How the Calf Builder Can Engage the Soleus & Gastrocnemius Muscles
Understanding calf biomechanics can help you train the muscles safely and effectively. The Calf Builder, with its push-down pedal design, is designed to allow users to target both the soleus and gastrocnemius muscles during seated and standing movements. This design provides a controlled way to engage the calves while reducing reliance on other muscles.
The Soleus vs. Gastrocnemius: What’s the Difference?
Your calf is made up of two primary muscles:
Gastrocnemius – The larger, more visible muscle that contributes to the shape of your calves. It is generally more active during standing movements with straight legs.
Soleus – Located beneath the gastrocnemius, the soleus contributes to endurance and stability. It is typically more engaged when the knees are bent, as in seated calf raises.
Different exercises can engage these muscles in varying amounts. Traditional calf exercises, like standing or seated calf raises, may place more emphasis on one muscle than the other depending on knee angle.
The Push-Down Pedal Advantage
The Calf Builder uses a push-down pedal mechanism to mimic a pedal-press motion. This design offers several features:
Consistent Muscle Engagement – The controlled single-plane motion helps users maintain tension on both the soleus and gastrocnemius throughout the movement.
Balanced Activation of Calf Muscles – The seated position allows users to focus on their calves, supporting consistent engagement of both muscles.
Suitable for Rehabilitation and Controlled Training – The smooth motion can support users looking to work on ankle mobility or lower-leg strength safely and in a controlled manner.
Research-Backed Considerations of Push-Down Motion
Studies on exercises such as the “soleus push-up” and cycling—which mimic a push-down pedal motion—have shown these movements can engage both the soleus and gastrocnemius muscles. Removing the need for foot rotation or balancing can help maintain consistent calf engagement throughout each repetition. While results may vary for each individual, these exercises illustrate how controlled, single-plane motions can be useful for focused calf training.
Why Use the Calf Builder?
The Calf Builder is designed to provide controlled resistance and a comfortable motion for calf training:
Consistent Resistance – Its pulley mechanism maintains tension throughout the movement.
Ergonomic Design – The push-down pedal motion reduces strain on the feet and joints.
Focused Calf Engagement – Allows users to target the soleus and gastrocnemius while reducing involvement of other muscles.
Build Calf Strength Safely
Whether your goal is to support lower-leg strength, maintain mobility, or supplement rehabilitation exercises, the Calf Builder offers a compact and user-friendly option for home training. Users can control weight and movement to suit their own abilities and training preferences.

Note: The following studies illustrate how certain calf exercises engage the soleus and gastrocnemius muscles. Results may vary depending on individual use and training conditions.
1. Muscle Activation during Calf Raises and Other Exercises
- Study: "Muscle activation during standing and seated calf raises"
Journal: Journal of Strength and Conditioning Research
This study investigates the muscle activation of the gastrocnemius and soleus during various calf raise exercises, showing how different knee angles (bent or straight) activate the soleus and gastrocnemius differently.
2. Effect of Knee Angle on Soleus and Gastrocnemius Activation
- Study: "Effect of knee joint position on gastrocnemius and soleus muscle activation during plantarflexion"
Journal: Journal of Electromyography and Kinesiology
This research shows how the knee position significantly alters the activation levels of the gastrocnemius and soleus, explaining why seated calf raises (with a bent knee) engage the soleus more effectively than standing calf raises.
3. Cycling and Pedal Mechanisms for Calf Muscle Engagement
- Study: "Muscle activation and exercise intensity of cycling versus running on calf strength"
Journal: European Journal of Applied Physiology
This study compares cycling with other lower-body exercises and assesses how the push-pedal action of cycling engages both the gastrocnemius and soleus muscles.
4. Soleus Push-Up and its Benefits for Calf Strength
- Study: "The effect of the soleus push-up on calf muscle strength and endurance"
Journal: Journal of Sports Science & Medicine
This study examines how exercises targeting the soleus, like the soleus push-up, help activate the muscle without engaging the gastrocnemius as intensely.
5. Biomechanics of Pedal-like Movements
- Study: "Biomechanical effects of pedal-like movements on lower limb muscle activation"
Journal: Journal of Biomechanics
This study discusses how pedal-like motions, such as those used in cycling or similar push-down actions, engage both the soleus and gastrocnemius muscles effectively through the range of motion.
