tweaked my knee on the leg press on sunday morning. Was feeling good and strong, was using the flex leg press which i like a lot was going nice and deep, but not too deep, I like to stop when my back just starts to roll up, cause have hurt my back on the LP before. so was getting below parallel though. good warm up 1 plate per side up each set, may have jumped up 2 at 4 or 5 plates or so. 8 plates PS felt super light pumped out 12 easy held back some cause i was thinking about hitting 11 PS which on that machine with a full ROM is HEAVY for me (205 Lbs) well i start the set with 9 plates PS and it was going nice and smooth then about rep 3 my knee starts to feel hot and a twinge of pain sets in. I racked it and that was it for LP, did some light extensions with no real pain.
Have hurt it before much worse, just some tightness today. was bummed though cause I love to train legs hard and it kills me to back off. But as a guy who i used to train with said, "live to train another day" One of the best things i learned with him is if you injure yourself in the gym stop doing that exercise and back off, you will heal up quicker and not do any further damage.
