30 Day Ab Challenge – Belly Fat Basics

Belly fat basics

There are 2 types of belly fat, subcutaneous and visceral. So what’s the difference?

If you poke your belly, the soft layer of fat is subcutaneous belly fat, it’s just below the layer of your skin.

According to Harvard Health, this makes up 90% (1).

The remaining 10% is called visceral belly fat and is located beneath the rectus abdominis.

It’s the fat that surrounds your liver, intestines, and other organs. But is also more dangerous.

It’s this kind of fat that we need to focus on.

Visceral fat secretes hormones that trigger inflammation, a risk factor for heart disease and other chronic problems.

It also produces a protein that causes blood pressure to rise.

Visceral fat can also have an effect on many chronic conditions such as cardiovascular disease, dementia, asthma and some forms of cancer.

As we age, deposits of both kinds of fats increase and this is something we need to keep an eye on. But how?

How to Lose Belly Fat

There are many ways to cut down on your visceral fat. 

You’ve probably heard the adage that 6 pack abs are made in the kitchen. So what changes can you make? 

Start simple. Eat more soluble fiber and high protein foods while avoiding trans fats, foods with sugar and alcohol. 

Drink more water! Figure out how much water your body needs and make it a goal to drink that much each day. 

A simple system is to drink eight 8 ounce glasses of water a day. But how can you be sure that that’s enough?

There are many third party water intake calculators if you’re looking for similar content but let’s cover a popular formula based on body weight (2). 

  • Take your body weight in pounds and divide it by 2.2.
  • Multiply that number by your age. If you’re under 30, multiply by 40.
  • Divide that sum by 28.3. 
  • Your total is how many ounces of water you should drink per day. 

If you’re a 150 lbs. 40 year old, you should be drinking 96 ounces of water.

The math: 150/2.2 = 68.18 x 40 = 2,727.27/28.3 = 96.37.

That’s roughly twelve 8 ounce glasses of water.

You’ll need even more if you’re working out.

Secondly, add cardio and resistance training to your routine. Try to reduce your stress (tough I know!) and get plenty of sleep, 8 hours a night. 

Lastly, track your daily life! Focus on tracking your sleep, food, water intake and exercise. 

The easiest way to find out where you need to make improvements is to know what you’re doing in the first place!

Understanding Your Abs

Ab workout challenge

When many people think of abs, they picture 6 pack abs which are just your rectus abdominis muscles.

It is imperative to work the entire core especially in any numbered day ab challenge.

Your abdomen can be broken into 5 muscle groups.

They are your lower abs, obliques, upper abs, serratus and transverse abdominis. The goal is to work all 5 parts.

A strong core workout can also improve your posture, aid in fat loss and can alleviate lower back pain.

How to Do This 30-Day Ab Workout Challenge

Each day, you’ll add 2 to 3 of the identified abdominal exercises explained below to your workout routine.

Take note of your favorites to continue after this challenge!

Each week hold a standard high plank for the time listed below.

Start in a tabletop position with your hands directly under your shoulders or forearms parallel to the sides of the mat.

Engage your core for stability as you step out one foot and then the other.

This is a full body exercise. Press through your hands. There should be a straight line from the tip of your head to your heels.
