Which activity is primarily driven by large muscle groups and constitutes a gross motor skill?

• A. Jumping
• B. Coloring
• C. Running
• D. Hurdling

Answer: (A)

Gross motor skills involve the large muscles that move the body. Jumping is a prime example because it relies on a powerful, coordinated effort from the legs and core to push off the ground and then stabilize on landing. The major muscles at work include the quadriceps, hamstrings, glutes, calves, and core, all coordinating to produce that explosive upward movement.

Coloring, in contrast, uses fine motor control—smaller muscles in the hands and fingers for precise, controlled movements. Running and hurdling are also gross motor activities, but jumping best fits the description of a single, explosive action driven primarily by large muscle groups.
