What A Load Of Bull Crap...

So I just came back from a lower body workout, I am SO disappointed on my performance... I couldn't even do 185 lb on my power cleans... May be I got 1 but thats all... I only got 175 x 3 today. I used to do 185 three reps before I slacked off because of Robotics. My bench went down, my squats probably got affected a lot too. I just feel terrible overall. I got 185 x 3 on bench yesterday, but last week, I got 185 x5... WTF...
