You don’t stop brushing your teeth for the rest of the week simply because you fell asleep before brushing them on Tuesday night. You wake up the next morning, brush your teeth, and continue with your life. Training is the same. Just go train.
Problem #2
The more insidious problem is that, by deciding not to train for the rest of the week, whether it’s Wednesday, Thursday, Friday, etc., you have now decided to practice skipping workouts.
You have now decided to make skipping workouts your new habit.
You’re practicing the very habit you’re trying to avoid - that of missing training sessions.
