Physical educators share valuable insights into the muscle groups that often challenge bodybuilders, including the triceps (on the arm), the inner thighs and the calf.
These three muscles are notorious for their tendency to resist growth. Experts attribute this to the unique fibrous composition of these regions of the body.
“The triceps (arms), inner thighs and calves will never grow as quickly as other muscle groups. The fibers they have are different”, explains personal trainer Carlos Bruce.
Importantly, personal genetics and individual body composition also play significant roles in muscle development.
Personal trainer Caio Signoretti emphasizes that the tendency towards hypertrophy varies from person to person, regardless of the training.
Differentiation in muscle fiber types also impacts muscle growth. Muscles can be classified as slow (with reddish fibers), fast (with whitish fibers) and mixed.

The calves and inner thighs are examples of mixed muscles, while the triceps are predominantly made up of fast muscle fibers. Such a composition makes them more susceptible to fatigue during exercise.
Furthermore, these muscle groups are not widely involved in everyday activities, which makes their growth even more difficult.

However, professionals in the field guarantee that training focused on these muscle groups is capable of overcoming natural difficulties.
It is possible to train them and include activities in daily life that increase their use. For the calves, for example, standing on tiptoe and climbing stairs are examples of great trainings. For the inner thighs, exercises that involve squeezing objects work well.
As for the triceps, the ideal is to do movements that extend the elbows by pushing heavy objects or doing push-ups. This is the advice from specialist Guilherme Camargo.
Therefore, patience and dedication to targeted exercises are essential to overcome challenges in the quest to develop these “stubborn” muscles.
With the right guidance and perseverance, it is possible to achieve satisfactory results and achieve the desired muscular balance.
