Workout partner

Please help me work out and get back to where I want to be. I am a plus size model and I have a huge show in October so I need to look the part. Ps. Not all plus size model are full figured but thick and in shape for your clothes to fit you well and look appealing. I have been a plus size model for the past 9 years and loving it. I love the skin I’m in but I let myself go s bit. The first pic is a pic of me now the rest are like 3 years ago
