Exercise Technique and Instruction Flashcards

A personal trainer observes a client's hips rising faster than their chest during the initial pull of a conventional deadlift. This form deviation places the most significant stress on which part of the body?

Answer: The lumbar spine

When the hips rise prematurely in a deadlift, the lifter's torso becomes more horizontal, forcing the lumbar spine extensors to bear a much greater portion of the load to lift the bar. This turns the movement into more of a 'stiff-leg' deadlift, significantly increasing the shear stress on the lower back and the risk of injury.

When spotting a client during a barbell bench press, what is the most appropriate grip for the spotter to use on the bar during the lift-off and when assistance is needed?

Answer: An alternated (mixed) grip inside the client's hands

An alternated, or mixed, grip (one hand pronated, one supinated) provides the most secure hold on the barbell, preventing it from rolling out of the spotter's hands. The hands should be placed inside the client's grip to ensure proper leverage and control when assisting or racking the weight.

A client is performing a kettlebell swing, but the trainer notices they are using their arms to lift the bell and finishing in a squat-like position. Which cue would be most effective to correct this movement pattern?

Answer: "Hinge at the hips like you're trying to shut a car door with your glutes."

The kettlebell swing is a hip-hinge movement, not a squat. The cue to "hinge at the hips like you're trying to shut a car door with your glutes" effectively teaches the client to initiate the movement by pushing their hips back, loading the posterior chain (glutes and hamstrings), which should be the primary power source for the swing.

Which of the following scenarios is a contraindication for performing high-intensity plyometric exercises?

Answer: A client who is experiencing acute joint inflammation.

Plyometric exercises involve high-impact, explosive movements that can exacerbate existing medical conditions. Acute joint inflammation is a direct contraindication, as the high forces generated during plyometrics could increase pain, swelling, and potentially cause further damage to the joint.

During a squat assessment, a trainer provides the cue, "Imagine you are spreading the floor apart with your feet." What is the primary purpose of this instructional cue?

Answer: To promote external rotation of the hips and activate the glutes

The cue to "spread the floor apart" or "screw your feet into the floor" encourages the client to create torque at the hip joint. This action facilitates external rotation, which helps to activate the gluteus medius and other hip abductors. This activation prevents knee valgus (knees caving inward) and creates a more stable and powerful squat.

A trainer is guiding a client through a Proprioceptive Neuromuscular Facilitation (PNF) hamstring stretch using the 'hold-relax' technique. What is the correct sequence of actions?

Answer: A 10-second passive stretch, followed by a 6-10 second isometric contraction of the hamstring, then a deeper passive stretch.

The 'hold-relax' PNF technique involves moving the muscle into a passive stretch and holding it (e.g., for 10 seconds). The client then performs an isometric contraction of the stretched muscle (the hamstring) against the trainer's resistance for about 6-10 seconds. Following the contraction, the client relaxes, and the trainer moves the limb into a deeper passive stretch for 20-30 seconds.
