go to a gym, you'll need to do freeweights
barbell or dumbell, doesn't matter, although you have to use barbell on squats and deadlifts
squats and deadlifts for lower body
bench press, overhead press, and pull-ups/chin-ups for upper body
those are the CORE compound lifts, don't even think of doing the small accessory lifts until you got the basics lifts down
look up youtube video for proper form tutorials because they are dangerous if you mess them up
as for a basic workout plan, do push/pull/legs, very beginner friendly
push things on push day: bench press, overhead press, triceps
pull things on pull day: pull-ups/chin-ups, other lat exercises, biceps
leg day: squats and deadlifts, along with small stuff like calf raises, also ALWAYS do squats before deadlifts, if you do deadlifts before squats, you will be unable to squat as your back will be too tired
you can do PPL 3 times a week or 6 times a week
if you do it 6 times a week go heavy on one day and light on the other
