The correct advice there is that you should do deadlifts and/or variations, but also for every weighted exercise, you should take the weight seriously and learn proper technique. Don't ego lift and let your form deteriorate. Done correctly it should be perfectly safe. Personally I've found overhead pressing to be prone to to pulling my back, and only do it with a belt now.
