When I feel like overeating, skipping a workout (for no reason), or just going thru the motions (just because), I remind myself those seemingly insignificant actions will have a significant compound negative effect on my fitness.
Can you relate??
It won't show up today, but the bad habits start to show up in how you feel, how you think, how you perform & then how you look. You can't give up fighting that negative voice in your head trying to distract & deter your discipline. Train your brain to shut it down & instead repeat all the ridiculously POSITIVE thoughts
