A contraindicated exercise is best defined as

• A. An exercise that stretches only a single muscle group
• B. An exercise performed with proper form
• C. An exercise not suitable for most people since risk is greater than reward
• D. An exercise that improves endurance for all individuals

Answer: (C)

Contraindicated exercises are not recommended for most people because the risk of adverse effects outweighs the potential benefits. They may worsen an existing condition, aggravate an injury, or pose a danger given certain health factors, so they’re avoided unless medical clearance or safe modification is provided. The other statements describe conditions that are generally safe, beneficial, or neutral to safety—such as exercising with proper form or targeting endurance—rather than being unsafe. Therefore, the best definition is that an contraindicated exercise isn’t suitable for most people because the risk is greater than the reward.
