Before Anyone Believed in Conor McGregor He Believed in Himself

Mystic Mac. The Mac. The Notorious. The man who told a whole sport he was going to do something, then did it in front of them.

Two belts. A left hand that made arenas forget their manners. A walkout that turned a cage into a stage. The prediction, the suit, the stare, the finish.

By 27 he had the game in his hands. Featherweight Champ. Lightweight Champ. The Double Champ. The Floyd Mayweather night banked.

“At 27 years of age, I had the game conquered. I had the game wrapped up in a blink. What more was I to do? I got lost. I got lost in it.”

Then the star’s shine started to fade a bit . A leg that snapped against Dustin Poirier. A toe that pulled a date. Camps that started and stopped. A fanbase that kept pulling for him and waiting to see if the man still had it. In July 2026 The Mac walked out again, against Max Holloway, drilled, sharp, and certain. The first kick of the night took the knee. Sixty-nine seconds. ACL and meniscus. He called the head space hell. Then he posted the old creed, said he would be at church, and wrote the only line that fits the nickname now.

“On we go, no sad stories.”

The truth every athlete who has ever been the one eventually meets: you can do the work right and the night can still break. The faith he says turned a spark back into a blaze.

He said that. Then he went back to the gym.

Before the Nickname

He was 17 when his mother got him a trade. Apprentice plumber.

He told The Guardian what the job felt like. “It just wasn’t for me. I was waking at 5am and walking in the dark, freezing cold until I reached the motorway and waited for a guy I didn’t even know to take me to the site, where I worked for 12 hours and then got driven back and walked home. I know there are passionate, skilled plumbers. But I had no love for plumbing.”

He quit in 2008. He walked home and told his father there was not a hope he was going back to that site. They fought. His father won the fight. McGregor still did not go back. “I left and said, I’m going to pursue this dream of fighting for the UFC.” No Irishman had done it yet. There was no career he could point at and say, look, that is the path.

The early record was not great. He lost two of his first three professional fights. Then he hit a streak followed by Cage Warriors titles. Then, a UFC contract in 2013. The week before his debut in Stockholm, he was still collecting social welfare. He said it at the press conference after he knocked Marcus Brimage out in 67 seconds and picked up a $60,000 bonus.

“Just last week I was collecting the social welfare. I was in there saying to them, ‘I don’t know what’s going to happen. I’m signed to the UFC.’ Now I suppose I’m just going to have to tell them off. I’m making money here. I didn’t have money before this. I was collecting 180 euros a week off the social welfare and here I am.”

That is the story behind the nicknames. A trade he did not love. A decision to go all in on a sport that had no Irish chapter yet. Then a world title. Then two. And, that was just the beginning.

The CD That Taught the Notorious His Combinations

Before the belts, there was a voice on the radio at Straight Blast Gym. It’s a voice you might recognize.

In February 2019 McGregor trained at Bas Rutten’s Elite MMA. He stood in front of the original UFC heavyweight belt Rutten won, the first European to take one, and the Pancrase title under it. Then he got to the part that belongs in a training piece.

“Bas also had a training voice recording out, where he would call out MMA combinations and drills. My coach would play it on the radio and we would work. ‘Double knee, liver shot, 10 sprawls.’ Bas was the first person to teach me how to piece MMA style combinations together. And it was through a CD on the radio.”

He called Rutten a pioneer and a proper goer. Rutten has said since that McGregor posted about those old audio workouts, the ones pros and amateurs were already using. The system is simple enough to steal. A voice calls the work. You do not negotiate. You throw the combination, then the sprawls, then the next call.

That is a session an athlete can run without a cage.

Bas audio block, 20–30 minutes

Find space. No bag required. A partner or a timer calls:

Jab, cross, hook, sprawl

Double knee, liver-side kick or knee, 10 sprawls

Teep, cross, level change, stand back up

Three rounds of three minutes. One minute off. Hands up. Feet moving. When the call comes, the body answers before the head argues.

For the full version, Bas Rutten’s Fighting Machine workout turns those called combinations into a complete training system.

What the Gym Looked Like When He Was All In

John Kavanagh has been in the corner since the sport was a rumor in Ireland. His description of a locked-in McGregor day has stayed consistent. Two sessions. About 45 minutes each. In, intense, out. The lights go off. They do not hang around and talk the work into a smaller thing.

The plate was never a secret stack. McGregor told Men’s Health he did not eat takeaways. Good-quality meats. Good-quality greens. Good-quality carbohydrates, sweet potato and butternut squash. Kavanagh’s one-sentence version is the one to keep. If it had a face or it grew, it is mostly fine. Stay away from the processed stuff. For the Road House build the lifts stayed simple too. Deadlift. Squat. Bench. Extra shoulder work because a camera likes a shoulder. Low sugar. Macros. Steak and vegetables.

He has also owned fasted cardio for years. “I like running. I’ve been running my whole career. I always do fasted cardio. I like training on an empty stomach because it takes you someplace. Puts you in a different mindset. You’re in survival mode almost. You’re on the hunt.”

The Win That Got Him Lost

Conor McGregor has said a loss can make or break a fighter, and a win can do the same thing, because people get comfortable. “You sleep on a win and you’ll wake up with a loss.”

He has been plain about the rooms. He did not drink heavily when he was at the top. Then the product he was selling was in the house. He left with bottles under his arm and called it caught. He has said partying is weakness for the soul, and that the craft asks you to be a little gone to everything else. Athletes know a smaller version of the same week. The party after the big Saturday. The check. The group chat as the only coach left. The structure does not survive the celebration unless somebody puts it back on the calendar.

The Faith That Brought the Mac Back to the Work

The return was not only a gym story. In October 2025, at a bare-knuckle press conference in Rome, he said he was not in the room by chance.

“There is a higher power, God, that dictates my journey and all of our journeys. And I live my life by God’s word. I’ve engaged in a spiritual journey, and I am saved. I am healed. My competitive spark that was once in my heart is now a roaring blaze.”

He said he envied the fighters about to make weight, because they were about to do what they were called to do. “As am I called to do it. I had to dial myself in and go inward.”

Kavanagh, around the same stretch, said there had been a spiritual awakening and a different vibe. McGregor was back in the gym most mornings, early, and having fun with it. He asked for a program ramped toward a summer return. Some of the work at SBG. Some at a new setup at the house. Training partners requested. He said he was going to live at the gym.

Before the fight he sat with the cameras and did the harder interview. “You’ll always come home if you truly love something.” Then the line that belongs on a wall. “It’s day-by-day work. Day after day, you’ve got to put it in. The rent is due every day.” He compared it to a tightrope. Learn balance or one wobble takes you off. The rope gets thinner after you have already climbed, because the drop is heavier. People, places, things. Do not go back to the rooms that used to own you. “I still have work to do.”

After the loss he posted the Nicene Creed in full, the old confession of faith in the Father, in Jesus Christ, in the Spirit. He wrote that he is a child of God and a friend of God, and that God makes a way where there seems to be no way. He said he would be at church. “Church was intense today, my heart is heavy but through Christ my mind is strong.” The plan under the prayer was ordinary. Surgery. Prehab. Return to martial arts practice. Go again.

The Camp That Still Ended in 69 Seconds

The last fight was UFC 329, July 2026, against Max Holloway. First walk in five years. The last one, in July 2021, had ended with a broken leg against Dustin Poirier. A Chandler date in 2024 had died on a broken toe. This camp was supposed to be the clean one.

Kavanagh said the opening jump switch kick had been drilled daily for months, multiple times in warmup. Never an issue. McGregor said he was throwing kicks, planting and jumping, all through camp and backstage before the fight. Dana White posted warmup footage of the same kick. McGregor said he was sharp, calm, ready. “I had no injury going into the fight. This came out of nowhere.”

The first kick of the night buckled the right knee. Sixty-nine seconds. Injury TKO. ACL and meniscus, the same injury as his first Holloway fight, opposite leg. He called the head space hell. Kavanagh called it devastating. “Doesn’t get any worse than this.”

Then the line that makes the piece. McGregor wrote that he was at maximum discipline and had kept it since the bout. He wondered if he had been saved from something worse, an afterparty, an old room. “I believe I was saved. Thank you God.” He was walking without a crutch. He had done leg extensions. He pointed at a return the following summer. “Your health is your wealth.”

That is the message under the highlight. You can drill the kick for months. The knee can still go. Doing it right is not a contract with the outcome.

A Week You Can Run

Four days. Forty-five minutes. Then leave.

Monday, engine. Twenty to thirty minutes easy, run or bike or row, before the day argues with you. Then eight rounds of one minute harder, one minute easy.

Tuesday, strike and strength. The Bas block above. Then goblet squat, 4 x 6. Push-up or bench, 4 x 8. Row, 4 x 8. A carry. Out.

Thursday, hinge day. Deadlift or Romanian deadlift, 4 x 5. Shoulder press, 3 x 8. A core finisher. If a joint is angry, swap the pattern. Do not skip the room.

Saturday, long and easy. Forty to sixty minutes at a pace you could talk through.

Food: water before the first screen. Meat, greens, a potato or squash. Nothing that requires a drive-through voice on training days.

If one piece is hurt, train what is not injured, then get a real person to look at the piece. Pride is not a treatment plan.

Lines He Actually Said

“I had no love for plumbing.”

“Just last week I was collecting the social welfare.”

“Bas was the first person to teach me how to piece MMA style combinations together. And it was through a CD on the radio.”

“I got lost. I got lost in it.”

“You sleep on a win and you’ll wake up with a loss.”

“I live my life by God’s word. I am saved. I am healed.”

“The rent is due every day.”

“You’ll always come home if you truly love something.”

“I had no injury going into the fight. This came out of nowhere.”

“On we go, no sad stories. Your health is your wealth.”

Your Playbook

Leave the job you do not love only if you will accept the empty weeks that follow. All in is a calendar, not a speech.

Steal the CD. Let a voice call the combinations. Answer before you negotiate.

Short sessions, finished. Two focused blocks beat a three-hour hangout in gym clothes.

Eat food you can name. Meat, greens, a potato.

Do not sleep on the win. The party, the check, the deal, none of them pay the rent tomorrow.

If faith is the thing that got you back in the room, keep the appointment. Church, a quiet morning, a standard you do not break when the night goes wrong.

Drill the kick. Know the knee can still go. Surgery. Prehab. Practice. Go again.

Follow the calling. Focus on what got you here. Lock in. The outcome is not the promise. The next morning is.

The Notorious already had the highlight. What he did not have, for a long stretch, was a reason to be early. The nickname survived. The man had to earn it back one morning at a time, and then watch a drilled kick end the night anyway.

That’s life sometimes. No sad stories. It’s not always about the outcome. Take it from The Mac:

“Before they believe, you do.

I believed in myself before anyone had a reason to. I walked into the gym, put in the rounds, took the lessons and came back for more. That belief got me through the door. The work gave it weight.

You have something you want? Back yourself enough to begin. Then show up again tomorrow. Let them see it when they see it.”
