Which of the following is a Pilates exercise listed in the standard families?

• A. Spinal Extension
• B. Balance and Coordination Training
• C. The Hundred
• D. Weight Bearing

Answer: (C)

The main idea here is identifying a classic Pilates mat exercise that appears in the standardized repertoire. The Hundred is that foundational move in Pilates mat work and is consistently listed in Balanced Body’s standard exercise sets. It combines coordinated breathing with deliberate abdominal engagement and a controlled arm and leg rhythm while the pelvis remains stable and the torso stays lifted. This pairing of breath with core control is central to Pilates practice and is what makes The Hundred a quintessential item in the standard families.

Spinal Extension is a general back-extension movement rather than a named standard exercise, and Balance and Coordination Training and Weight Bearing describe goals or loading concepts rather than specific Pilates moves.
