Do regular full body workouts/yoga/antagonist work. A lack of core strength and scapular stability will end up wrecking you if all you do is climb.
To get better at climbing, training helps a lot. But 90% of the training you need to do is just climbing more. Your problem isnt that you arent strong enough, it’s that you havent developed the necessary techniques to climb harder because you havent experienced enough rock. 90% of the change you need to improve your climbing is simply to start consistently logging what you do in your climbing sessions.
Work your way up to climbing 20 pitches per day, 4 days per week, lowering the grade as much as needed to get the pitches in. You’ll find your biggest problem here is simply time management and finding a willing partner. This is a great time to get used to leading, since almost all your pitches will be quite easy.
Once you can consistently get 20 pitches in per climbing day, start increasing the number of pitches at your onsight grade. Your sweet spot for progression is a climb that you may or may not be able to get on the onsight attempt, but which you will probably get second go. Aim to put 10 burns on onsight-level climbs per day.
Once you stop easily progressing through the grades week by week, your climbing logbook comes into its own. If you find that a certain grade feels like it would take more that 2 or so attempts to put down, start tracking sends in the grade below it. You are only allowed to be disappointed in your inability to send the new harder grade in when you have put down 100 sends on the grade below it.
When progress starts stagnating purely from increasing volume, start bouldering one or two days per week instead of rope climbing. It can be satisfying to send boulder problems, but spend at least some of your time on boulders that are so hard that you can only do one or two moves at a time - practicing doing just one or two extremely hard moves at a time is where you will really learn how to use your body. It is helpful to boulder in a big group, so you are forced to rest between burns.
The easiest way to improve at climbing is to climb a lot with people who are better than you. If you can do this, disregard all previous instructions and just go climbing with these people.

ok first of all what is a grade
