Listen to Runningart. He's been around LRC a long time & his knowledge of lifting is second-to-none here. End of conversation.
Concur. Runningart2004 has been there and (especially) *done that*. He's our primary source for sound lifting advice (and thank goodness he won the Runningart challenge and didn't have to leave LRC!).
A few wrinkles:
If you can get someone knowledgeable (maybe a brief trial membership in the gym?) to check your form, do it. YouTube videos are tremendously helpful in imparting correct form, but on some movements it can be hard to know whether in fact you're using the form they recommend.
When you're learning any skill, do it when you're fresh (though after an appropriate warmup). Don't try to acquire lifting skills after a full running session.
And don't try to do two things at once: In the first couple sessions, when you're learning, don't try to lift a lot of weight; focus on the form and use weights just heavy enough to give you the feel for the exercise.
But once you *have* learned an exercise, don't stay with relatively light weights. Move up and *keep* moving up, as long as you can maintain sound form. Once you have sound technique, never be afraid to fail on a lift--failure means growth! But fail "in line"--don't start twisting your body around to horse the weight up any old how; always maintain good form.
When learning lifting exercises, even with relatively light weights, you're likely to get sore--even with good instruction and good form. This is so-called learning or coordination soreness that comes from tensing muscles unnecessarily (so you end up pitting the working muscle against its atagonist, which should be relaxed). It may show up a day or two after your session. It will pass; sleep, hydration, and good nutrition may speed its passing a bit.
Different things work for different people, but this has worked for me:
For one week, one set per exercise. Then
for two weeks, two sets per exercise. Then
for three weeks, three sets per exercise. Then
go with however many sets are approriate for a given movement.
