People look at my body and assume it was built in a mirror. The truth is less glamorous. My base was built in a boxing gym, years before I ever stood in front of a camera. In July 2009, at 16, I won the gold medal at the Spanish Cadet Boxing Championship in Pedrezuela, Madrid, fighting at super welterweight, under 69 kilos, for the Valencian team.

I am not going to pretend that a cadet title makes me a coach. It does not. But boxing gave me a way of thinking about fitness that I have never dropped: you train in rounds, you rest briefly, and you go again. That rhythm builds the kind of conditioning that carries over into everything, including a job where stamina matters a lot.

I am not a doctor or a certified trainer, and this is not medical advice. If you have heart problems, high blood pressure, joint injuries or you have not trained in years, talk to a doctor before starting. The facts below come from the American College of Sports Medicine (ACSM), the NHS and peer-reviewed research. The opinions are mine.

Why boxing conditioning works: the science of rounds

A boxing round is three minutes of work followed by one minute of rest. Amateur bouts are short, intense and repeated. Without calling it that, boxers have been doing interval training for a century.

Interval training means alternating periods of hard effort with periods of easier effort or rest. The modern version, high-intensity interval training or HIIT, has been studied a lot. A 2015 systematic review and meta-analysis in Sports Medicine by Milanovic and colleagues compared HIIT with continuous endurance training, the classic steady jog. Both improved VO2max, which is the best single measure of how well your heart, lungs and muscles use oxygen. HIIT produced slightly larger improvements (Milanovic et al., PubMed).

Another review, in the British Journal of Sports Medicine, looked at HIIT in people with lifestyle-related heart and metabolic disease, the conditions so many men drift into in their thirties and forties. HIIT improved cardiorespiratory fitness significantly more than moderate continuous training in those patients (Weston et al., PubMed).

Why does VO2max matter so much? Because fitness is not only about looking good. A large Cleveland Clinic study published in JAMA Network Open followed 122,007 adults who did treadmill tests. Higher cardiorespiratory fitness was linked with lower long-term mortality, with no upper limit of benefit, and the researchers noted that poor fitness carried a risk comparable to or greater than traditional risk factors like smoking and diabetes (Mandsager et al., PubMed).

Muscles get you noticed. Conditioning keeps you in the game.

The four pillars of a boxer’s fitness

When I break down what boxing actually trains, I see four things. Every good session should touch all of them.

1. Aerobic base. The engine. Long, easy work like running or steady skipping builds the ability to recover between hard efforts. Boxers do roadwork for a reason.
2. Anaerobic power. Short, explosive bursts: a flurry of punches, a sprint, a hard round on the bag. This is where intervals come in.
3. Muscular endurance and strength. Holding your hands up for three minutes is harder than it looks. Shoulders, core and legs have to keep working when they are tired.
4. Coordination and footwork. Balance, rhythm and moving your body as one unit. This is the part gym machines never teach you.

Most men who train only do one of these. The bodybuilder trains strength. The jogger trains the aerobic base. Boxing forces you to do all four, which is why boxers tend to be fit in a very complete way.

Skipping: the most underrated tool in the gym

If I could give every man one piece of equipment, it would be a skipping rope. It costs almost nothing, fits in a bag and trains calves, shoulders, timing and the cardiovascular system at the same time.

Start simple. Two-footed bounce, small jumps, wrists doing the work, not your arms. Do three rounds of two minutes with one minute rest. When that feels easy, move to three-minute rounds and add alternating feet, like light running on the spot.

Skipping is a high-impact activity, so build up slowly if you are heavy or have knee, ankle or Achilles problems. A good surface, like a wooden gym floor or a rubber mat, is much kinder to your joints than concrete.

Shadowboxing and bag work without the head injuries

You do not need to get hit to get fit like a boxer. Sparring is a skill of its own, and repeated blows to the head carry real risks. If you ever want to spar, do it in a proper club, with a qualified coach, headgear, gloves of the right weight and partners who are there to learn, not to hurt you.

For fitness, the two best tools are:

• Shadowboxing. Throwing punches at the air while moving your feet. It looks simple and it is exhausting if you do it properly. Keep your hands up, your chin down, and move after every combination.
• Bag work. A heavy bag lets you punch with power. Wrap your hands and wear bag gloves to protect your wrists and knuckles. Focus on technique first: a punch comes from the legs and hips, not just the arm.

If you are new, a few lessons with a boxing coach are worth more than any online video. Bad technique on a bag is how people hurt their wrists and shoulders.

Strength for boxers, not bodybuilders

The NHS recommends that adults do strengthening activities that work all the major muscle groups on at least two days a week, on top of their aerobic activity (NHS physical activity guidelines). The ACSM’s guidelines say the same (ACSM physical activity guidelines).

For a boxing-style approach, I prefer movements that make the body work as one piece:

• Squats and lunges for the legs that drive every punch.
• Push-ups and overhead presses for the shoulders that keep your guard up.
• Rows and pull-ups to balance all that pushing.
• Planks, side planks and rotational movements for the core.
• Farmer’s carries, walking with heavy weights, for grip and posture.

How much volume do you need to build muscle? A 2017 meta-analysis by Schoenfeld and colleagues found a dose-response relationship: more weekly sets per muscle group led to greater muscle growth, with 10 or more sets per muscle per week producing larger gains than fewer than five (Schoenfeld et al., PubMed). You do not have to chase huge numbers. Two well-planned full-body sessions get most men a long way.

A full 45-minute boxing workout you can do this week

Here is a session for a healthy adult with some basic fitness. If you are a beginner, cut the rounds in half and take longer rests.

Warm-up, 8 minutes. The NHS recommends warming up to raise your heart rate and loosen your joints before exercise (NHS: how to warm up). Easy skipping for three minutes, then arm circles, hip circles, leg swings, and two minutes of slow shadowboxing.

Skipping, 3 rounds. Three minutes on, one minute rest. Moderate pace, steady breathing.

Shadowboxing, 3 rounds. Three minutes each. Round one: jab and footwork only. Round two: jab, cross, hook combinations. Round three: everything, at a higher pace. One minute rest between rounds.

Bag or fast intervals, 4 rounds. If you have a bag: 30 seconds of hard punching, 30 seconds of light punching, repeated for three minutes. If you do not: 30 seconds fast shadowboxing, 30 seconds of squats or burpees. One minute rest between rounds.

Strength circuit, 2 rounds. 10 to 15 push-ups, 15 squats, 10 rows per side with a dumbbell or band, 30-second plank. Minimal rest between exercises, two minutes between rounds.

Cool-down, 5 minutes. Slow walking, deep breathing and gentle stretching of shoulders, chest, hips and calves.

That is about 45 minutes, with roughly 20 minutes of genuinely vigorous work. Do it two or three times a week, add one or two easier cardio sessions, and you are comfortably inside the NHS and ACSM recommendations of 150 minutes of moderate activity or 75 minutes of vigorous activity per week.

How to progress safely

The fastest way to stop training is to get injured in week two. Progress one thing at a time:

• Add rounds before you add intensity. Go from three rounds to four before you try to punch harder.
• Shorten rest slowly. From 60 seconds to 45 seconds over several weeks.
• Respect soreness. Some muscle soreness a day or two after a new workout is normal. Sharp pain, joint pain or pain that does not ease is not. The NHS advice on sprains and strains is a good starting point if you tweak something.
• Recover properly. Training is the stimulus. Recovery is where you adapt. I wrote a full guide on rest days and overtraining.

Mistakes I see men make

Training only the mirror muscles. Chest and arms, no legs, no cardio. You end up looking strong and gasping after one flight of stairs.

Going all-out every session. Intervals work because the hard parts are truly hard and the easy parts are truly easy. If every session is a war, you burn out.

Ignoring technique. Bad punching technique hurts wrists, elbows and shoulders. Learn the basics from a real coach.

Forgetting what comes after the gym. Food and sleep decide whether training makes you better or just tired. Read my guides on how much protein you need and how much sleep men really need.

Why this matters beyond the gym

There is a reason I put a fitness section next to my guides on sexual performance. The same arteries that feed your heart feed your erections, and the research linking regular aerobic exercise with better erectile function is solid. I covered it in detail in exercise and erectile function. Conditioning also helps with something every man worries about at some point: stamina in bed. Fitness is not the only factor, but it helps, and I explained the rest in how to last longer in bed.

My take

Boxing taught me that the body does not care about your excuses. It responds to work, rest and repetition. Three minutes on, one minute off, again and again, for years. That is not glamorous, and it is exactly why it works.

You do not need to become a fighter. You do not need to spar. But if you want a body that performs, not just one that poses, train like a boxer: skip, shadowbox, hit a bag, lift with your whole body, and respect your rest. Start with what you can do today and add one round at a time.
