I need to start getting fitter again, not fat reduction.

I have dumbbells, barbells, kettlebells etc.. at home, going up to about 80kg. So I'd like to do most of my workouts at home, then maybe sign up for gym membership later on.

Without a structured plan/routine I know I would stop, so for me I have to start and continue the plan, then get gym membership after.

I haven't a clue where to start in creating a workout routine so if anyone can help out with that it'd be cool. Or if there's a site I can go on that helps you create workout plans, that anyone knows of.
