Individualized training for each individual client.
"Anyone can tell you do three sets of ten, but what it is, is getting the program for their needs," said Gold's Gym Fitness Service Manager, Brandon Gonzalez.
Brandon is the trainer Sarah Barter chose after having knee surgery.
"He was having me do things that were building the muscle around my knee, so I could trust it again," Sarah said.
Now, he's making her use almost every piece of equipment at the Gold's Gym Westlake location.
Brandon said, "She's one of my more dedicated clients."
Sarah chimed in, "Oh, my God. That was almost a compliment."
"Can't have her head getting too big," countered Brandon.
Sarah replied, "It wouldn't fit with yours already taking up all the space."
They've been training together for five months.
"I need someone who's gonna force me to do more than I think I can," she said. "I wouldn't do well with someone who's like, oh you can't, okay, let's lower the weight."
Still, not everyone responds well to being pushed to their limit.
Brandon said, "Half the job is managing personalities more than anything."
"He also doesn't know how to count," said Sarah.
He said, "She likes to cheat a rep or two."
Some people will try anything to lose weight and the latest smart phone app will actually insult you to get you to shed the pounds."
It's called Carrot Fit and it's a "judgmental weight tracker."
"It's entertaining," Brandon admitted. "I, personally, would never pay for and I would never encourage I know to pay for that."
"I could see maybe, yea, trying that out," Sarah said. "It would be like having Brandon on my phone."
Brandon added, "It would not be that way at all. See, I'm too easy on that girl."
Easy or not, Sarah's seeing the results.
She said, "I've just noticed the fat percentage loss and gaining muscle and feeling better and my clothes fitting better."
"I'm here to help guide them along the way, but I'm not trying to be that crutch," said Brandon.
