For people looking to get started, I would suggest Starting Strength, which is a book on Amazon (pretty lengthy, but extremely thorough) or Strong Lifts 5x5 (google it to find the program it’s free on the web).
The basic gist is to do full body barbell movements for 5 sets of 3 or 5 and increase the weight by 5 pounds (2.5 pound plates on each side of the barbell) per session.
The basic barbell movements are
Squat
Deadlift
Overhead press
Bench
Bent over row
(I don’t do power cleans)
Do YouTube proper form, benching especially can rip up your shoulder when done incorrectly.YouTube channels I watch to keep motivated and to learn stuff like form and nutrition (they limit the bro science as far as my untrained eye can tell):
Alan Thrall
Jujimufu
Eric Buggenhaggen
Jeff Nippard
Scooby1961

Remember the following:-no one is looking at at the gym
-lift only what you can lift, start slow, you will progress very quickly
-Commit to going every week three days a week, except for illness and injury
-Carefully watch form videos on YouTube for the lifts (Alan Thrall and The Art of Manliness are the best)
-If you do sustain an injury, let it heal for a weak or two, but continue lifting around the injury
-strength training is not body building, but it is the ideal place for creating a foundation of strength and overall health, you will lose weight, you will gain muscle and you will be out of the gym in under an hour with the basic barbell movements.
I’ve been lifting for 7 months now and I love it. I suggest everyone do it.
