New climber

Recently got into bouldering for the first time and it is probably the most fun I have had doing anything in a while and would love to get into it so was looking for advice on how to make as much progress as I can without risking injury and while also considering the fact that I already go to the gym 6 times a week (PushPullLegs). My finger strength seems to be holding back a lot with all of the routes that are challenging having tiny/thin holds that I can comfortably hold onto but find difficult to move on to the next hold without slipping so any tips on that would be great but tips on literally everything else would be great aswell.
