I always add more on if I'm able to complete the set. How much depends on how hard the last set was for me.

For example, lifts that work small muscles, like the military overhead press or power cleans, might only go up by 1 lb/session, as a +5 lb progression might cause premature failed lifts. (You need to buy micro plates if you are serious about strength training; gyms won't have anything lower than 2.5lbs and if they do, they don't have many of them.)

Re: programming. anyone can make progress on 3x10 at first. The problem is that recovery will outrun your program as your training gets more advanced, which will eventually stall your progress early. See this article that talks about this: https://startingstrength.com/training/3-sets-of-5.

Now, 3x10 or more can be good for hypertrophy if you're using light weights. I use 3x12s in my program for big assistance lifts, like dips and pull/chin-ups, but you can't get big without getting strong, so why not do it right the first time? Elite physique bodybuilders can usually move insane weight for this reason.
