Past workouts can not be moved forward if you've already done the workout.  

If you couldn't do a workout fully on the day for any reason, don't worry about it, just move forward.

Never "make up" missed workouts, and don't make up a workout that you felt wasn't good enough. Just move on to the next. We always say that we only look forward in a training plan, never backward.

All of the workouts in a week are built to work together, so if you're duplicating workouts by re-doing them, you're tipping your training balance in a way that isn't intended with the rest of the week.

Even if you cut a workout short, or adjusted it, they're still not meant to be repeated.

Remember: you aren't trying to "win" your training sessions. Do your best, and leave the rest.
