# Tension is the primary factor driving muscle hypertrophy
^1c0bda
## 1. Tension is king
- Tension is the force our muscles experience when they stretch and contract under load
- **Universally recognized as the** ==**primary factor driving muscle growth**==
## 2. Use bodybuilding technique
- **Lifting tempo: 2-4s negative**
- Eccentric phase is probably more effective than concentric for muscle growth
- ==**Pair slower eccentric with faster concentric movements**==
- **Proper ROM**
- LLPs / full ROM (see [[@jeffnippardWorldSmartestIntensity2023#^e9ce5d|Long-length partials lead to higher muscle growth than full ROM]])
- **Minimal momentum**
## 3. Effort
- ==**Push hard**==
- **Positive corrrelation between ==proximity to failure and muscle growth==**
- For 3 sets:
- Set #1: **stop 1 rep shy of failure**
- Set #2: **stop 1 rep shy of failure**
- Set #3: **all the way to failure**
## 4. Give your muscles a reason to grow
- **Apply** ==**progressive overload**==
- Option #1: **add reps with the same weight**
- Option #2: **add weight at fixed rep count**
- Option #3: **improve some aspect of your technique**
- Control the negative better
- Use less momentum on the positive
- Improve ROM
- Option #4: **improve mind-muscle connection**
- Can increase hypertrophy in some cases
## 5. Choose high-tension exercises
- Free-weight compound exercises like bench press and deadlift do not have the best "stimulus-to-fatigue ratio"
- Stimulus: how much tension the exercise delivers to the target muscle
- Fatigue: how hard the exercise is to recover from
- Deadlift: high stimulus and high fatigue
- **Machine and cable-based exercises generally have ==higher stimulus-to-fatigue ratios==**
- **Research shows they are ==as effective for hypertrophy== as free weights, if not better**
## Miscellaneous
- Rest for more than 1 min. between sets if possible
- Look at specialized hypertrophy techniques:
- LLPs
- Myo-reps
- Dropsets
- Forced reps
- Cluster sets
- Iso-holds
