Your muscular strength will depend on many things but the most important elements are your muscle fivers and the ability of nerves to activate muscle fibres and they will decide how much muscular strength you have.
Even though it may seem that muscular strength is nothing but how strong you are, that may not be true. It does not mean your weight, how much weight you can lift at the gym, how hard you can punch etc. American Council on Exercise (ACE) describes muscular strength as the maximal force a muscle or muscle group can exert during a contraction. It is measured with a one-rep maximum (1-RM) test.
Muscular strength will also depend on how strong you are and how much strength you have while doing anything. It will depend on muscular endurance and muscular power. Muscular endurance is the ability of your muscles to exert force against resistance during a specific period. Muscular powers is a combination of muscular force and the speed of movement.
