I’m in my 20th year teaching elementary special education(learning support). I train in the morning. Wake up at 4:55 every morning during the school week. I’m on the trainer or at the gym by 6 am. Luckily I live and have a gym that is less than 10 minutes from where I work. I stop working out at about 7:45 and shower and get dressed. I get to school by my contracted start time at 8:10. I’ve been doing this routine for way to long but it works for me.
My wife is also a teacher with an earlier start time than me so I would have to get up this early no matter what.
I find getting my workout in before school helps me during the day. I have no pressures when I get home and find that working out helps clear my mind for the day and makes me a more relaxed person. It also helped when we had kids at home. I was able to support them and their activities which were always after school and evenings.
I’ve learned to leave work at school over the years which is a huge help.
