Every little counts, especially if you make it a routine part of your day.
Even on days that I can't get a workout in, I'll throw a few pull-ups in on my bar just for good measure. Sometimes I'll do half a workout. Sometimes I'll just do a quick set before I leave the house.
Every little bit helps. No excuses not to move your body for a minute per day. You'd be surprised how far it goes.
I did this and because it was so casual I didn't do proper stretching before or after and popped a tendon in my neck that laid me out for over a year. Be careful people.
