It’s very normal to be mildly, moderately, or very sore with limited mobility after a workout like we did on Friday. That means you pushed yourself beyond what you have before, and are establishing new comfort levels. However, if you experience any symptoms of rhabdymyolysis (severe pain, dark coca-cola colored urine), please seek medical attention immediately! This is no joke and can be treated if caught early. It can be very dangerous if not deadly if not treated.
