So this past week was very successful. I upped my carbs more and have had no problems with LP the whole week. I did bench press before deadlift on Wednesday with no problem. Bar went right up every time.
Deadlifts made my back so sore I didn't know if I'd be able to do squats Friday, and was contemplating going on a 1 on, 2 off thing and delay Friday's workout to Saturday, but my back recovered quickly enough that I decided to give it a shot, and am glad I did. Squats went up every time and were fine.
Next press will be 140.5 lbs and bench will be 200 lbs. Pretty proud of that given my size, structure (5'9" ectomorph who when young, was lucky to hit 145 lbs in high school), age and training experience.
My squats are behind because of all the resets and other issues and not proud of them, but I know they'll catch up now that I see the mistakes I made (calories, wasn't supposed to be doing resets at my age, anyway according to Barbell Prescription, have had a couple technique issues to work out).
I'll make sure calories are not the issue when I finally end LP on those, and have upped protein and fat a little more with the carbs.
So I don't know what was up with the pressing/deadlifting thing but whatever. I do know I had low energy and that wasn't rocket science to see why.
Thanks again for the help, anyway!
