Sets & Reps by Goal
Strength
- Sets
- 3–4
- Reps
- 5–8

Isolation movements can be trained with moderate loads for strength, though peak strength expression is secondary to compound lifts.
Hypertrophy

- 3–5
- Reps
- 10–20
- Rest
- 45–90 s
Isolation exercises shine in the 10–20 rep range with a 2-second eccentric. Taking the final set close to failure drives maximum hypertrophic stimulus.
Endurance
