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.
Need a proper exercise technic to improve your muscle mass.
not really. you just do more physical activities
Muscle strength
Muscle strength
The best would be physical therapy to increase the muscle strength.
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.
What muscle doesnt get used?
Muscle loss
Red Muscle is suited for endurance activities.
Cardiovascular workouts like running, swimming, biking, etc. They increase muscle and endurance as well as lowering your heart rate. You could also lift weights in addition to your cardiovascular workout. Hope it helps!
Press ups do increase chest muscle. When you're doing then it uses your pecks and the muscle above them.
How Much Physical Activity Do Youth Need? •Children and adolescents should do 60 minutes (1 hour) or more of physical activity daily 2 ■Aerobic Activities: Most of the 60 or more minutes per day should be either moderate- or vigorous-intensity aerobic physical activity. Vigorous-intensity physical activity should be included at least 3 days per week. ◦Examples of aerobic activities include bike riding, walking, running, dancing, and playing active games like tag, soccer, and basketball. ■ Muscle-strengthening Activities: Include muscle-strengthening physical activity on at least 3 days of the week as part of the 60 or more minutes. ◦ Examples of muscle-strengthening activities for younger children include gymnastics, playing on a jungle gym, and climbing a tree. ◦ Examples of muscle-strengthening activities for adolescents include push-ups, pull-ups, and weightlifting exercises. ■Bone-strengthening Activities: Include bone-strengthening physical activity on at least 3 days of the week as part of the 60 or more minutes. ◦ Examples of bone-strengthening activities include hopping, skipping, jumping, running, and sports like gymnastics, basketball, and tennis. •Some activities may address more than one category at a time. For example, gymnastics is both musclestrengthening and bone-strengthening while running is aerobic and bone-strengthening. •Activities should be age-appropriate, enjoyable, and offer variety
