Find a workout for either cardio(legs,running), upper body, lower
), or all, stick to it, or create your own workout
plan that's best for you. I work out, do pilates, and yoga 2 times a day, and im so happy for where i am.
So, just motivate yourself. Its all that. Tell yourself you can, then you will, then you can get the body you want!
Hope that helped!
