From 140 Pounds to Muscle: The Step-by-Step MMA Workout That Transformed Wiz Khalifa

He once joked about having "chicken legs," but years of dedication in the gym transformed the rapper into one of hip-hop's most unexpectedly muscular stars.

Wiz Khalifa was once known for his famously slim frame, but by 2022, the rapper had clearly entered a different era. In a video for Men's Health, he walked viewers through the MMA-style workout routine that helped him build strength and sharpen his focus.

"I'm just a passionate person," Khalifa shared. "Fitness, it was never a hobby or anything of mine, but it was something that I always looked at as important." Now, you can get a behind-the-scenes look at the MMA-style workout that helped fuel his physical transformation and reshape his approach to fitness.

Step 1: Stretch, Warm Up, and Prepare the Body

Before anything else, Khalifa warms up his body. "It doesn't matter which day it is, what muscle group we're working. We'll come in, we'll stretch out," he shared. From there, the routine moves into smaller warm-up exercises before the bigger movements begin.

That careful start matters because the rapper's workouts are not casual. His routine blends strength training with combat-style conditioning, so warming up helps prepare his body for both lifting and kickboxing.

By the time he appeared in the Men's Health feature, those jokes had been replaced by a clear commitment to building strength from head to toe.

It also sets the tone for a session built around control, movement, and endurance rather than simply trying to look good on camera.

Khalifa started taking training seriously around age 27 after joining a strong gym environment and surrounding himself with people who helped him understand his body. That was when fitness shifted from something he respected to something he committed to.

Step 2: Move Into the Main Lift

Once his body is ready, Khalifa moves into the main strength exercise of the day. If it is a leg day, the workout includes back squats or front squats. If it is a chest day, the focus shifts to bench presses. But during it all, the rapper did not pretend that part of the process was easy, as he joked:

"The results are me crying when I do that. I shed a tear every time."

The humor fits Khalifa's personality, but the message behind it is serious. He pushes himself until the set becomes difficult, and that is when he knows the work is paying off. That mindset also shows how far he has come.

Years earlier, the "Black and Yellow" rapper joked in another interview about letting his "chicken legs" out for the summer while getting them tattooed. By the time he appeared in the Men's Health feature, those jokes had been replaced by a clear commitment to building strength from head to toe.

Step 3: Train the Back With Rows, Pull-Ups, and Chin-Ups

After the major lift, Khalifa's routine can move into back work. His approach includes inverted rows, pull-ups, wide-grip movements, and chin-ups depending on the day. The rapper shared:

"I got a really wide [expletive] back for some reason. I don't know why, so it's good to work on it and just spread that out."

The back training gives his upper body more shape and strength, but it also supports the combat side of his routine. A strong back helps with posture, punching mechanics, pulling strength, and overall control, all of which matter once the workout shifts into boxing and kickboxing drills.

Step 4: Add 30 Minutes of Kickboxing

After roughly an hour of strength work, Khalifa moves into the MMA-inspired part of the session. The kickboxing portion lasts about 30 minutes and usually begins with shadowboxing, where he works on technique, rhythm, and footwork before moving into bag drills.

"You'll just shadow box, which is you kinda hitting the air and getting your technique right, getting your footwork together," he said. Once that foundation is set, trainers step in and guide him through rounds on the bags to build sweat, timing, and endurance.

Looking ahead, the rapper imagined himself at 50 with gray locks, tattoos, and an even stronger build, joking that he planned to keep adding muscle until he was "built like a house."

For Khalifa, the goal is not just to throw punches for fitness. His routine focuses on the difference between pad work and more realistic movement. "There's a difference between just hitting the pads and actually sparring and getting into real situations," he noted.

Step 5: Use Fitness to Clear the Mind

While his transformation is physical, the rapper has also made it clear that the mental benefits are just as important. Training gives him space to clear his head, think through ideas, and build relationships with people in the gym. He said:

"My main reason for working out now is I love the results. I love what it does for me mentally."

That point helps explain why the routine has lasted. Khalifa is not only chasing a more muscular body; he is building a structure that supports his work, creativity, and discipline. He also views training as a constant learning process.

"It's something that, when you're training, you're always picking up new methods or techniques. You keep hitting these milestones, and you keep just reaching points where the hard work pays off. And I love that feeling," he revealed.

Step 6: Keep Building for Life

Ultimately, Khalifa's fitness goals are not tied to one video, one transformation photo, or one phase of his career. He sees the process as long-term. "I think my goal is just lifelong," he said.

Looking ahead, the rapper imagined himself at 50 with gray locks, tattoos, and an even stronger build, joking that he planned to keep adding muscle until he was "built like a house."

That vision sums up the larger transformation. Wiz Khalifa did not simply go from slim to muscular; he changed the way he approached his body, his routine, and his mindset. The MMA-style training gave him a system, but the consistency made the difference.
