The learner completes a provider-prescribed knee-extension set with every counted repetition meeting range and tempo, while muscle size, strength and function remain separate outcomes.
This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.
Complete bounded explanation
What this power means.
Capability to develop or express muscle hypertrophy and atrophy resistance in a declared context without inheriting broader claims.
What the current evidence supports
Muscle can grow with multiple resistance-training configurations, and some gains can be maintained with less training; exact needs differ by person and outcome.
How to observe or measure it without overclaiming
Imaging or fiber area measures size; one-repetition maximum measures task-specific strength. Neither alone establishes health or independence.
Myth
Build permanent muscle armor
Metric
Declared muscle size, strength and function over training and detraining
Boundary
Muscle size cannot prove permanent function or health.
Negative and limiting findings
Maintenance requirements differed between young and older adults and between strength and muscle-size outcomes.
Claims this evidence cannot support
Guaranteed muscle growth
Never lose muscle
Heavy is always best
Supplements replace training or food

How to learn this Power now.
The learner completes a provider-prescribed knee-extension set with every counted repetition meeting range and tempo, while muscle size, strength and function remain separate outcomes.
Get readyReport knee/hip/back pain, recent surgery, swelling, weakness, illness and unusual delayed soreness.

See right and wrong10 comparisons show correct or safer execution beside common wrong or riskier choices.
PractiseThe provider controls exercises, sets, repetitions, load, rest, weekly frequency and nutrition/clinical referral. Progress only when full-range controlled repetitions and recovery are stable; detraining and maintenance require separate plans.
Check progressUse a consistent validated imaging or circumference method for size, a separate standard strength test and a separate function; log training configuration and assistance. For muscle size, reproduce anatomical coordinate, side, body position, hydration/rest conditions, operator and imaging settings. Maintain separate exposure, strength and stair-function timelines. Assign quadriceps image-validity codes for landmark, plane, pressure, fascia visibility, depth and gain before tracing muscle boundaries.
Authority boundary: Titan teaches the complete method; a qualified person controls the parts that require supervision, clearance, specialist equipment, load, dose or progression. The method is Power-specific; its actionability follows this treatment.
Citation roles are explicit. A source may support existence or trainability while simultaneously limiting transfer, certainty, generalisation or safety.
