Exercisability refers to an individual’s ability to perform physical activity safely and effectively based on their fitness level, health status, and physiological capacity. It reflects how well the body can tolerate exercise, adapt to workload, and recover afterward. Factors such as cardiovascular function, muscle strength, mobility, motivation, and medical conditions influence exercisability, making it an important measure in training, rehabilitation, and overall health ass

Shoulder pain is discomfort or soreness around the shoulder joint, caused by injury, inflammation, overuse, or underlying conditions. It may result from rotator cuff strain, tendonitis, bursitis, arthritis, or nerve impingement. Pain can limit motion, strength, and daily activities. Proper diagnosis and treatment, including rest, physical therapy, or medical care, are essential for recovery and prevention of further damage.

The agonist-antagonist ratio describes the balance of strength or activation between opposing muscle groups during movement, such as quadriceps versus hamstrings. A healthy ratio supports joint stability, control, and performance, while imbalances can increase the risk of injury or limit movement efficiency. This ratio is often assessed in rehabilitation and sports science to guide training, restore balance, and optimize muscular coordination and function.

Weightlifting is a strength-focused exercise that uses resistance, often with barbells or dumbbells, to build muscle, power, and endurance. It improves bone health, metabolism, and overall fitness while supporting athletic performance. Proper technique and progressive overload are key for safety and results. Weightlifting is adaptable for all levels, helping individuals achieve goals from strength and muscle growth to fat loss and functional health, making it a cornerstone of
