Have you ever had one of those workouts where you had the entire thing planned and then, while doing the workout, you wanted to go home and just end the entire workout? I'm sure you have if you've been training for any length of time. The key to those situations is in how you deal with them as they come up.
Baby Steps
I tell my clients to handle these issues using baby steps. Instead of trying to “get through the workout” just get through the next set. Other than each repetition, a set is the smallest unit of measurement when training. Use that as a baby step towards completing your workout. You will quickly see the value in handling things that way. As you complete one set you will be ready to complete another and then another and so on until the entire workout is completed. Use baby steps to your advantage.
Music
If you are having one of those days change up the music you are listening to. That will change your mental state and help you get through the workout. Combined with baby steps, I guarantee you will be able to finish any workout you start. Music is huge because it calibrates your mental attitude during the workout. Maybe you just aren't feeling the music today and that is translating into you not wanting to train? Fix it!
Daily vs. Weekly Goals
Many people who set goals set them for too long of a time period. Like anything else, we need to be able to see some tangible results or we will be ready to give up. This is why it is essential to set manageable goals. If you set your goals for too long of a period you are going to give up for sure. I like to have daily, weekly and monthly goals. By setting daily goals you will be able to use those goals to get yourself through the workout that you are ready to quit on. Just recall the goal and push through to the end.
Sense of Accomplishment
By pushing through and using the techniques above, you will have an incredible sense of accomplishment. You will gain momentum as you push ahead through the workout, a momentum that will carry you through to another set of workouts.
