Uh-oh, tough love time!
OK, you said it yourself - you ARE "lazy". How can WE (how can ANYBODY!) HELP you?
We can cheer you on, give you suggestions, pats on the back, etc. But ONLY YOU CAN DO THE WORK. And I won't lie or sugarcoat it - the work ain't easy! - but if YOU want the REWARD, then YOU have to DO THE WORK.
This is true of everything in life. You want the paycheck? YOU gotta do the job. You want the grade? YOU gotta do the studying. And isn't that the way it is in life, in general? Should things always be "easy" for a person? What does "easy" teach us? Look what being "lazy" gets you. NOTHING. It doesn't make you feel good. It certainly doesn't do your body any favors. Muscles atrophy, fat accumulates, bones and joints suffer, nope! - just no good all the way around!
You don't have to get out & run a marathon. You don't have to "drop 20 pounds right now!" - You don't have to make huge sweeping strides in order to get off your *** and do something GOOD for your body. So that in return, your body can do something good FOR YOU.
Nike says it best... JUST DO IT. I promise, the more you do it, the easier it is to continue doing it. Baby steps! - those are fine! - Go for a walk for FIVE minutes. You can do anything for 5 minutes. You might find that once you're out there, 5 easily turns in to 10, or 15 or even 20. And before you know it, you're really digging it.
But DO IT FOR YOURSELF.
Believe that you are worth it!
