Step 1
Identify the class of lever used in a bicep curl
Answer
When performing a bicep curl, the weightlifter is using a third class lever. In this lever system, the effort (muscle contraction) is applied between the load (weight) and the fulcrum (elbow joint). This configuration allows for a greater range of motion and speed of movement, making it ideal for exercises such as the bicep curl.
