Hi and welcome to the forum. Great job on deciding to get healthy after the holidays. So how much are you wanting to lose. For someone who is 5'3" 136 isn't that bad...weight range is like 120-130 I think. I am 5'2" and I'm 191lbs. Maybe after you lose a few of those extra pounds you can start toning your body. That's what I want to do when I get down to that area of weight.
I wish you luck on losing the weight!
