Great log man. You've got the endurance conditioning all sewn up. This article may help with your lifting, as you've mentioned, you're bored. I think a routine like this would fit nicely with your goals. No more single plate bench and squat ; )
Functional Power Training for Wrestlers
I'd exchange pull ups/chins for lat pull downs. Change up your rep/set schemes. For your main lifts try alternating 8x3 and 5X5 on a weekly weekly basis. Something about 5x5 bores me to death. You may respond better working up to heavy doubles or triples for squats and bench. I did. Keep up the good work.
