I do flexes and crunches to strengthen the abdomen, which helps a lot in maintaining proper posture. I also get on the treadmill every day. I love the results but I get bored with the repetition. So to make the time go by, I use it to go through my challenges of the day, how I should deal with them and how I should plan my day. I get on the treadmill asking how in the hell am I going to get a client to say “Yeah, you’re asking a lot of money but we want to do it.” How do I frame a lecture I’m going give this afternoon to best motivate my students to learn the lessons? How do I deal with this family problem that I’ve got?
