. You and I are about the same size and we've lost about the same amount of weight! Woohoo! I'm also a loose 16/snug 14.
You can't really spot reduce areas but it sounds like you want to hit a number of areas, back, tummy, hips. Do you strength train? If not I would look into an overall strength training routine with dumbells. I do all my working out at a gym so my advice is based on that. Lunges are great for the butt and legs, I love lunges and they are easy to do anywhere as long as you have space. I use a bench that you can set at an angle and do sit up type exercises on it with a 2lb ball which is good for my tummy, another wicked good move for my tummy is lying on the bench with a slight angle, then raising my legs into the air, then tucking them into my chest. Omgosh, that's all I can say about that one! For my back I do assisted pull ups (these make me feel like GI Jane teehee!) My routine is a circuit based routine and I use probably 50% dumbells, 50% body weight for resistance.
You could look into an exercise ball too.
Just my 2cp!
