Exercise Technique and Training Instruction

Domain 4 - Exercise Technique and Training Instruction

This domain tests whether you can set up, cue, and progress exercises safely, and whether your instruction matches the intended adaptation. Expect questions on hip-hinge mechanics, spinal position during rotation, and effective cueing.

Core rules

  • Hinge: hips back, neutral spine, load through the mid-foot, and drive with glutes and hamstrings. Do not turn a hinge into a squat.
  • Rotation: rotate through the thoracic spine and hips while keeping the lumbar spine stable; avoid loaded flexion combined with rotation.
  • Anti-rotation resists motion, as in Pallof press; rotation produces motion, as in chop and lift; rotary power throws a medicine ball.
  • Cue simply: one cue at a time. Use external cues such as “push the floor away” or internal cues such as “ribs down” when needed.
  • Progress one variable at a time: range, reps, load, or speed. Regress to half-kneeling or supported positions when control is lost.
  • Safety: neutral spine, controlled tempo, no ballistic stretching before power work, and screen for pain.

Worked example

Kettlebell swing for power. Setup with feet shoulder-width and the bell in front. Hinge and hike the bell back, then snap the hips forward so the bell floats to chest height. Do not squat-lift or hyperextend the lumbar spine. Cue “hips back, then stand tall and squeeze the glutes.” If the client loses a neutral spine, regress to a dowel hip hinge and reduce load.

Traps

  • Cueing “rotate your low back” during chops.
  • Adding speed before the hinge and anti-rotation are mastered.
  • Giving too many cues at once so the client cannot process them.
