This is the typical “All or Nothing” mentality: either I do everything perfect, as I had imagined it would be, or I give up. Things rarely turn out as we have dreamed, and hoping so is an unrealistic strategy.
If you’re thinking of quitting because things aren’t going the way you planned, don’t quit. Readjust your plan.
You had planned to exercise 5 or 6 days a week and now it is becoming very difficult for you. Don’t give up. Take a couple of days off while you plan your next workouts, but this time only 3 days a week. This is often enough for any beginner to see changes in 4-6 weeks.
On this journey, you will find more than one obstacle. This year you may have a sprained ankle, you may have to put in extra hours to finish a project at work, or you may have to spend more hours than you thought studying for an exam. Life is full of unforeseen events and obstacles. What will you do then? Stop training because your circumstances aren’t perfect? Accept that you have to adapt your training to your circumstances and that rarely there will be nothing that will not interfere with your plan to get in shape.
It’s not about doing it perfectly, but about doing it better than you’ve been doing it. If you didn’t exercise at all last year, training 3 times a week this year is a giant step forward.
