Speaking of the public workout, it's all happening now! Some of the losers do it outside, others are in high school gyms. And there are special guests! Season 11 winner Olivia is on hand to help Danni, and she still looks fabulous. Joe works with a crowd that includes a whole bunch of kids. Jackson runs around with his crew, while Gina makes her challengees do push-ups. Danni is thrilled that her dad is in the crowd and breaking a bit of a sweat. Gina has a family friend named Matt who is over 430 pounds and she's able to practice her future career as a motivational speaker with him. Season 11 contestant Marci is there, too, to offer extra encouragement. Gina reminds us that you don't have to be the fastest -- you just have to keep moving, and we get a montage of people slapping hands and having triumphs of the spirit and stuff. And then they get Subway gift cards. Maybe a yogurt, too?

We then catch up with Sunny, who talks with some of her friends about how being overweight has affected her life. Her friends are happy to see her so radiant and full of self-confidence, and finally realizing how beautiful she is. Sunny admits to hating herself at various points in times and doing things that were self-destructive. At one point, she even tried purging, but was thankfully unsuccessful. The fact that she never talked about it hurt her even worse, and Sunny and her friends talk about how it's a difficult, but possibly necessary subject to broach. They're a nice supportive little group and Sunny appreciates them. Group hug!

Biingo, meanwhile, talks to her sister Faith, who is 19. This is apparently in itself an unusual occurrence. She tells him that it's inspiring to her to see him with so much confidence. She's proud and loves him, even though she doesn't tell him all that often. Biingo appreciates it and loves her too. Faith eloquently states that you can always change your lifestyle, and it's inspiring to see someone younger than you do something that you didn't even have the courage to do. Biingo hopes that they can have more heart to hearts in the future, and I think he's glad to be in something other than the role of the annoying little bro.

And then Jackson works with the kids at the non-profit organization where he volunteers, teaching a class about goal-setting. His goal, of course, is to lose five percent of his body weight while still doing all the volunteering that he loves so much. Cut to Gina, who sort of rambles around aimlessly at Planet Fitness. She knows she has to learn to be her own trainer and motivator, but is uncomfortable with it. Jeff jogs outside and lays out his exercise mat in his bedroom. Danni works her two jobs, and says that finding the time to get her workouts in is going to be a real struggle. Joe and his brother, Henry, challenge each other and trade tips and tricks. With 24 hours until the weigh-in, Danni takes a jog, Joe and Jackson hit the elliptical, Gina lifts weights and Jeff uses his in-room equipment. They're all going for the five percent target knowing that if they don't hit it, they have a good chance of continuing their stay at home permanently.
