Key Takeaways
- Volume = Sets x Reps x Load; manipulating these variables drives specific adaptations.
- Rest periods: 30 seconds-1 minute for endurance, 2-3 minutes for hypertrophy, 3-5 minutes for strength/power.
- Exercise order: large muscle groups before small, multi-joint before single-joint, power before strength before hypertrophy.
- Training frequency depends on intensity—heavier loads require more recovery (48-72 hours between same muscle groups).
- Intensity is expressed as percentage of 1RM; higher intensities (>85%) require fewer reps and more rest.
Training Variables
Quick Answer: The key training variables are intensity (load), volume (sets x reps x load), rest periods, frequency, and exercise order. Each variable must be manipulated according to training goals—strength requires high intensity with low reps and long rest, while hypertrophy uses moderate intensity with higher volume and shorter rest.
Volume
Volume represents the total amount of work performed. It can be calculated as:
Volume = Sets x Reps x Load
| Training Goal | Sets per Exercise | Reps per Set | Total Volume per Exercise |
|---|---|---|---|
| Strength | 2-6 | 1-6 | Low-moderate |
| Power | 3-6 | 1-6 | Low-moderate |
| Hypertrophy | 3-6 | 6-12 | High |
| Muscular Endurance | 2-3 | 12-25+ | High reps, low load |
Volume Recommendations by Training Status
| Training Status | Sets per Muscle Group/Week |
|---|---|
| Beginner | 10-12 sets |
| Intermediate | 12-16 sets |
| Advanced | 16-20+ sets |
Intensity (Load)
Intensity is expressed as a percentage of 1RM (one-repetition maximum).
| Training Goal | % 1RM | Rep Range |
|---|---|---|
| Strength | 85-100% | 1-6 |
| Power (single-effort) | 80-90% | 1-2 |
| Power (multiple-effort) | 75-85% | 3-5 |
| Hypertrophy | 67-85% | 6-12 |
| Muscular Endurance | ≤67% | 12-25+ |
1RM Estimation Table
| Reps Completed | Approximate % 1RM |
|---|---|
| 1 | 100% |
| 2 | 95% |
| 3 | 93% |
| 4 | 90% |
| 5 | 87% |
| 6 | 85% |
| 8 | 80% |
| 10 | 75% |
| 12 | 70% |
| 15 | 65% |
Rest Periods
Rest periods between sets depend on training goal and intensity.
| Training Goal | Rest Period | Rationale |
|---|---|---|
| Power | 2-5 minutes | Full ATP-PC recovery, maintain velocity |
| Strength | 2-5 minutes | Full phosphagen recovery, maintain quality |
| Hypertrophy | 30-90 seconds | Metabolic stress, GH response |
| Muscular Endurance | 30 seconds or less | Fatigue resistance adaptation |
Rest Period Guidelines by % 1RM
| Load (% 1RM) | Recommended Rest |
|---|---|
| 50-70% | 1-2 minutes |
| 70-80% | 2-3 minutes |
| 80-90% | 3-4 minutes |
| 90-100% | 3-5+ minutes |
Training Frequency
Frequency refers to the number of training sessions per week, either total or per muscle group.
| Training Goal | Sessions/Week | Rest Between Same Muscle |
|---|---|---|
| Strength/Power | 2-4 per muscle | 48-72 hours |
| Hypertrophy | 2-3 per muscle | 48-72 hours |
| Endurance | 3-5 total | 24-48 hours |
Frequency by Training Status
| Status | Recommended Frequency |
|---|---|
| Beginner | 2-3 days/week (full body) |
| Intermediate | 3-4 days/week (split routine) |
| Advanced | 4-6 days/week (body part split) |
Exercise Order
Proper exercise order maximizes performance and safety.
General Ordering Guidelines
| Priority | Exercise Type | Rationale |
|---|---|---|
| 1st | Power exercises | Require freshness for speed/technique |
| 2nd | Core/multi-joint strength | Most demanding, largest muscle groups |
| 3rd | Accessory/single-joint | Assistance exercises, smaller muscles |
Specific Exercise Order Rules
- Power before strength - Olympic lifts before squats/deadlifts
- Multi-joint before single-joint - Bench press before triceps extensions
- Large muscle groups before small - Legs before calves
- Higher intensity before lower - Heavy sets before lighter volume
- Compound before isolation - Rows before bicep curls
Example Exercise Order (Upper Body Day)
| Order | Exercise | Type |
|---|---|---|
| 1 | Power Clean | Power |
| 2 | Bench Press | Multi-joint strength |
| 3 | Barbell Row | Multi-joint strength |
| 4 | Overhead Press | Multi-joint strength |
| 5 | Triceps Pushdown | Single-joint |
| 6 | Biceps Curl | Single-joint |
Alternating vs. Superset Training
| Method | Description | Best For |
|---|---|---|
| Alternating | Alternate agonist/antagonist | Strength, reduces fatigue |
| Compound Sets | Same muscle, consecutive | Hypertrophy, metabolic stress |
| Supersets | Different muscles, no rest | Time efficiency, conditioning |

| Variable | Strength | Power | Hypertrophy | Endurance |
|---|---|---|---|---|
| Load (% 1RM) | 85-100% | 75-90% | 67-85% | ≤67% |
| Reps | 1-6 | 1-6 | 6-12 | 12-25+ |
| Sets | 2-6 | 3-6 | 3-6 | 2-3 |
| Rest | 2-5 min | 2-5 min | 30-90 sec | ≤30 sec |
| Frequency/Week | 2-4 | 2-4 | 2-3 | 3-5 |
