Resistance Training Variables
Key Takeaways
Volume (sets × reps), intensity (%1RM or RPE), and frequency determine hypertrophy and strength outcomes.
Strength emphasis: 1–6 reps, ≥85% 1RM, long rest; hypertrophy: 6–12 reps, 65–85%, moderate rest.
Tempo notation (e.g., 3-1-1-0) controls time under tension and eccentric stress.
Rest intervals: 2–5 min strength, 30–90 sec hypertrophy, 30 sec or less endurance circuits.
Exercise order: power/explosive first, then compound, then isolation; alternate push/pull when pairing.
Resistance Training Variables
Quick Answer: Match reps and load to goals: low reps/heavy for strength, moderate reps for hypertrophy, high reps for endurance. Order exercises power → compound → isolation. Manipulate volume, intensity, rest, and tempo for progressive overload. # Resistance Training Variables Resistance training variables are the knobs CPTs turn daily. NCCPT scenarios give client goals and training history—select the variable adjustment that best fits evidence and safety.
Repetition Continuum
| Goal | Reps | %1RM | Rest |
|---|---|---|---|
| Strength | 1–6 | 85–100% | 2–5 min |
| Hypertrophy | 6–12 | 65–85% | 60–90 sec |
| Muscular endurance | 12–20+ | <65% | 30–60 sec |
| Power | 1–5 explosive | 30–60% or bodyweight | 2–5 min |
Overlap exists—hypertrophy occurs across wide rep ranges if sets approach failure and volume sufficient.
Volume Landmarks
Weekly sets per muscle group:
- Maintenance: ~6–8 hard sets
- Growth: ~10–20 sets (intermediate)
- Advanced: may exceed 20 with periodization
Count hard sets near failure (0–3 RIR). Junk volume with poor form does not count.
Tempo and Time Under Tension
Notation E-P-C-P (eccentric-pause-concentric-pause). 3-1-1-0 = 3 sec lower, 1 sec pause, 1 sec lift, no pause top. Slower eccentrics increase muscle damage and hypertrophy stimulus—use sparingly with beginners.
Intensity Techniques (Intermediate+)
- Drop sets: reduce load after failure
- Rest-pause: brief rest within set
- Supersets: agonist-antagonist or pre-exhaust
- Cluster sets: intra-set micro-rests
Not for novices learning motor patterns.
Exercise Order Rules
- Neural-demanding first: Olympic lifts, jumps (fresh CNS)
- Compound multi-joint: squat, deadlift, bench, rows
- Accessory isolation: curls, extensions
- Core finisher if not primary fatigue concern
Alternate push/pull to manage fatigue: bench press paired with row.
Worked Scenario: Plateaued Bench Press
Client stalls at 185×5 for 3 weeks. Options: (a) add fourth weekly chest day with junk form, (b) deload 10% one week then progress, (c) jump to 205 immediately. Best: deload then micro-progression (+2.5 lb) or add back volume via rows; ensure sleep/protein.
RPE and RIR Scales
RPE 8 ≈ 2 reps in reserve. Autoregulates daily readiness better than fixed percentages for non-powerlifters.
Exam Traps
- Trap: 3-minute rest for hypertrophy cable flyes—unnecessary; 60–90 sec typical.
- Trap: Isolation before squat on leg day—fatigues stabilizers before heaviest pattern.
- Trap: Equating high rep light band work with strength stimulus for advanced lifter.
Special Population Notes
- Hypertension: avoid heavy Valsalva; use controlled breathing, moderate loads
- Osteoporosis: axial loading with proper form stimulates bone; avoid flexed spinal loading
- Adolescents: emphasize technique over max loads
Resistance variables translate goals into session plans—the operational core of ISSA CPT practice.
