9.2 Flexibility, Core, Balance, Reactive, and Resistance Technique

Key Takeaways Explain This Topic AI

NASM expects trainers to recognize proper setup and technique across flexibility, core, balance, reactive, and resistance training.

Technique is judged through the five kinetic-chain checkpoints, posture, control, tempo, breathing, and the client owning the range of motion.

Resistance training is built from fundamental movement patterns: squat, hip hinge, push (horizontal/vertical), pull (horizontal/vertical), and rotation/carry.

The major compound lifts (squat, deadlift, bench, overhead press, row) each have a defined setup, execution, and a short list of common faults to watch.

Reactive and balance drills require landing and alignment quality before height, speed, or instability are added.

Technique Across Integrated Training

NASM uses integrated training, so technique is not limited to barbell lifts. The exam can ask about a foam-roll position, a static stretch, a plank, a single-leg balance drill, a jump landing, a cable row, or a squat. The same coaching question sits underneath each: can the client perform the exercise with the intended muscles and joints controlling the task?

Start with the five kinetic-chain checkpoints . The foot/ankle should be stable for the task. Knees should track in line with the toes. The lumbo-pelvic-hip complex (LPHC) should avoid uncontrolled arching, rounding, or shifting. Shoulders should stay positioned for the movement. The head and cervical spine should avoid jutting, tilting, or excessive tension.

Modality Technique priority Common correction
Flexibility Target tissue without compensation or pain Adjust position, reduce pressure, slow breathing
Core Maintain spinal and pelvic control Shorten lever, reduce duration, cue draw-in/brace
Balance Keep checkpoint alignment while base of support changes Return to stable surface or bilateral stance
Reactive Land softly with knees aligned and trunk controlled Reduce height, speed, or volume
Resistance Move through controlled range under load Reduce load, range, tempo demand, or complexity

For flexibility work the target is not to force range. Self-myofascial techniques should be controlled. Static stretching should not create sharp pain or nerve symptoms. Core technique depends on category: a plank is not better because it lasts longer if the low back sags. Balance is tested through progressions — two-leg stable before unstable or single-leg variations; instability is useful only when it challenges control without destroying it. Reactive and plyometric drills magnify errors because force rises quickly; look for quiet, controlled landings with knees tracking over toes.

Resistance Exercise Categories and the Compound Lifts

NASM organizes resistance exercise around fundamental movement patterns rather than isolated body parts: squat, hip hinge, horizontal and vertical push, horizontal and vertical pull, and rotation/carry. A total-body session links these so that the kinetic chain works as a unit, while a body-part focus (chest/push, back/pull, shoulders, legs) selects exercises within one pattern. The major compound lifts each have a defined setup, execution, and fault list the exam expects you to recognize.

Lift (pattern) Primary muscles Setup → execution essentials

Back/front squat (squat) Quadriceps, glutes, hamstrings, erector spinae Feet shoulder-width, brace, knees track over toes, hips and knees flex together to depth, drive through mid-foot

Deadlift / RDL (hip hinge) Glutes, hamstrings, erectors, lats Bar over mid-foot, neutral spine, hinge at hips with soft knees, bar stays close, extend hips and knees together

Bench press (horizontal push) Pectoralis major, anterior deltoid, triceps Shoulder blades retracted/depressed, feet planted, slight arch, bar to mid-chest, press up and slightly back

Overhead press (vertical push) Anterior/medial deltoid, triceps, upper traps Brace core, bar/dumbbell at shoulders, press overhead without ribs flaring, lock out with bar over mid-foot

Bent-over / cable row (horizontal pull) Latissimus dorsi, rhomboids, mid-traps, biceps Hinge with neutral spine, shoulders down and back, pull elbows behind torso, squeeze shoulder blades

Common faults and fixes (fault → correction):

Common fault Fix

Squat: knee valgus (knees cave in) Cue knees out / track over toes; regress load; foam-roll adductors, activate glutes

Squat: heels rising or forward lean Improve ankle mobility, widen stance, reduce depth or load
Deadlift: lumbar rounding Stop the set, reduce load, reteach hip hinge with neutral spine
Bench: elbows flared 90 degrees, shoulders rolled forward Tuck elbows ~45 degrees, retract/depress scapulae

Overhead press: low-back hyperextension (ribs flare) Brace core, glute squeeze, reduce load or use half-kneeling press

Row: shoulder shrugging / upper-back rounding Cue shoulders down and back, slow tempo, lighter load

The exam often hides the answer in the word immediate . If a client rounds the low back during a deadlift, the immediate response is to stop the rep or set, reduce load, and reteach the hinge — the longer-term program may add mobility, core, or glute work. Technique is also specific to the person: a client with short legs may need a step under the feet on a bench press; a client with limited shoulder mobility may use a goblet squat instead of a back squat; a client with poor push-up control may use an incline push-up.

These are not easier by default; they are matched to current movement capacity. For study, connect every modality to one question: what is the most conservative change that keeps the training goal and restores control? That is the answer style NASM rewards.

Equipment Selection: Machine, Free Weight, Cable, and Body Weight

The exam also tests how the trainer chooses the tool, because the same pattern can be loaded with a machine, a free weight, a cable, or body weight, and each has trade-offs. Machines fix the movement path and provide built-in stability and safety stops, which makes them useful for beginners, for isolating a muscle, for high-fatigue states, or when a client needs to train safely without a spotter.

Free weights (barbells and dumbbells) demand the client stabilize the load through the full kinetic chain, which carries over well to daily movement and builds stabilization, but raises the skill and spotting requirement. Cables keep constant tension through the range and allow many angles and standing, integrated positions, making them strong choices for stabilization and functional work. Body-weight exercises are scalable through leverage, range, and surface, and require no external load — ideal for early progressions and home settings.

Tool Best fit Trade-off
Machine Beginners, isolation, safe high-fatigue work Less stabilizer demand, fixed path
Free weight Integrated strength, stabilization, carryover Higher skill and spotting need
Cable Constant tension, many angles, standing work Setup detail (height/handle) affects line of pull
Body weight Early progressions, home, scalable Hard to add precise load

A practical rule: match the tool to the client's stability and skill, the OPT phase, and the safety context. A deconditioned beginner in Phase 1 may use cables and machines plus body-weight stabilization work; a client building maximal strength may need free weights and a competent spotter. The trainer should never let the equipment dictate unsafe technique — if a cable height or machine seat forces a checkpoint out of line, adjust the setup or change tools before adding effort.
