New Goal Group - Blood Flow Restriction (BFR) Training

Do you want to lift more without putting more stress on your joints? Join Gerry Halverson for 4 weeks of BFR training. This very small group (limited to only 4 people) will train with the BFR system with the goal of improving strength while limiting strain on the joints.

BFR or Blood Flow Restriction training is one of the simplest, most effective tools to enter the strength training world. It has been proven to be an amazing tool to build more strength, in less time, with less wear and tear on the joints. (Learn More)

What’s a Goal Group? A small group of people (4) working with a trainer towards a common goal.

How long is the series? Depends on the goal. For the BFR Goal Group, it is 4 weeks.

Here are the details for the BFR Goal Group:

This class will give you the experience of working with the BFR system guided and supervised by trainer, Gerry Halverson. Class will meet for 1 hour.

What are the benefits of using BFR?

1) BFR mimics heavy weight training without the risks. BFR is a safer way to do resistance training because you can use lighter loads to achieve the same strength gains as using heavy weights.

2) BFR workouts increase Human Growth Hormone (HGH) in the body. HGH helps to build new muscle, reduce inflammation, and improve mental clarity.

3) Shorter sets. When you use BFR, muscle fatigue comes much faster. No need for longer workouts.

Wednesdays at 6pm Starting 2/16/22

Sessions: 2/16, 2/23, 3/2, and 3/9

Only 4 spots available.

Blood Flow Restriction Training (BFR) Workshop

Check out the recording of this event from 9/23/21.

Join Koa Fit trainer, Gerry Halverson, for an informative workshop about BFR. Learn what it is, if it is safe for you, why it works, and the added benefits of utilizing this simple tool.

BFR or Blood Flow Restriction training is one of the simplest, most effective tools to enter to the strength training world. About a decade ago, physical therapists started using BFR as a way to get patients stronger during rehabilitation. Recently, BFR has entered the strength and fitness world as an amazing tool to build more strength, in less time, with less wear and tear on the joints.

August - Bike Month

All month long, we will be going over moves and stretches to keep you healthy on and off your bicycle.

For this first week, we are opening up the chest and shoulders and then keeping them open by strengthening our mid back and shoulders.

This week, we are focusing on hip extension (when the leg extends behind the pelvis). We are starting with an anterior hip release so that we can open the front of the hips and then moving on to an exercise that allows us to strengthen in hip extension.

This week, we are releasing the fascia in our quads to help prevent pain around our kneecap. We are also back on our bellies, strengthening that back line and preventing the shoulders from hunching forward.

This week, we are addressing the upper body. Mobilizing and strengthening our shoulders to help prevent any numbness or tingling while riding. This also has the added benefit of keeping our necks and low backs healthy too.

In the first exercise, this non-relaxing version of a pigeon pose not only gets your hips open, but also strengthens them in your new found mobility so that they stay open.⁠

Then, move on to some bridging with a ball to help strengthen your hamstrings. Strong hamstrings help support your knees and your low back. This exercise is great because it works the hamstrings in both a concentric (muscle shortening) and eccentric (muscle lengthening) way.

July - Foundations Month

This month, we are going to work on some mobility and exercises that everyone should be able to perform. These are the foundations of movement. This is a great place to start if you are just starting out with a movement program, but they are also great tests for those of you who have been moving for a while. You should be able to do all these movements before moving on to more complex movements such as deadlifts. 

For this first week, we are mobilizing the thoracic spine and learning the basics of the hinge. Having a pliable and functional thoracic spine is important in all movement. If the spine does not move properly, you will never be able to generate your full potential over power and this improper function could eventually lead to more serious injury.

We are reviewing the hinge because it is the foundational movement in everything from a pick-up to a squat and is found in multiple movements of daily life (getting in and out of a car, out of a chair, picking up things off the floor, etc.).

For our 2nd week of Foundations Month we are moving from the spine to the feet and we are going to progress our hinge to the squat.

This week, we are using a squat to help us gain some motion in our ankles. Now that you learned the proper squat last week, you can use this version to help bring some mobility to your ankles and feet. We are also going to learn how to use the hinge for our lunge. ⁠

This week, we are going after the low squat. The low squat should not just be for the privileged few. It is one of the most useful and functional positions you can utilize. From picking up heavy things, to getting up and down from the floor, the low squat is a necessity in life.

We are finishing up Foundations Month with the staple exercise of the dipping bird. We have been working all month on our hinging and strengthening our posterior chain. Now, let’s challenge it with this single leg balance move.⁠

June - Trail Month

For the month of June, we will be working on getting ourselves trail ready. We will post a new stretch and a new strengthening exercise each week on this page and on our Facebook and Instagram platforms. Check out our stretches and moves all month and keep yourself safe out on your adventures.

For week one, we are stretching out our quads with a standing stretch that can be done anywhere. Then we are keeping our hips (and knees) happy with a lateral hip strengthener.

This week, we are stretching our hamstrings and again, this standing stretch can be done anywhere. We are also working on a variation of a squat that helps strengthen our legs in multiple planes.

Does your low back get cranky out on the trail? Try this hinge stretch to get some relief. Then strengthen the hips and core with this banded exercise to keep your back and knees healthy as you blaze the trail.

For our final week of Trail Month, we have one, final standing stretch. This one opens up your sides which can start to feel compressed after a long day out. We are also working on our cores with a banded exercise.

Dr-Karen-Kaufman-FB-Profile-600.jpeg

While practicing in Boulder, Dr. Kaufman became aware that patients needed and wanted more than what they were receiving from traditional Western Medical healthcare. She observed that while some patients felt better with certain medications including bio-identical hormones, a large percentage continued to not feel “well” or had even more symptoms because underlying issues were not addressed. Through these observations she became passionate about functional, integrative medical care and incorporating more holistic approaches with patients. As a result, she pursued a fellowship in Functional Medicine to develop a deeper understanding of the underlying triggers that keep patients from experiencing their optimal health.

In 2019 Dr. Karen Kaufman was invited to join the Case Western Reserve School of Medicine Advisory Board. She is the first member of the board with a background in functional, and integrative medicine, in addition to being a board-certified Obstetrician/Gynecologist. The integrative, functional model has given Dr. Kaufman an entirely different perspective about how to approach a patient’s symptoms and complex medical issues.
