Just remember, all it takes to start an exercise session is one foot ahead of the other. After that, you can't help but just keep going.
I absolutely hate mornings, but that's the only practical time for me to exercise. Getting out of bed is SO HARDDDDDDD. But once I start exercising, the only thing that stops me is the clock telling me to stop and get my butt to my office jobs.
Also, I've been exercising a minimum of 4 times a week for the past 8 months. Lost about 8 pounds, but my shape has changed a lot, for the better! Make strength and excellent posture your aim, and you will look 10 lbs lighter automatically.
PS: Practicing good posture hurts for about a week, then your upper back and schoulder muscles get used to it and get stronger, and there you are, looking red carpet ready. Try it.
