Two things could be the cause, one is you are not pushing yourself hard enough.
But most likely it is because you are not eating the right things to give you muscles what they need to get larger.
and also, dont always assume that just because your muscles arn't getting bigger, doesnt mean they arnt getting stronger.
Engaging in strength training helps to build muscle mass and increase strength by causing muscle fibers to adapt and grow stronger. This leads to improved physical fitness, as stronger muscles can perform better during physical activities and help prevent injuries. Additionally, strength training can increase metabolism, improve bone density, and enhance overall body composition.
not really. you just do more physical activities
Muscle strength
An increase in myoglobin stores means there is more oxygen-binding protein available in muscle tissues. This can improve the muscles' ability to store and utilize oxygen, leading to better endurance and performance during physical activities.
Some effective muscle-strengthening activities include weightlifting, bodyweight exercises like push-ups and squats, resistance band workouts, and activities like yoga and Pilates. These exercises can help improve muscle strength, endurance, and overall physical fitness.

Yes, animals can build muscle through exercise and physical activity. Just like humans, animals can increase muscle mass and strength by engaging in regular physical activity and exercise.
Muscle strength
The best would be physical therapy to increase the muscle strength.
Wearing Skins compression clothing during physical activities can help improve circulation, reduce muscle fatigue, enhance performance, and aid in recovery by providing support to muscles and reducing muscle vibration.
Nearly all physically activities increase muscle mass overtime, but strength training activities such as weightlifting are obviously the most effective. The muscle fibers are slightly torn by lifting, as they re-grow with the aid of protein, they become bigger and stronger, this is called hypertrophy.
Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the heart if summation occurred the contractions would keep increasing.
