A new workout partner?

"Hi there Vixxen," Robert said with a warm smile, "Always good to see young people staying fit." Robert was not a young man, but he was a very fit man. Not the sort to run marathons and stay thin, he looked very good for his age. He stayed fit in the gym, he had a good muscular build for his age.

Other than grey hair and a bald spot, Vixxen could not have guessed his age. Vixxen didn’t know, but he had to be in his sixties.

"I never got into yoga, my knees are shot, and I have a hip that just never played ball with me," Robert said as he walked past, she knew he noticed her boobs, but he did not leer and moved right on by. She spent more time looking at his arms than he had her boobs in fact.

Vixxen came out of her pose, leaned into the kitchen and grabbed a water bottle. "How can you keep muscle like that Mr. B? I lift at the gym and I do not see anything for it." Vixxen asked the older man, "If anything I am losing muscle, my ass is getting smaller."

Nikki's dad just smiled "I don't know Vixxen. Genetics are important, diet matters a lot, how I lift really, it's as good as I can expect it at my age. Really it is mostly about how you eat, compared with how you work out." Robert continued to try to educate Vixxen on proper diet for working out, depending on goal BMI and in general lost her pretty quickly.

Robert glanced at her ass, "You still have decent muscle mass Vixxen," the older man continued, somehow not being creepy about checking out her ass.

"Yoga is good, but don't get too thin Vixxen, you don't need to try to get skinny like those model types," Robert said to Vixxen as she listened intently. "I would suggest more weight, fewer reps, squats and abdominal work and more protein. A lot more protein.”

“I need to eat more? I’m not trying to get fatter!” She replied, drawing a hearty laugh from the older man.

“You aren’t fat darling, not even close to it,” he replied gently. “And it matters what you eat, I said you need more protein. Good protein.”

She asked about paying for a trainer, and he told her it was as big a waste of money. As was paying for the gym she had a membership at. "The trainers do not know much more than you do, you don't need them."

In the end, he offered to let her work out for free at his house when she wanted to and offered to train with her. "What I have is more than enough, equipment wise, you don't need to throw your money way sweetie. And I can teach you how to eat if you like.”

Nikki's dad had a warm smile, said goodbye without making a show of it and headed for the door. "Do not just eat salad Vixxen," He said when he got to the door. "Find a protein that you like, a low-fat protein. Chicken, salmon, cod, boiled eggs, maybe even protein shakes."

Vixxen gave him an odd look. Her stepdad had called her fat all the time, how did eating more help with that? "Give me time Vixxen," Nikki's dad responded. "You will understand where I am coming from, I promise you."

After this, the next day, in fact, Vixxen started going to Robert's house to work out, and she saw results faster than she would have thought. At first, it was soreness, but soon she started seeing muscle definition where she had not before.

Vixxen started to notice her shoulder muscles and triceps start to pop. Then her thighs and calfs started to get more defined, and eventually, she saw her abs start to show up. Through all of it, he had her doing a lot of squats and lunges, and her ass toned and grew. Less fat than before, her ass was really something to see in her hooters shorts.

It was big and round when she was young, and it had some muscle, but now it was really starting to have a muscular tone in addition to the size and roundness.
