National Academy of Sports Medicine (NASM) Group Fitness Instructor Practice Exam

Which exercise is contraindicated in the group fitness setting?

1. Straight leg deadlifts

2. Bodyweight squats

3. Push-ups

4. Jumping jacks

The correct answer is: Straight leg deadlifts

In a group fitness setting, contraindicated exercises are those that pose a higher risk of injury or are generally not suitable for a diverse class audience. Straight leg deadlifts can be particularly problematic, especially when performed without proper supervision or individualized modifications. This exercise places significant strain on the lower back and hamstrings and requires a high level of flexibility and strength to execute correctly. Beginners or individuals with pre-existing injuries may struggle with the technique, increasing the likelihood of injury. On the other hand, bodyweight squats, push-ups, and jumping jacks are foundational movements that can be adapted to various fitness levels. Bodyweight squats primarily target the lower body and can be modified for depth and support. Push-ups can cater to different abilities by adjusting hand placement or elevating the upper body. Jumping jacks offer cardiovascular benefits and can also be modified by reducing impact, making them suitable for a wider audience. This adaptability and lower risk of injury associated with the other exercises make straight leg deadlifts less appropriate for a diverse group fitness class.
