Wasted session

Went  to do some accessory  stuff...big mistake on my part.My shoulders were pretty much fried from all the squatting I did yesterday. Worked to only 180lbs on Military press for what should have been a easy set.After which I just shut it down felt like hell warmed over. In all reality I am going to go to the three day option present in Lilly's E book and just tweak some of the accessory stuff. The harsh reality is at my age and not " supplementing" It pretty hard for me to recover from four days a week.
