Symbols of strength are often used to represent power and resilience. OXEN, oaktrees, OAKS, and FISTS are all symbols of strength. OXEN are animals that are often used for labor and transportation, and their strength is often seen as a symbol of hard work and determination. Oaktrees and OAKS are both symbols of strength due to their longevity and durability. FISTS are also a symbol of strength, representing physical power and the ability to defend oneself.
