Replying to Don't really feel like I'm progressing climbing

Really I only go to the bouldering gym about 4 times a week and climb outside a few times a month. But I'm still stuck on the same difficulty of problems after a few months of trying them. What happens is I get to a point I can get some of the easier V3s and V4s, but still can't get the harder ones even when they leave them up for a few weeks.

I think I need to work on technique cause a lot of the time I feel like I'm just muscling through it. Are there good videos/ training things I should check out?

Just looking for some help.
