Quoted message said:I have read conflicting information about sore muscles. Some say you
should only have sore muscles as a beginner ...
Only partially true.
Quoted message said:... others say substantial
muscle growth can only be achieved when you experience sore muscles.

Quoted message said:I am a beginner and am primarily interested in gaining strength - not
neccessarily size (if it is valid to make that distinction).
Only partially valid. There needs to be some muscle fiber growth to
increase capacity for strength, but a large part of strength gain is
neuromuscular adaptation. That comes with practicing the particular
movement.
DOMS (Delayed Onset Muscle Soreness) is *not* necessary, or even
optimal, for strength gain. Beginners will get DOMS pretty regularly.
Experienced lifters will get DOMS sometimes, often after a lay-off, or
when performing a movement which they haven't done in a while, or when
changing exercise intensity.
It's not a bad thing, except that it may extend recovery time, but
it's not necessary for muscle growth.

Lift weights?
