We often get in a mindset that if we can’t do it perfectly, then why do it at all? Nothing could be further from the truth. Pretty much doing ANYTHING is better than nothing when it comes to getting more fit, losing fat, getting stronger, etc.
Let’s use the example of my lunch time walk with my wife and dog today. Using a Garmin vivofit (basically a fancy pedometer), at the start of my walk I had 3,258 steps for the day and burned 1179 calories (resting metabolic rate + activities for the day so far). At the end of the 35 minute walk, I had a total of 6,421 steps and 1,347 calories. So that walk added 3,163 steps and 168 calories to my day.
If all I did was walk 35 minutes a day at a leisurely pace, I would lose a pound every 20 days. That would be 18.25 lbs a year! That’s no small number. Now those numbers would be different for you unless you’re a 210 lb dude, but I think you get the picture.
The moral of the story is tell the perfectionist in your head to be quiet and just do something.
