DE Squat Day

Today was as the title says, dynamic squat day. We did 12×2@240lbs onto a box. By the end my right knee was nagging me again and so was my lower back. As I type this my knee is becoming inflamed, I think I need to do some icing over the next few days and maybe skip squats this weekend if it doesn’t get better. I believe I injured it trying to do a wider stance for squats which apparently my body doesn’t like so it’s back to my normal stance.
So this might be the end of shooting for my 405 squat goal by year end, I’d rather miss this goal and not permanently injure my knee.
