Underdeveloped muscles are a common issue, especially for athletes. There are over 600 muscles in the human body, and many of them are small and don't significantly affect sports performance and orthopedic health. However, neglecting certain muscles can lead to imbalances, decreased performance, and injuries. For example, weak glutes are a common issue due to sitting all day, which can lead to back pain and injury. Similarly, tight hip flexors and neck muscles can cause weak muscles on the other side of the joint, a condition called Arthrokinetic Dysfunction. Additionally, underdeveloped shin muscles can increase the risk of knee injuries. To prevent these issues, it's important to focus on a diverse range of exercises that target different muscle groups and maintain a balanced fitness routine with adequate recovery time.

What You'll Learn
Muscle atrophy
Disuse atrophy can begin within two to three weeks of muscle disuse and is often seen during periods of immobilisation due to injury or illness. The hallmark sign of muscle atrophy is the loss of lean muscle mass, which can be challenging to detect in individuals with obesity or significant fat mass changes. The predominant symptom is increased muscle weakness, which can lead to difficulty performing everyday physical tasks. Atrophy of core or leg muscles may cause issues with standing from a seated position, walking, or climbing stairs, increasing the risk of falls. Throat muscle atrophy can cause difficulty swallowing, while diaphragm atrophy can lead to breathing difficulties.
The treatment of muscle atrophy depends on the underlying cause and may include exercise, physical therapy, ultrasound therapy, and in some cases, surgery. Anabolic agents may also be considered, although they are not frequently used due to potential side effects. Minimising immobility during injury or illness is critical to preventing muscle atrophy. Additionally, maintaining adequate nutrition is essential, especially in cases of malnutrition, where nutritional therapy can help reverse muscle atrophy.
While muscle atrophy can have various causes and present with different symptoms, it is essential to seek medical advice for a proper diagnosis and treatment plan. A healthcare provider will typically perform a physical examination, assess symptoms, and may recommend further tests to determine the extent and cause of the atrophy.

Training methods
Glutes
The glutes are a group of three muscles: the gluteus maximus, gluteus medius, and gluteus minimus. They are essential for proper biomechanics and athletic performance, as well as being connected to the spine. Weak glutes can lead to back pain and injury. To strengthen the glutes, it is recommended to perform exercises that engage the posterior deltoids and glutes, such as deep squats, bent-over rows, and Aussie pull-ups. Another exercise is to use a heavy resistance tubing circle, stepping inside with both feet and fastening it around each ankle. Stand with a wide sports stance, knees slightly bent, and perform side shuffles or lateral lunges.
Core
The core consists of abdominals, obliques, and the lower back. To train the core effectively, it is recommended to perform exercises that engage all three regions simultaneously. For example, for every crunch, do a side bend and a lower back extension. Holding planks while drawing in your belly button is also an excellent way to engage the entire core.
Neck
The deep neck flexors are often weak and underdeveloped, which can lead to neck pain. To strengthen these muscles, progressive overload exercises such as weighted neck flexions are recommended.
Forearms
The forearm flexors are important for gripping heavy objects, and weak forearm flexors can hamper your ability to train larger muscles. To strengthen them, try simple exercises like squeezing and releasing a tennis ball while watching TV, or tying a light weight to a rope and rolling it up and down by rotating your wrists.
Rotator Cuff
The rotator cuff is a group of four muscles that stabilize the shoulder joint. To keep them strong and prevent injuries and pain, it is important to take a proactive 'pre-hab' approach. One exercise to strengthen the rotator cuff is to attach light to medium resistance tubing to a door hinge, stand with your left side to it, and rotate your arm at the elbow, pulling the tubing.
Back
The erector spinae is a bundle of muscles and tendons that extend throughout the lower, mid, and upper back. Weak spinal erectors can lead to back pain and sports injuries. To strengthen them, try back extensions: lie face down over a back extension machine with anchored heels, and slowly raise your torso until your body forms a straight line.
Shin
The tibialis anterior is an important muscle that controls the ankle joint, which is key when walking or running. Training this muscle can help prevent injuries like shin splints. To strengthen the tibialis anterior, perform exercises that work the front of the shin, such as standing calf raises.
Serratus Anterior
The serratus anterior is a small but important muscle that prevents the shoulder blade from tilting forward excessively. To strengthen this muscle, specific and subtle exercises are required, which is why it is often neglected.
Pelvic Floor
The pelvic floor muscles work with the TVA and multifidi to produce spinal stability. These muscles are small and produce small movements, but they can be strengthened with proper instruction and training, which is beneficial for athletes and individuals with low back pain.
Overall Recommendations
To address underdeveloped muscles, it is important to incorporate a variety of training methods, including strength training, cardiovascular exercise, mobility work, and flexibility training. Additionally, ensure you are using proper form during exercises and addressing any muscle imbalances. Foam rolling and stretching are also important components of a well-rounded training program, helping to alleviate muscle tightness and improve mobility.

Muscular imbalance
Muscles on either side of the joints and bones need to be equally strong and flexible to properly carry out movements. When there is a muscular imbalance, the body compensates by using other muscles and joints, which can lead to increased stress on joints and tendons, muscle tension, poor posture, limited mobility, pain, and an unbalanced gait or appearance. This can result in serious injuries, especially in sports, where muscular imbalances can lower performance.
To prevent and correct muscular imbalances, it is important to incorporate a variety of exercises that target different muscle groups and to avoid repeatedly performing the same movements. Additionally, addressing muscular imbalances can improve muscle strength and enhance the range of movement.

Common neglected muscles
There are over 600 muscles in the human body, and while some are too small to significantly affect sports performance, most do play a role in some way. Here are some of the most commonly neglected muscles:
Glutes
The glutes are a group of three muscles: the Gluteus Maximus, Gluteus Medius, and Gluteus Minimus. The Gluteus Maximus is one of the largest and strongest muscles in the body, helping us to get up from sitting, jump, lift heavy objects, and climb stairs. When this muscle is neglected, other muscles have to work harder, and joints absorb extra wear and tear, which can lead to back pain and injury.
Erector Spinae
This is a bundle of muscles and tendons that extend throughout the lower, mid, and upper back. Weak spinal erectors can lead to poor posture and back pain.
Rotator Cuff
The rotator cuff is a group of four muscles that stabilize the shoulder joint. If you injure your rotator cuff, you will restrict your range of motion, making overhead movements painful.
Tibialis Anterior
This muscle runs along the bottom part of your leg, next to your shin bone. Its primary function is dorsiflexion (pulling the foot upward toward the ankle), and it also helps to stabilize the ankle and balance the leg. Neglecting this muscle can lead to shin splints and other lower-leg pains.
Brachialis
The brachialis lies underneath the biceps and is visible on the outside of each upper arm. It works with the biceps as a flexor of the elbow joint. Training this muscle can add width to your arms and create a more impressive appearance when the biceps are flexed.
Extensor Muscles
These muscles lie on the top of each forearm and are responsible for moving the top of the hand backward toward the wrist. They are often neglected, even by bodybuilders, who tend to only work the wrist flexors and not the extensors. Training these muscles can assist your grip in other lifts.
Core Muscles
The core consists of three regions: abdominals, obliques, and the lower back. It is important to work all three regions equally to maintain balance and stability.
Many common injuries, such as pulled hamstrings, lower back pain, knee pain, and muscle tears, can be prevented by paying attention to these often-neglected muscle groups and incorporating targeted exercises into your fitness routine.

Prevention and treatment
Underdeveloped muscles can be prevented and treated through a variety of exercises, including strength training, cardiovascular exercise, mobility and flexibility work, and functional training.
To prevent underdeveloped muscles, it is important to choose exercises that are suitable for your body type and fitness goals. Your workout program should include a balance of exercises, diversity in the types of exercises, and adequate recovery time. For example, for every push exercise, perform a pull exercise, and for every bench press, do a bent-over row. Additionally, deep squats are preferable to leg presses as they engage the glutes more effectively.
SMR (self-myofascial release) techniques, such as using foam rollers, can also help to alleviate muscle tightness. To be effective, SMR should be performed daily, holding in sensitive areas for 20 to 30 seconds. Static and dynamic stretching are also important components of preventing and treating underdeveloped muscles. Static stretching involves holding each stretch for 15 to 30 seconds and should be performed after workouts. Dynamic stretching involves sport-specific movements and should be performed prior to your workout to prepare your body for activity. Aim to stretch five to seven times a week.
To improve core strength and prevent underdeveloped abdominal muscles, it is recommended to perform a 1-1-1 ratio of crunches to side bends to lower back extensions. Holding planks for 10 to 15 seconds while drawing in your belly button is another effective core exercise.
Additionally, certain muscle groups are commonly neglected, which can lead to pain and injury. For example, the glutes are often underactive, which can result in back pain and injury. The rotator cuff is another commonly neglected muscle group, as weightlifters and athletes tend to focus on larger, more visible muscles. Neglecting the rotator cuff can lead to issues with the shoulder joint.
Overall, a well-rounded exercise program that targets multiple muscle groups and includes stretching and foam rolling can help prevent and treat underdeveloped muscles.
