion. When the body perceives instability or weakness in these ranges, it responds by tightening muscles to guard against potential harm.

This concept applies to non-athletes too. Everyday tasks—like reaching into a cabinet, turning in your car, or bending to pick something up—demand strength in extended ranges of motion. If you’re not strong in these positions, you’re more likely to experience tightness and discomfort.

Exercises That Build Strength and Relieve Tightness

Building strength in lengthened positions can address the root cause of muscle tightness. Two effective exercises we frequently recommend in our sports physical therapy practice are:

Romanian Deadlifts (RDLs):
- Why It Works: RDLs target glute and hamstring strength while promoting core stability in a hinged position. The hamstrings must control the descent of the body and weight, creating tension while lengthening.
- Benefit: When hamstrings are strong through a full range of motion, they feel stable and are less likely to tighten unnecessarily.
Split Squats:
- Why It Works: This exercise builds lower body strength and challenges the hip flexors and quads to stabilize and generate force in a stretched position.
- Benefit: Strengthening these muscles in lengthened positions reduces the likelihood of tightness and enhances overall mobility.

Why Choose Sports Physical Therapy in McLean and Bethesda?

Whether you’re an athlete or just someone looking to move better in everyday life, strength training in extended ranges of motion is crucial. Our sports physical therapy team in McLean and Bethesda specializes in identifying the root causes of stiffness and designing tailored programs to address them.
