Busting the Myth: Optimal Range of Motion for Calf Muscle Growth Summary
- In fitness and bodybuilding, the optimal range of motion (i.e., full reps vs partial reps) for calf muscle growth performing calf raises has been extensively discussed and debated.
- Subjects performed calf raises for 8 weeks with either a full range of motion, the bottom portion of the calf raise only (i.e., stretched position), or the top range of motion (i.e., muscle contraction at the top).
- The study found that partial ROM training at the bottom was more effective than full ROM training for calf muscle hypertrophy. However, there was no significant increase in muscle thickness for the FINAL ROM configuration.
Introduction to the Gastrocnemius and Soleus
The gastrocnemius and soleus muscles, collectively known as the calf muscle group, are responsible for plantar flexion at the ankle joint. This movement occurs when you push off the balls of your feet, such as during jumping or while performing lower-body exercises like squats and deadlifts. To stimulate calf muscle growth effectively, it’s important to understand the range of motion required for targeting these muscles.
The conventional wisdom among fitness enthusiasts and bodybuilders has long been that performing exercises, such as standing calf raises, with a full range of motion, is crucial to stimulate maximum muscle growth. However, a groundbreaking study titled “Greater Gastrocnemius Muscle Hypertrophy After Partial Range of Motion Training Performed at Long Muscle Lengths” challenges this long-standing notion, mainly focusing on calf muscle development.(Kassiano et al., 2023)
Additionally, other studies have challenged a full range of motion dogma, suggesting that partial ROM training can elicit favorable improvements in strength and muscle mass, even when carried out at long muscle lengths (i.e., stretched positions). (Pedrosa et al., 2021) This article delves into this study and others to shed light on the optimal range of motion for calf muscle growth. It provides insights and advice for fitness enthusiasts and bodybuilders seeking to maximize their gains.
The Prevailing Belief: Full Range of Motion is Essential
Many believe that a full range of motion is necessary for optimal calf muscle growth. However, it is important to examine the misconceptions surrounding this prevailing belief. While it is true that the gastrocnemius and soleus muscles, which make up the calf muscle group, are involved in lower body movements such as walking, jumping, and running, the idea that a full range of motion is essential may not necessarily hold true.
Traditionally, a full range of motion in exercises like standing calf raises is crucial to stimulate muscle fibers effectively and induce significant muscle growth. This belief is grounded in the idea that a full range of motion leads to a more substantial stretch and contraction of the muscle, promoting enhanced muscle development.
A 2021 study investigated the effects of partial ROM training at long muscle lengths on muscular growth in the legs. The researchers found that partial ROM training in the initial phase of the leg extension exercise promoted greater relative hypertrophy in certain muscle regions compared to training a full range of motion. Interestingly, the group that performed partial ROM training at long muscle lengths showed similar increases in strength and muscle growth compared to the full range of motion. (Pedrosa et al., 2021).
Furthermore, a 2022 review found no differences between the full range of motion and partial range of motion interventions for muscle hypertrophy. This suggests that full and partial ROM training can lead to muscle hypertrophy.(Kassiano et al., 2022) This revelation is pivotal as it indicates that the optimal range of motion for calf muscle growth may not necessarily involve moving through a complete range of motion.
Scientific Backing: Studies Supporting Partial Range of Motion
A research piece focusing on long-muscle length training benefits found that training muscles at longer lengths can lead to significant hypertrophy, even with a partial range of motion. The review included various studies that compared full ROM and partial ROM resistance training interventions. The meta-analysis results showed no significant differences between full and partial ROM interventions regarding changes in muscle hypertrophy. This further supports the notion that both full and partial ROM training can lead to muscle hypertrophy.(Pallarés et al., 2021)
Potential Mechanisms for Optimal Range of Motion
Newmire & Willoughby briefly reviewed the potential mechanisms underlying the effects of partial ROM resistance training on muscle hypertrophy. The authors discussed factors such as muscle activation and mechanical tension, which may contribute to muscle growth during partial ROM training. They concluded that partial ROM training can be an effective strategy for muscle hypertrophy and should not be overlooked. (Newmire & Willoughby, 2018)
Training at Long Muscle Lengths Training Benefits
A recent investigated the effects of different ranges of motion (ROM) on calf muscle hypertrophy. The study involved training sessions consisting of 3 sets of 15-20 repetitions maximum in the calf raise exercise.
The subjects were assessed before and after the training program for muscle hypertrophy. The training frequency for all experimental groups in the study was 3 times a week. This means that the subjects trained three times per week for 8 weeks, with each training session consisting of 3 sets of 15-20 repetitions maximum in the calf raise exercise. In total, there were 24 training sessions throughout the study.
Optimal Range of Motion for Calf Muscle Growth: Study Design
The study consisted of three groups: FULL ROM, INITIAL ROM, and FINAL ROM. These groups were used to compare the effects of different range of motion configurations on gastrocnemius muscle thickness.
- The FULL ROM group performed the exercise through the full range of motion.
- The INITIAL ROM group focused on the initial part of the range of motion (stretched calf raise) and
- The FINAL ROM group focused on the final part of the range of motion. (i.e., contracted muscle at the top).

Optimal Range of Motion for Calf Muscle Growth Results
The study found that both the FULL ROM and partial ROM configurations (INITIAL ROM and FINAL ROM) resulted in increased hypertrophy of the gastrocnemius muscles. However, the INITIAL ROM group achieved greater increases in muscle growth compared to the other two configurations. These findings suggest that performing calf raise exercises with partial ROM in the movement’s initial portion may induce greater gastrocnemius muscle hypertrophy.(Kassiano et al., 2023)
Implications for Training: How Many Reps Calf Raises?
The answer may not be straightforward for those wondering how many reps of calf raises are optimal. The key is to focus on the quality of the reps and the muscle stretch rather than the quantity or the range of motion. Incorporating a mix of full and partial range of motion exercises in your calf workout routine can lead to better muscle growth and development.
Optimal Range of Motion for Calf Muscle Growth Conclusions
In conclusion, the belief that full range of motion is essential for calf muscle growth is a myth. Scientific studies have shown that training at long muscle lengths can provide significant benefits for calf growth. It is important to understand the potential mechanisms behind optimal range of motion and how it can impact your training. When it comes to calf raises, the number of reps will depend on your specific goals and abilities. It is recommended to consult with a fitness professional to determine the optimal range of motion and training regimen for your calf growth journey. Remember, consistency and proper form are key to achieving optimal results.
