So I have been doing BJJ and Judo for around 5 years, and I have decided I want to start building some muscle to go with my technique since I am on the smaller side at 5'7 150. I train 3-4 days a week of BJJ/Judo, and I have been adding Pullups, Dips, Pushups, and Squats on my off days. I try to do these exercises twice a week.

My issue I am running in to is that I just don't ever feel strong, like my muscles are already cooked. I'm getting good sleep and protein is alright about 100-120grams. If on the off chance my muscles feel fresh, then I can do 3 sets of 10 pullups, but if I dont feel fresh, it feels like a struggle to get 2 reps. Any help and advice is welcome. I've always been active, but I dont know much about building muscle.
