A practical starting dose
Five exercises times two sets gives ten working sets in a full-body session. For a new or returning lifter, even one set can be enough during the first week of learning.
Use the rep range as a guardrail
Choose a load that makes the target range challenging without grinding. If you exceed the top of the range with stable form twice, increase resistance slightly.
Add sets only for a reason
A third set can help when a muscle needs more work and recovery is good. Do not add sets because soreness has disappeared; adaptation often reduces soreness while training remains effective.
