I try to workout as soon as I wake up so I can get it out of the way! If I don't get a chance to workout in the morning, then I make myself do it when I get home and before I eat dinner. You could also try making yourself a little calendar and mark off days when you work out...it can help keep you accountable.

Being fat is hard. Losing weight is hard. Maintaining your weight is hard. Pick your hard.
