Life happens, you will miss workouts. Work emergencies, kid functions, getting sick, etc. These things are unavoidable and out of your control. Just pick up where you left off on the next day.
But for most weeks life is normal. Or at least normal for each invidual. My normal may be very different from your normal!
WHile I do not love ultra strict training programs because they can easily get derailed, which in turn frustrates the trainee to the point of quitting. I do plan out my week. I have an idea of how many days I will strength train, how many days I will do an intense Cardio or HIIT workout. Based on what my week looks like I plan on re-arranging these workouts to fit my week.
Plan
In general, it’s good to have a plan of attack. For a normal week it can simply be setting strength training on Monday, Wednesday and Friday. With cardio workouts Tuesday, Thursday and Saturday. Take into account the various known obstacles of Weather, Work and Guests and plan around these areas ahead of time.
Weather
Check the weather for the week. Will there be days you KNOW you will not be able to do any cardio outside? Make that a gym day instead. Or if you are typically a night runner, but that day calls for PM rain, take your run in the morning. If it looks like it will be a beautiful weekend try to plan for as much outside cardio as you can for that weekend. Plan around the weather. Be congnizant of it. Yes the weather reports can be incorrect, but when the weather calls for 3-4 straight days of rain, the reports are often more accurate. Plan around this.
Work Schedule
Do you have a day, or mutliple days with long meetings ahead? Days that can typically get away from you and your typical 5pm ending time will run much later? Plan to work around this problem. Set these particular days as a rest day. Or simply do the workout you had planned that day in the morning.
Guests
If you know you will be having guests arriving at your house, plan ahead for this. If your guests are coming for a Friday-Sunday, stack your workouts Monday-Thursday.
