Nice to have you onboard Tracie
Lack of motivation can be hard!
First off what are your goals? If you haven't any sit down & think about it & then write down exactly what you want to achieve. Make sure your goals don't conflict is stage one. If you say something like "I want to lift a world record deadlift" & you also say "I want to slim down to a size 8" then there's the first problem. You're trying to do two opposite things, so writing down can first help clarify your exact goals in your head. Once your goals are clear you can put it up somewhere you see it often (even make a few copies - put it up as a 'sticky' on your computer where ever you will see it), this will remind you of your goal & help keep you on-track.
Next will depend on your what your goals. but most people will need to buy a training log. This doesn't have to be fancy just buy an exercise book or similar & plan out your training & diet. The details will depend upon your goals.
Here's a few examples:
Let's assume your goal is physique based, you want to get ripped for summer:
1/ Write the goal down & put it a few places (stick it to the fridge, sticky it on your computer)
2/ Set aside 2 or 3 days a week to train, set a time & day.
3/ If you have any 'problem foods' in the house that will affect your goals get rid of them, go out & buy healthy food options (you can still have the odd treat, but build that into the program).
4/ Once a week in the morning in bikini or underwear photograph yourself. Take a couple of snaps somewhere that you can do regularly, at the same time of day, in the same outfit. Also measure the waist size & you can weigh yourself (although weight can be the least affected when you lift, go by waist & photos when considering fat levels as you could be adding muscle).
5/ Begin training & starting shifting to a healthier diet.
Things to avoid are to make too many changes at once or you could get overwhelmed. If you have a specific deadline, then you have HAVE to do that, but if it's a lifestyle change you're after then I'd suggest getting the training started & just make one or 2 dietary changes (remove the real junk as much as you're comfortable doing). From there make no more than 2 changes a month & only once the last change has become habit.
