what is the best workout to get tone and in shape?

hi all

I’m 5 4″ ,123 lb
I am average built and a little out of shape, my legs are fit and ok but my upper body is awful especially my arms and my AB, so I rally like to get in shape and tone my body before summer vacation
I’ve finished turbo jam beginner workout program it helped but not that much I wished. After finishing that I had to study for my exams and lots of other foolish excuses so I stop exercising for 3 weeks and now I have problem starting it, I’m super lazy!!

Apart from that I have difficulty deciding whether I should do advanced program (which is harder cardio workouts) or redo the beginner program but this time ad a little more ab workout everyday or I should change to Chalean extreme which is more weight training than cardio?
which do you suggest?

My measurements are

Chest 35.8 in

Right Upper arm 11.4 in

Waist 28 in

Abdomen 34.3 in

Hip 36.6 in

Right Thigh 21.3 in

thank you in advance for helping me get in shape :D
