Male Muscle Growth Story Novels & Stories

“Now you’ll have them shaking in their boots!” “In their cleats,” he corrected. “Alright what’s next on the list?” For the next twenty minutes, we worked through the athletic performance checklist. We tested how many push-ups and sit-ups he could do before he burned out. We timed his 100 yard sprint. The entire time, we joked around and teased one another. Between this and the night back at the MMA cafe, it felt like we were friends again. The last measurement was muscle growth. I needed to wrap the measuring tape around his arms and legs to see how much they had grown in the last month.

Like, stared with her mouth hanging open; stared with her eyes blinking stupidly. Nick had always been a huge, muscular guy. For as long as Mia had known him, he’d been physically active, and he’d worked out religiously and ferociously… but it was now clear to Mia that the upper body strengthening workouts he was doing in his physio were having a major impact on his body. The man was way more muscular, way more ripped, way bigger. Her response to all that male power and strength was automatic and it was helpless: her stomach clenched and her pussy fluttered.

The warmth of the water made my muscles feel relaxed, and before I knew it, I had spent half an hour inside. Looking in the mirror, I noticed that my arms and legs that had been spindly all my life, had started showing some signs of muscle growth due to the rigorous training routine. The bruises on my torso and upper thighs from the sharp kicks had begun to fade away, restoring my milky white skin to its original appearance to some extent. My curves had also started to appear fuller, after my waist and core had gained some definition. I was busy gazing at myself, analyzing the changes, but just when my eyes caught on my scar that stood out against my skin, I heard the sound of footsteps in t

Axel shot him a sidelong glance, smirking. “You’re holding back,” Axel grunted, raising his own weights effortlessly. “You keep hesitating like that, and you’ll never build strength.” Gavin exhaled sharply, setting the weights down with a thud. “Easy for you to say. You’re built like a damn tank.” Axel chuckled, switching to a heavier set. “Muscle’s just the byproduct. It’s discipline that counts. If you can’t focus, you’ll just end up hurting yourself.” Gavin wiped his hands on a towel, trying to mask his frustration. “It’s not about focus. It’s... I’m not used to this. My body’s still sore from yesterday.”

My entire day revolved around two things: meals that would help me gain weight, and exercises that would build my muscle strength. And, somehow, it was working, at least on paper. After all the eating, the training, and the struggling, I had managed to put on seven kilograms. At five feet five inches tall, I was now almost fifty kilograms. It was a small victory, but a victory nonetheless. To me, though, it didn’t feel like much. I saw myself every day in the mirror, same face, same body, so I didn’t notice the changes as much. But they were there.

He said with a smug grin. I shook my head and smiled a little. I am not used to having casual time with men, anytime at all. So my brother's way of saying things like that was new to me. “For my size,I think I can. I was more concerned when I dated Leo. Leo has a fit, but slender build. So at times I worried I might be heavy for him. Marcus was a big person even before he transformed himself. His body was meant to be large, so he replaced fat with muscle. So which makes him huge. He’s obsessive about fitness and health.”

~Kai Ten days had passed again, making it almost 25 days back from the hospital. My life had turned into a strict, repetitive cycle, wake up, train hard with Rhea in the basement gym, eat, shower, sleep… and repeat. No parties. No girls. No distractions. And it was working. I was gaining real muscle, not just for show, but functional, strong muscle. My shoulder wound had fully healed, the scar still pink but no longer painful. I could throw punches without wincing. My stamina was better. I felt sharper. Stronger.

I knew then that a man with his level of drive would be incredibly easy to rile up. Clyde complained, saying, "It was fine at the beginning of our relationship, but recently—maybe from all the protein powder—I've had a second growth spurt. It's grown so much that Yvonne just can't handle it anymore." I was stunned to hear him say he was going through a second growth spurt. I had heard some men could still develop after 25, but I had never heard of men growing in that aspect. I glanced inquisitively at his crotch, noting the significant bulge. I couldn't help but wonder if he was truly that big.

It just made him want more in life. His lighter hair and lighter eyes almost matched hers in color. He tried to work out a few times a week. Keeping weight on his lanker frame was hard enough, but he had built up a good amount of muscle as well. He had tried to bulk up, but that wasn’t the way to continue for him. He was finally comfortable in his own skin now.

I didn't like how everyone watched me like I was about to Hulk smash the building or something. Sure, I have to duck to go through doors and bend my knees to get under the shower spray, but I'm not a monster. The problem is that I'm not just tall, I really am built like a beast. I've got a wide body with thick arms and legs and I'm probably the strongest man in the world. I lift weights but nothing too crazy. My body just wants to be big, so I could pick up a bag of flour and gain muscle.
