It’s a beautiful morning on race day, you’ve trained for this and it’s time to begin. The starting gun goes off, your running through the course at your best time yet. You feel great until, near the end of your run, you feel a wave of fatigue and mental exhaustion hit you like a headwind. You slow down, feel irritated and your body begins to run out of energy as you realize that you have hit the dreaded ‘wall’.

Whether you call it ‘bonking out’ or ‘hitting the wall’, long distance runners cringe a little when hearing those words since most have experienced this phenomenon either during training or on race day.

But how can we avoid smacking into this non-tangible wall face first? Many runners would think that increasing their carb intake would have the most substantial effect, but it may not if that energy is being wasted on poor running mechanics.

What if, along with proper carb loading strategies, we can train your body to be more efficient with each stride that you make? That way, you can utilize your energy stores to help you push through the last few miles!

Let’s break this down, to have you training effectively for your next race, by looking at the following:

1) What is this ‘wall’?

2) Why plyometric exercises can help?

3) What plyometric exercises should I use?

So, let’s get into it:

What is this ‘wall’?

This ‘wall’ refers to the point where your glycogen (converted carbohydrate stores) are fully depleted. When that fuel source is tapped out, your body goes into a ‘preservation mode’ with our muscles and even our brain. That is why, when you hit this stage, negative thoughts may sprint into your head like, “I shouldn’t be doing this!” and “Everyone is doing better than I am. I should just quit now and find the nearest tub of ice cream!”.

From what we described, it sounds like everything can be fixed by just adding on more carbohydrates and electrolyte supplements, right? This leads to our next question… 

Why plyometric exercises can help?

Plyometrics, or ‘Jump Training’ refers to training your muscles to produce both strength and speed effectively. Essentially, plyometric training helps you to generate force in a strong and efficient manner. The better that you can produce force in a quick and controlled manner, the better you can control your body movements and the more efficiently you will run! 

By doing this, you may improve your running efficiency (economy) (RE) and improving your RE will help you use less energy to run the same distances that you have in the past, keeping energy for what’s important, running the best race that you can!

Take a second to take in that info. Once you see the positive changes that this can provide, we need to now consider our final question…

What plyometric exercises should I use?

If you’re a runner, or want to become a runner, you should use what time and energy, outside of training, on the exercises that matter most. For your plyometric training, we need to focus on two things:

1) Force Absorption

For that, let’s work on this: 

Depth Jumps: 

* Begin by using a box or step that is knee height or shorter.

Stand on top of the box at the edge and drop down landing softly on two feet. Once you land, immediately jump up and extend vertically. Land softly again in a squat to complete one rep. • Coaching Point! Make sure to land with your toes touching the ground first and then sink into your heels before your next jump. Your goal is to land as quietly as possible! That way you teach your body to absorb force.

2) Force Production

For this, were going to use:

Lateral Line Hops: 

* Stand with both feet together with the outside of your foot on one side of a line marked on the floor.

Begin by pushing through your toes to jump both feet to the opposite side of the line. Once you land, immediately jump again to return to the starting point on the original side of the line.  • Coaching Point! Keep your knees and hips soft while you primarily make the jump through your ankles like you are jumping rope. The jumps should be quick and you should spend as little time on the floor as possible. That way we work on producing the best jump through the floor as possible.

Give these moves a shot to help you perfect your form for race day!

No Time to Run? 11 Strategies to Bust Barriers to Exercise

Community Contributor: Whitney Heins, Founder of Mother Runners, Knoxville, TN

Whitney Heins, Founder of @themotherrunners

Us Mother Runners know that none of the barriers to exercise have been as steep as the ones present in parenthood—demanding schedules, sleepless nights, illness, feedings, separation anxiety, the list goes on.

Before becoming a mom, it was just me and my willpower. But now, other human beings are in the equation and it requires a network of people, intense schedule coordination, and some sacrifice to get out the door. I’m still getting the hang of it, but here are some strategies that have worked for me—and hopefully they may help you, too.

1.     Get it on the calendar. My husband is a runner, too, so for both of us to get our exercise in, we have to coordinate. One of us may have to run before dawn, or forgo dinner. With busy schedules and young kids, it’s something we discuss daily to ensure it happens. Gone are the days of the spontaneous jaunts. 

2.     Go early. For a lot of people, getting up early to exercise is a bitter pill to swallow. But that cup of coffee in the quiet hours of the morning is absolute bliss, and quite the motivator—so is meeting up with a friend to get in a few miles. Also motivating? Knowing that you started the day off right before anyone else in the house is awake. 

3.     Work it in. Sometimes there just isn’t enough time in the day—so you have to multi-task. I’ll do barre moves while I hold my son up on the counter to play in the kitchen sink; or take work calls while running (with the disclaimer that I may be heavily breathing while talking).

4.     Get equipped. If you’re home with the kids and they’re napping or otherwise occupied, harness that free time at home by investing in a treadmill or elliptical, or whatever. This also comes in handy during treacherous weather.

5.     Make it a family affair. We go on “family adventures” where the kids get a morning full of hikes by the river, playtime at the park and muffins at the local bakery. They aren’t ones to sit in the stroller long, so stops along the way entice them to join us while we get some exercise in. Obviously, this run isn’t the type for workout—but it can suffice for an easy training day.

6.     Tack it on. The attachment with our kiddos is strong—like cry for hours after we leave strong. So instead of doing the “duck and run” to get out the door, only to do it again when we want to exercise, it’s much easier to tack a workout on to whatever we left the house for in the first place. Have a meeting or a lunch break from work? Bring your gear and save some tears!

7.     Ask for help. We’re all busy and sometimes you just need a little help from a friend—or family member—to watch the kids while you get a workout in. Ask for it. I used to feel selfish asking for someone to watch my kids while I ran but now I realize the benefit running has for not just me—but my whole family!—a healthier, happier mama.

8.     Tell yourself, it’s okay. Confession. I have serious mom guilt and almost always used to feel bad when I’d take time to run. But, I know I need it like I need food and water. And, I know I am a way better mom, wife, and person if I get to run. And, I know it’s good for me—in the long and short run.

9.     Hit up child care. I know many Mother Runners who have found great workout facilities that offer child care while they exercise. For these moms, it is a win/win. The kids have fun and they get movin’.

10.  Make it nonnegotiable. Making an appointment for yourself to go running and don’t let other things stand in its way. Treat this time as if it is a doctor’s appointment or work meeting. Put it on the calendar, and have it stay there.

11.  Throw in the towel. Hey, some days it’s just not possible (and if you’re dealing with pretty bad illness, it’s not smart). It’s okay! Tomorrow is another day.

Happy running!

What would Phil do?

Phil Barber 1955-2019

Not everyone sets out to be the greatest in the world. Some strive to be the greatest for the world without even realizing it. That man was Phil Barber and he was my first real friend in Knoxville. He was the type of person who would free up his time to talk to you, check in with you, and make sure you were doing alright. He went out of his way to make sure everyone knew that they mattered. He wanted everyone to feel welcomed in the Knoxville running community. He attended darn near every single run during the week and tried to talk to every single person he met. He was always so fascinated and inspired by everyone never realizing that he was the one inspiring others. He’d always go out of his way to help folks the moment he became aware of the need. He would literally give you the shirt off his back. One trait that always sticks out to me and used to get on my nerves was his advice on how to get better at running. He didn’t believe in going to gyms or gimmicks. He thought folks should simply run more. He would often message me saying “Are you running tonight? You need to run.” Or “You need to be doing consistent 10-12 mile long runs on weekends. We both should be doing that. You are fully capable of doing it.” Sure I was capable, but I didn’t want to run that much to be honest… I did anyway because…well…Phil. The point is that he wanted to see me get better. He wanted everyone to be better than they once were because that’s what he had done. Here’s a guy who lost everything during the recession, but rather than sit around and complain about it, he set out to improve himself mentally and physically. So he started to run… a lot. That led to 15 marathons in 12 months to be exact and that’s not even including the fun runs he was still running at during the week! The way he treated others is a message we should etch into our memories, so that we could be the Phils everyone needs in their lives: showing compassion and grace, calling friends just to tell them that we care about them, running even when our lives feel out of control, helping others, and playing our music so loud that those around us can’t help but remember us as we pass by. Phil, I love you so much and feel so honored to have had you as my friend.

Why do YOU run??


I wanted to try something new with the posts…

I want to know WHY people run.

For me, I started running because I was out of shape from having a baby and had zero friends when I moved here. I wanted to be healthy and surround myself with great people who happen to run. Now I’m healthy and am friends with great people!

…so why do YOU run?

When the weather is crappy or sunny, what keeps you running?

Why do you keep showing up at the Group runs, gyms, or for long or short runs?

What got you started with running?

What keeps you coming back?

I would love to repost YOUR story with a picture to represent the runners of Knoxville!

Benefits of a Sports Massage

massageI’ve come to the realization that injuries are preventable if you actually take care of yourself.

The nagging pain in my calves has continued despite foam rolling, cupping, and dry-needling. I’ve been told it was due to my flat feet, misalignment of my hips, not stretching, over running, etc. Whatever the cause of the problem has been, it has caused my calves to over compensate and become insanely tight to the point of stiffness and constriction. The cupping and dry-needling provided temporary relief; however, the problem continued to be an issue until my chiropractor finally suggested that I go and have my legs massaged.

I scheduled a sport massage for my legs with Carter Sport Therapy and was greeted by Dianna Christmas, LMT. Upon arrival, she had me fill out a questionnaire regarding my problem areas, level of pain, and the standard medical questions regarding my health. I was then taken to a semi-private room to change into shorts and walk around the room, so she could determine my level of mobility.

She performed a massage or manipulation that included their Myofascial Integration Technique (MIT), which is a deep, penetrating manipulation designed to restructure the muscle and soft tissue by creating space in the body allowing for an easier and freer range of motion and promoting relief of many chronic painful conditions. After the massage, she had me walk around to see if my flexibility and mobility had improved. My legs actually felt lighter and I could immediately feel the difference in my calf.

She then showed me Active Isolated Stretching (AIS) techniques that would prevent my muscle tightness from reoccurring. These active-assisted stretch techniques were used to increase tissue-joint movement and improve physiological function, increase range of motion in joints, create more fluid movement, and unbind tight and/or taut muscles.

The benefits to massage include, but are not limited to:

  • increased blood flow
  • reduced muscle tension and neurological excitability
  • increased sense of well-being
  • increased muscle compliance resulting in increased range of joint motion
  • decreased passive stiffness
  • decreased active stiffness
  • enhanced performance
  • reduced risk of injury
  • enhanced recovery
  • decreased pain and fatigue

Conclusion: If you want to maintain peak performance and prevent injury, I highly recommend taking care of yourself with regular maintenance. Make it a habit to stretch before and after exercise. Don’t be afraid to have a professional massage those knots and tight muscles, so other muscles won’t have to overcompensate. I also highly recommend finding a practice that specializes in athletic performance, postural issues, injury recovery, injury prevention and flexibility enrichment like what Carter Sport Therapy offers.

A.R.T. and Chiropractic Adjustments

chiro dr joh

“As a chiropractor, my goal isn’t just to help you heal from injury. It’s also to help you learn to prevent injury from occurring. I make use of a variety of diagnostic procedures from a multitude of chiropractic and neurologic disciplines, which reveal faulty neurological conditioning, aberrant movement patterns, joint fixations, muscle weaknesses and incorrect muscle recruitment.”

Dr. John, Sport and Wellness Chiropractic center

Dr. John’s chiropractic office stands out from the rest because he includes Active Release Techniques (ART) with his chiropractic adjustments. These pin and stretch massage techniques are protocols for problems in the upper and lower extremity of the body and are considered the standard for soft tissue evaluation and manipulation in the sporting community. This combination of chiropractic and myofascial manipulations can accelerate the healing process for injuries, aid in the prevention of sports-related injuries, and is guaranteed to make anyone faster after just one visit. Dr. John is also an extremity specialist, one of only a few in all of TN. He was recently awarded the accolade of Best Chiropractor by West Knoxville Lifestyle Magazine!

Benefits of chiropractic adjustments complemented by Active Release Techniques:

  • Reduced lower-back pain
  • Increased functional outcomes
  • Reduced frequency of migraines
  • Cost-effective treatment
  • Shorter recovery time
  • Increased flexibility
  • Decrease in pain-medication dependency

Personal Experience

Prior to the visits, I was dependent on migraine medication every other week due to cluster migraines from chronic tension. I also suffered from lower back that would cause my lower back to pop and tighten up when I’d bend over. Another issue I dealt with were ginormous knots in my calves that caused them to always be flexed. The issues negatively impacted my running, cadence, and speed.

After 4 visits of chiropractic adjustments and Active Release Technique massages, I haven’t had any headaches or migraines, my lower-back pain is completely gone, and my calves are slowly loosening up. As far as athletic performance, my flexibility and cadence are improving each week. I was also able to shave 20-seconds from my running pace.

I like how Dr. John doesn’t bash other offices or services. He offers his services and explains the techniques in detail. Because I have sprained both ankles on multiple occasions, he was sure to ask me if I had seen a physical therapist to remedy them. My calf muscles need a deeper Myofascial release that can’t be worked out in one chiropractic-ART session, so he recommended that I see a massage therapist.

As a runner, I want to be able to run without pain and having a provider that offers services and recommendations that will prevent further injury has helped me do just that. If you’re in the market for an ART certified provider and need an adjustment, I highly recommend that you check out Dr. John at Sport and Wellness Chiropractic!

Cryotherapy in the Cryobus

IMG_8628When it comes to muscle recovery and injury prevention following long training runs, I usually opt for an ice bath. I’ve found that ice baths prevent muscle soreness and cramps. The downside to ice baths include buying the large bags of ice, pouring them into the tub, and mustering up enough willpower to actually get into the ice bath. Once in, it is really a struggle to sit in the bath long enough for the benefit to take effect as 5-10 minutes feel more like hours in the frigid water.

This is where Cryobus and cryotherapy completely change the game. Cryo originates from the Greek word meaning ‘cold’ and therapy which means ‘cure.’ The Cryobus travels to locations all over Knoxville. The Cryotherapy chamber is kept at -130 to -184 degrees F and the chill options are set for 1, 2, or 3 minutes. This is half the time of a typical ice bath.

Proven benefits of the Cryotherapy include, but are not limited to:

  • Decreases muscle soreness
  • Reduce Pain, swelling, and Inflammation
  • Reduces delayed onset of muscle soreness
  • Increases energy and athletic performance
  • Allows more intense and higher volume training
  • Improves muscle strength and joint function
  • Overall faster return to sport training
  • Decreases injury recovery time
  • Decreases levels of oxidative stress

Tips before you visit the Cryobus:

  • Bring a dry change of metal free clothing
    • Ladies– wirefree sports bra and spandex/short shorts
    • Guys– wirefree spandex or short shorts
    • You want as much ice-to-skin contact as possible for the highest level of benefit to occur
  • Remove all jewelry, especially any metals
  • The Cryobus team will provide you with socks, slippers, gloves, and a robe.

Here’s how the Cryotherapy session went for me:

First, I put on a pair of socks, gloves, and slippers provided by the Cryobus team.


Then I was fitted for the chamber to ensure that my head would be above the ceiling hole. They added a few cushion pads to the floor.


Then, I stepped in with the robe on, slipped off the robe, and gave it to the staff through the top of the chamber. I slowly rotated my entire body around for the 3 minutes that I was inside of the Cryotherapy chamber while keeping my head above the hole at all times. When the time was up, they handed me back the robe through the top of the chamber.


Personal Results

I equated the session to results I usually get from an ice bath following a long run. What I really enjoyed about the visit was that they walked me through the entire process, supplied me with gloves, socks, footwear, and a robe to keep me comfortable. Best of all, I wasn’t left cleaning up anything like I usually am after an ice bath. There are only 2 locations of Cryotherapy currently available in Knoxville and the East Tennessee Spine and Sport Cryobus that I was able to try actually comes to locations near you! If you’re interested in giving this style of recovery a try, you can contact them at Visit their website at and be sure to follow the @cryobus on Instagram!
