What do you think?

I am currently in the process of losing weight. I have lost 20 pounds and have about 25 more to go to get to my goal. I also want to tone my body up such as my legs, thighs, and butt. I am unsure if I should focus on losing the weight first and then focus on toning or if I should try both at the same time. What do you think would be easier to accomplish?
