There are many exercises you could do for small muscle groups such as smiling. You could also do butt flexes.
The same way as for any other age group . By exercise and diet.
Good to exercise daily but if you do resistence training give each muscle group 48 hours before using it again.
Primarily the lower chest muscles
The Front Curl works with the biceps.
Usually the heaviest weight you can do 8-10 reps at an exercise, ending with fatigue of the muscle group. Generally three sets per exercise.
how can an exercise be over-hyped? it works out a specific muscle group and if you are looking to focus on that group of muscles then its a good exercise. but you wouldnt do military presses if you were looking to improve your squat strength.
Many people work out every day. The best thing to do is to exercise one muscle group one day, and another the next day. That way the first muscle group gets time to rest.
Compound exercise is the exercise which involves more than one joint and muscle group. For example squat involves the joints of knees, hip, ankle and the muscles of the upper and lower legs and buttocks.
Eccentric exercises are not a separate kind of exercise. Rather, each resistance exercise has two phases. (1) The concentric phase is when the muscle group being trained is shortened, for example, when you raise a barbell doing a standing curl. (2) The eccentric phases is when the muscle group being trained is lengthened, for example, when you lower a barbell doing a standing curl to its original position.
During exercise muscle cells use oxygen.
Open chain exercises work with a single muscle group and joint whereas closed chain exercises work with multiple muscle groups and joints.
