Breaking Down Your Muscle Fibers

Every time I hear someone say an exercise targets fast or slow twitch fibers and have zero idea what they’re talking about, drives me crazy. While science is currently investigating I believe the last number I was told was 16 fiber types, the general teaching consensus is 3. Type 1, Type 2a, and type 2x. Fast and slow twitch in the science community btw is slowly starting to fade away because they realized thats not the best way of describing our muscle fibers. But for now, I put them into the blog explanation below:⠀

Your type 1 fibers are known as the slow twitch muscle fibers because they have the slowest firing rate, least amount of force production, and smallest circumference. They are however most resistant to fatigue and have the greatest aerobic efficiency of the other fibers.⠀

Your type 2a fibers are known as your fast twitch oxidative fibers because they have a fast firing rate, produce moderate force, and have a moderate circumference. As opposed to the type 1 fibers, your type 2 fibers fatigue rapidly because of the high force production and they aid in extended work at lower force output.⠀

Lastly, your type 2x fibers are known as the fast twitch glycolytic fibers and have the fastest firing rate of the 3 muscle fibers, the greatest force production, and largest circumference. They fatigue the fastest, but have the greatest creatine phosphate efficiency.⠀

Do Your Cardio!

Did you know that sedentary individuals have a 20-50% greater risk for developing hypertension compared to individuals who are fit?⠀

Regular exercise can decrease your risk of developing hypertension by:⠀
-improving arterial vasodilation⠀
-Facilitating Baroreceptor adjustment⠀
⠀⠀
Overtime aerobic exercise can reduce diastolic and systolic measures of Blood Pressure by 6-7 mmHG. In order to accomplish this you want to make sure you are exercising aerobically 30-60 minutes, 3-4 days per week at a 60-70% of VO2 Max intensity.⠀

Think a personal trainer and healthy food is expensive?⠀

-Hypertension costs the US 64 Billion dollars per year!⠀
-By simply reducing your blood pressure by 12-13 points your risk of heart attack goes down by 21% and any deaths associated with CVD go down by 25%⠀
-a 10% decrease in total blood cholesterol level may reduce the incidence of coronary heart disease by up to 30%⠀
-47% of heart attack and stroke victims die before getting emergency assistance⠀
-90% of all middle aged adults will develop hypertension at some point in their remaining life.⠀

Moral of the story: CARDIOVASCULAR EXERCISE IS IMPORTANT…as much as I hate doing it⠀

Cardio beyond “leaning out”

People do cardio ALL of the time, but not everyone realizes what is happening within when you do cardio the RIGHT way. What we know as cardio is also known as aerobic exercise. ⠀

Aerobic exercise increases the capillary density within muscle fibers and increases type 1 fiber efficiency. Aerobic exercise can also improve ones ability to buffer lactate and increases oxidative enzyme activity. ⠀

In regards to your cardiopulmonary adaptations cardio stimulates an increase in stroke volume, cardiac output, and VO2 max as well as improved cardiac conduction and metabolic efficiency. Cardio should hypertrophy the left ventricle and reduce systolic blood pressure, which reduces myocardial stress and cardiopulmonary energy sparing. ⠀
Research has also shown cardiovascular exercise to increase life span and boost immune health.⠀

Fitness Terms Commonly Misused

Let’s define some words that I see getting misused far too often:⠀
Coordination: Being able to harmoniously perform a movement or how well your body parts interact in order to accomplish a movement.⠀
Speed: Ability to move the body OVER A DISTANCE in a given time⠀
Agility: Your ability to change directions quickly or generate a rapid movement⠀
Balance: How well you disrupt the forces that can disrupt stability⠀

This is important because i see people confuse speed with agility or agility with coordination all of the time. Even other personal trainers. When we understand what words mean we can then gain better understanding of the exercises and their purpose

Aerobic Exercise and Cardiovascular Disease

Aerobic Exercise reduces your risk of developing Cardiovascular Disease by⠀
-Reducing Body Fat
-Lowering Blood Pressure⠀
-Improving your Blood Lipid Profile⠀
-Lowering the risk for myocardial ischemia⠀
-Lowering Risk for Blood Clotting⠀

So even though you might see me joking about how much I hate cardio and try to avoid it on instagram (@letler), it really is important for our health!

New Outlook On Exercise

I challenge you to start looking at exercise as a means for improving your quality of life and not just as a means “to tone” your arms. ⠀

Did you know that exercise can reduce your risk of dying from⠀
-Cardiovascular Disease⠀
-Coronary Heart Disease⠀
-Hypertension⠀
-Colon Cancer⠀
-Type 2 Diabetes⠀

Exercise can be used for so much better than just “to tone.” I mean, if you or a loved one suffers from these diseases or it runs in the family, think about how many more moments with that person would mean to you because they or you decided to take control of their disease and manage it with proper exercise.⠀

10 Pieces of Advice for Getting Over Your Biggest Fitness Hurdles

  1. Have a huge fitness goal?  i.e. losing 80 pounds?  When you first set a fitness goal like that it’s pretty overwhelming, but try breaking it down in increments of 5-10 pounds!  That not only sounds more doable, but mentally it’s more doable as well.
  2. Are you a scale addict?  Have someone in your house hide it from you and only give you access to it 1-2 times a month.  It’ll give you a chance to focus on changes in the way your clothing fits due to measurements changes and not changes on a scale.
  3. Baby Steps!  If you are someone starting off from the very beginning setting a goal like working out an hour a day 6 times a week, may not be very realistic. Start with 2-3x a week for 30 minutes and work you way up?
  4. Sugar addict? Quitting cold turkey doesn’t work for everyone. Focus on cutting back little by little each week.
  5. hire a trainer! Accountability goes a LONG way!  Plus, you are hopefully working out with someone who knows what they are doing so you should see accelerated results.  If you need help, I coach people ALL OVER THE WORLD! Just click here!
  6. Practice self-love.  Instead of criticizing yourself and telling yourself what you are trying to change at the gym, focus on what you LOVE about yourself and let the rest take care of itself with your workouts.
  7. Get a good night’s rest.  Lack of sleep actually inhibits weight loss and increases chances of weight gain and bloating.
  8. Restriction is the enemy, balance is your friend.  Get out of the yo-yo fitness mentality and into a more balanced lifestyles.
  9. Get yourself some cute workout clothes.  Sometimes something as simple as a pair of leggings and a killer tank can motivate you to get your booty in the gym…at least it does for me.  Shop LetlerFit Apparel
  10. Stop thinking of fitness as a chore, no one likes chores, but begin thinking of it as a hobby! Everyone loves their hobbies.
