What should you do when you miss a day of your routine? Don’t miss a second. Be nice to yourself, no negative self talk. Stuff happens, and it’s better to roll with and move on than to focus on the negative. The key to recovering from a missed day is to not miss a second day. Missing a second day is a pattern which is hard to stop. That’s why I only ever have one day gaps between my workout days. Any more and I’m much more likely to stop.
