"I went from a 46 all the way down to a 32," Danny added.

Fitness experts say one key to success is having someone else to lean on.
"A workout partner is key. Accountability is everything," celebrity fitness trainer Latreal Mitchell told ABC News. "Not every day you're going to want to go out there and give it your all. At least you'll have someone to say, 'Come on. Today is my day to uplift you and vice versa.'"
Danny Reed now weighs 191 pounds and Lexi is down to 182, but they said this was no easy feat.
Additional tips from Mitchell include be honest with yourself and what you want to do, get rid of the excuses, hold yourself accountable for what you say you want and give yourself a realistic time to get it done.
