[Daily Log] Day 3: The Sedentary Struggle's Counterattack? Moving During Algorithm Runtimes!

Hello everyone, it's your fellow grad student who eats out, reporting for Day 3! I received some really practical advice yesterday about pairing meals when eating out, and I'm definitely going to try it for my next meal! Today, I want to talk about another major nemesis – 'sitting for long periods.' Staring at the screen coding, reading literature, or waiting for algorithm results to process is basically my daily life. Sometimes when I get really focused, or when I take a break to de-stress with a few games due to pressure, I end up glued to my chair for hours. Every time I snap out of it, my shoulders and neck feel incredibly stiff, and my lower back aches subtly. So, today I set myself a small mission: whenever my program starts running, during any waiting periods, or during breaks between games, I force myself to stand up, get a glass of water, and do some simple stretches by my desk. Even just casually stretching my limbs or twisting my neck, I've surprisingly found my mind feels a bit clearer and less groggy! I'd like to ask everyone here: do you have any recommended mini-exercises or stretches that can be easily done by the desk, or even 'while sitting in a chair'? I'm particularly looking for moves that help relax the shoulders and neck, and alleviate lower back pain. I hope to learn a few more tricks from you all, so that even as a heavy sitter, I can 'recharge' my body anytime while I'm busy meeting deadlines!
