The Claim
In young, untrained men, combining multi-joint and single-joint exercises for the triceps (regardless of order) results in greater overall triceps hypertrophy than either exercise alone, but this is due to complementary stimulation of different muscle heads rather than additive effects.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you're a guy who's new to lifting and you do both big compound moves and isolated triceps exercises, your triceps will grow more than if you only do one type — not because the exercises add up, but because they hit different parts of the muscle in different ways.

What the research says
1 studyWhen young men did both bench presses and triceps extensions together, their triceps grew more than when they did just one type—but not because the exercises added up. Instead, each exercise worked a different part of the triceps muscle, so together they covered all parts better.
