Hello! Does anyone have any recommendations for mid-day/work-day "wake me up" exercises or routines? I teach at a high school and I have a rotating schedule, which means at different times every day I have 65 minutes alone in my classroom. Sitting in a quiet room in a comfortable chair after teaching 2-3 classes (loudly and with gusto) can really mess with your energy levels. Sometimes I have to go from being louder than and managing twenty teenagers to reading or grading papers in silence. I get very drowsy/tired at these times, so I'm looking for exercies to wake me up, but that I can do in dress pants and a tie, in my classroom. (I do a lot of walking, so that doesn't do much for me). I'm also currently doing S&S and I just started working with the 32, so I'm looking for an exercise that could complement that. I used to GTG with push ups and pull ups, but being just over 100kg bodyweight and working with the 32, it was just too much, so I stopped the push ups and pull ups. I was thinking the hardstyle plank, but I'm open to suggestions. Thanks in advance!
