Training on consecutive days

If workouts have to be missed for whatever reason, is working out two days in a row a good way to go about getting back on schedule?  Or is this a bad idea?

You can do that. Just be aware of issues like optimal rest, nutrition, sleep etc.

Is it something from this week you are going to miss or from a previous week?

From a previous week, I'm 2 workouts behind schedule.  Did last week's wednesday workout on monday of this week.

You have some options then.

Dependent on how you feel you could skip one of the missing days and add the last one to this week workouts.

Missing one workout is not a catastrophe. Missing one work per week on a consecutive basis or missing workout frequently is a problem.

Training on consecutive days is fine if you have too. I and others I know have trained Mon/Tue/Thu/Fri without any issues. It's not ideal but it still works fine. As just a one of 2 days in a row definitely won't be an issue. 3 days in a row gets rough though... believe me.

Thanks guys.  Missing workouts is quite rare for me so this time I'll just do a couple extra workouts to catch up.
