Had my fasted workout interrupted by some crazy thigh pain. Wasn't sure if I pulled something or if it was just awakening DOMS from those SSB squats, but I stopped at rep 13 of burpees out of concern. At this point I had done 8 minutes of the exercise bike and burpees. Took a break here to walk around and do some chores like water my plants, assessing my leg. Went back to about 5 more combined minutes of the exercise bike and light shadow kickboxing. It just feels like really bad soreness but some injuries start off that way except the soreness never goes away, so I'll be taking it easy on my legs today. Planning on hitting the heavy bag later.
