Dammit, had to stop my workout today after my first set of squats. No idea what I injured. I warmed up to 190lbs, got the first 4 reps in fine, they were definitely heavy, but I think I was still in good form, then when I started to push back up on the 5th rep, I felt an odd pop just under my left ribcage about inline with my nipple. I don't know what the hell it could have been or how I did something there, but I did something for sure. It's not an excruciating pain, but when I squat down even without the bar I feel tension there and any stretching of the area feels odd. Thinking I better just let it alone over the weekend and see how it feels Monday. Totally bummed, but just hoping it's nothing major.:(
