Which of the following is an example of a static resistance exercise?

A plank is an example of a static resistance exercise because it requires the individual to maintain a specific position against resistance (in this case, gravity) without moving. During a plank, the muscles are engaged to hold the body in a straight line, which builds core strength and stability. This is different from dynamic exercises, where the muscles lengthen and shorten through movement, such as squats, deadlifts, and bench presses, which involve lifting or lowering weight through a range of motion. Static exercises like the plank focus on endurance and stabilization, making them an essential component of a well-rounded fitness program.
