Final Answer:
The spotter should place their hands under the lifter's elbow during the DB Bench Press(1) and DB Flys(3) ,So, the correct ption is 4.
Step-by-step explanation:
In the DB Bench Press, the spotter placing hands under the lifter's elbow provides crucial support and stability during the lifting phase. This hand positioning helps ensure that the lifter maintains proper form, reducing the risk of injury and allowing for a more controlled movement. By supporting the lifter's elbows, the spotter can assist with the lift while allowing the lifter to exert force primarily through their chest muscles.
Similarly, during DB Flys, placing hands under the lifter's elbow is essential for safety and effectiveness. DB Flys involve a wide range of motion where the lifter extends their arms horizontally. The spotter's hands under the elbows provide support, especially during the lowering phase, preventing excessive strain on the shoulder joints. This support enables the lifter to focus on targeting their chest muscles without compromising form.
For exercises like the Arnold Press (2), the lifter's arms move in a rotational and pressing motion rather than a horizontal extension. In this case, the spotter typically provides support by monitoring the weights and assisting if the lifter struggles, but placing hands under the elbows may not be as critical as in exercises with a horizontal component.
In summary, the correct answer is option 4 (A and C), as the spotter should place their hands under the lifter's elbow during the DB Bench Press and DB Flys for optimal support and safety.
