Switch to Keto.
Watch the fat fly off and the gains pour in.
Isometrics are also wildly underrated and almost totally ignored by most so props for that because they generate exponential increases in strength as well as helping tendons/mind muscle connection by highlighting weaknesses in the chain due to compounding.
Also based on where you're at now I'd advise
stripping back your training to the absolute minimum for a while to allow the body a chance to rest and reset because you're on the verge of doing too much. Use that time to develop flexibility with yoga which once again builds the mind muscle connection and a totally different kind of power if you start holding extended poses. Then as you bring it back
focus on time under tension with very controlled, very precise reps. It's all about this:
People often skip the balance and think more training = more betterer when its actually about layers.
Build and release to create a new equilibrium then up the ante again.
Doing that brings in a second wave of "newbie gains". Rinse and repeat for the rest of your life and you'll never plateau, always grow and most important of all:
Increased functional strength which equals a far higher quality of living. Its all interconnected.
