Fitness trainer breaks down 3 causes of chunky calves and how to fix them

The calves are often one of the most stubborn areas to slim down. Both too little and too much exercise can lead to the development of "cankles" or thick calves. While long, slender legs can visually elongate your proportions and make you appear taller, thick calves can easily make you look heavier—a common frustration for women who love wearing short skirts. A fitness trainer has deconstructed the three main causes of thick calves and introduced targeted exercises for each type to help you achieve slender leg lines.

Cankles: Understanding Fluid, Fat, and Muscle Types

According to a report in Women's Health, personal trainer Kenta Hayashi explains that the three primary reasons for thick calves are fat accumulation, fluid retention (edema), and muscle tightness. Understanding the characteristics of these three causes can help you find the corresponding solution.

1. Fluid Retention Type (Edema)

This is usually caused by prolonged standing or excessive salt intake. Mild swelling can be relieved through bathing or myofascial release. However, if the subcutaneous tissue hardens, it can lead to persistently thicker calves.

2. Muscle Type

The gastrocnemius and soleus muscles are the two main muscles of the calf, collectively known as the triceps surae. They are the second-largest muscles in the lower limb, following the quadriceps at the front of the thigh. Therefore, having some calf muscle is a sign of health. However, when muscles become tight due to exercise, they can appear bulky. The soleus is an inner muscle particularly prone to hypertrophy (enlargement), while the gastrocnemius, located on the outer side, is more likely to bulk up from explosive movements. Consequently, people who engage in sprinting and jumping are more prone to muscular, tight calves than long-distance runners. That said, it's rare for calves to become overly bulky just from daily life or moderate exercise.

3. Fat Type

Due to lack of exercise or excessive calorie intake, fat accumulation can cause the calves to become rounded and soft overall. The gastrocnemius is the main calf muscle, also used when bending the knee. Large-scale foot movements centered around the hip joint can stimulate the knee, effectively working the gastrocnemius and making it easier to tone.

On the other hand, if you habitually take small steps, using only your ankles and knees for power, the gastrocnemius can't function properly, making it easier for fat to accumulate. Moreover, areas with less muscle tend to store more fat, creating a vicious cycle. So, the first step to slimming calves is to move them as much as possible.

3 Essential Calf-Slimming Exercises to Beat Edema and "Cankles"

Hayashi notes that even small lifestyle changes can significantly impact the appearance of your calves. Paying attention to your daily walking style and posture, combined with leg-slimming exercises suited to your needs, can lead to slimmer, more toned calves. Here are habits and exercises that build the three different types of thick calves:

1. For Fluid Retention Type (Edema)

• Strategy: Move your lower body and ankles frequently. Try not to maintain the same position for long periods, including prolonged standing.
• Recommended Exercise: Calf Stretches
  • For those who sit for long hours, stretching the back of the thighs simultaneously can also help improve poor posture.

2. For Muscle Type

• Strategy: Avoid explosive movements that put significant stress on the calf muscles, such as jumping or sprinting. Instead, incorporate stretching to increase muscle flexibility. For those who already exercise regularly, switching to an aerobic training style can also be very effective. Long-duration, low-impact exercise can work the muscles without causing unnecessary tightness.
• Recommended Exercise: Downward-Facing Dog Pose
  • Performing each movement slowly for about 60 seconds is an effective way to improve flexibility.

3. For Fat Type

• Strategy: For those with excess calf fat, focusing on moderate aerobic exercise is recommended. It's also important to avoid excessive calorie intake and ensure adequate protein consumption. Rather than solely focusing on slimming your calves, sticking to a healthy, balanced diet will ultimately lead to a slimmer overall physique.
• Recommended Exercise: Jump Squats
  • This full-body exercise burns a significant number of calories, which is also effective for overall weight loss.
