Rob you've confused me with all the stuff you're doing. Were it me, I'd just go back to basics of primal type fitness and follow a more simplified regime for a while. I am trying to keep it simple and low key myself. I started off in March with just doing HIT rowing twice or three times a week. In June I added Body by Science strength training once a week. Now that I have lost over 50lbs I am moving on to bodyweight exercises with some weight and sandbag (just bought one and the inners still need filling) thrown in. I am unable as yet, to do proper press ups but I'm getting there and do good form ones on the side of the bath. I use two chairs to do dips with my feet resting on the floor. I sold the rowing machine and bought a pull ups/dips/leg raise tower and have started using a chair so that I can get my legs to assist the pulls up and chin ups at the moment. I've got an old 70ltr rucksack containing some camping gear, a bag of sand & two 10kg weights for extra weight when doing squats. I just do what I can do, although I come away with jelly legs and spaghetti arms.
Bottom line, it sounds to me as though you're doing too much at present if you are not improving your performance. Of course, I am no expert as I've only my own experience to go on. Also, I was told by a gym teacher when I had an off day doing the BBS "Sometimes you're just not up for it, forget it and move on."
Why use a sledge hammer to crack a nut when a steam roller is even more effective, and, is fun to drive.
