Sherita Jackson
Giving up foods I love is tough, but I do have more energy. I'm adjusting, and it feels great!

Trainer Jeff Shablin says: Again, Sherita is on a winning track. She is improving in every area. I'm delighted over her progress.

Mary Leonard
I'm 100 percent positive that if this challenge was over tomorrow, I would not go back to my old eating habits. I feel too good! I really needed this challenge to get me started, and now I'm off and running. I've lost 12 pounds, but it feels like more.

Trainer Gabriel Gaskin says: I'm so proud of Mary and the progress she is making. Her clothes are swimming on her now, and she is just tickled pink!

Vaughn Morrison
Last week, I only made it to the gym when I met with Melissa. Unexpected conflicts keep challenging my schedule, yet I proposed to expand my Flab to Fab routine. I have been reluctant to weigh myself, but when I do I feel the scale is joking. It's saying I've lost over 20 pounds! Something must be wrong - right?

Trainer Melissa Kolczynski says: After three weeks of smooth sailing, Vaughn admitted to me that, for the first time, he's seeing that sometimes life gets in the way of the workout. He's doing a good job at making the workout a priority, despite how difficult it can sometimes be.

Cynthia Santiago
I was comparing the photos I initially sent, and I cannot believe the transformation that is taking place. I can see my muscular physique coming through. I'm sure I will surpass my 24-pound weight-loss goal. I'm looking at a size 8 - soon!!

Trainer Kimberly Garrison says: Cynthia is soaring. She has surrendered to the fitness lifestyle and is reaping the benefits. She realizes now that exercise and healthy eating work together like a marriage. Together, you're unstoppable!

B.J. Wilson
It's hard to resist eating things that you like. Clearly, the eating and mental challenges are the toughest part.

Trainer Jim Hart says: BJ is still missing those cheesesteaks. He is gradually adjusting to the inconvenience of having to pack lunch and not just run out and buy food. Despite having a cold, he continues to be faithful to the cardio program and loves his new heart-rate monitor. We also use it during strength-training to assess intensity.

This week he began interval training on the EFX and treadmill, which have jacked up his metabolism. He is becoming a lean, fat-burning machine! He has lost 13 pounds!
