You wake up feeling off. The sleep was bad. The week has been heavy. The session you have scheduled feels enormous. The list of reasons to skip is well-prepared and partially valid.
The temptation is to negotiate. I'll train tomorrow. I'll do something lighter at home. I'll take today off and double up later in the week. All of these are plausible. Most of them are how missed sessions become missed weeks.
Here is my default move on bad days. It has not failed me yet.
Go to the gym anyway. Do the lightest version of the planned session. Use the warm-up weights. Move through every exercise. Do half the prescribed sets. Be out the door in 25 minutes.
That's it. That's the whole framework.
The reason it works has nothing to do with motivation. It works because the threshold for showing up is the only threshold that matters. Once you are in the gym, the friction to continue is dramatically lower than the friction to start. Many bad days, once you've gotten moving, turn into normal days. The first 10 minutes were the issue. The rest unfolds.
The bad days that stay bad — and there are some — still get a small session done. The habit is preserved. The streak is preserved. The identity is preserved. You are still a person who trained that week. That matters more than the quality of any individual session.
What you do not get to do is skip and tell yourself you will make it up. The makeup session is a fiction. The fiction is cheap. The thing it replaces is real.
Show up. Train light. Leave. Repeat.
The bad day was always going to happen. The skill is having a default response that doesn't compound the bad day into a bad week.
