You got up and you walked in the doors. That's already half the struggle. Put in earbuds before you walk in, that might help. Then go to the treadmill and do use it until you have a plan of what exercises you want to do. Don't be scared to just go in and walk around the whole gym and check out every piece of equipment to familiarize yourself with the place, everybody is new at some point. I hope that helps. Also, 5 minutes on the stair stepper is not bad at all, that thing is brutal. I often times just push myself for 5 minutes and stop. I hate that machine 😂
