I always try to get a meal in before my workout. Usually about 45-60mins before my workout so it has time to settle so I dont' feel so bloated while I work out. I think it must have just been fatigue because 220 3x5 on squats is a PR for me at the moment. I could try doing deads first but then I feel squats would suffer.... I guess you gotta pick one? Or seperate them.
