The Rise Of The Hybrid Athlete
THE GAINS HUB #017
Reading Time: 5 minutes
There was a time when fitness made you pick a side. You either spent your evenings in the weights room trying to get bigger and stronger, or you owned a suspicious number of pairs of running shoes and willingly spent Sunday mornings covering distances most people would rather drive. Doing both wasn't unheard of, obviously, but it wasn't particularly fashionable either.
Now it has a name. The hybrid athlete is everywhere, combining strength training with running, cycling or other endurance work rather than specialising entirely in one or the other. HYROX events are selling out, running clubs are full of people who also lift several times a week and plenty of gym programmes now include conditioning without treating twenty minutes of cardio as something capable of immediately evaporating your muscle.
It's easy to dismiss some of that as another fitness label we've invented for something people were already doing, and there's definitely an element of that. Plenty of rugby players, boxers, CrossFit athletes and people training for military fitness have combined strength and endurance for decades without updating their Instagram bio to announce it. What's changed is how appealing that combination has become to ordinary people who aren't training for a particular sport.
For years, gym culture tended to push people towards fairly narrow definitions of being fit. If building muscle was the goal, cardio was often kept to a minimum, partly because people worried it would interfere with their progress and partly because spending forty minutes on a treadmill isn't particularly attractive when you'd rather be lifting. Runners could be equally protective of their mileage, worrying that extra muscle would slow them down or that sore legs from squats would wreck the next day's session.
Neither concern is completely invented. Strength and endurance training create different demands on the body, and doing large amounts of both can make recovery and programming more complicated. If your only ambition is to become an elite marathon runner, your training probably shouldn't look like somebody preparing for a powerlifting competition, while somebody trying to maximise strength doesn't need to squeeze a half marathon into every Sunday morning.
Most of us aren't trying to become elite at either, though, and that's where hybrid training starts making considerably more sense.
You can build muscle and still improve your 10K time. You can train for a half marathon without abandoning the weights room for three months, and getting stronger can actually be useful for runners rather than something they need to avoid. The challenge isn't deciding whether strength and endurance are allowed to exist together, it's managing enough of both without turning every week into a logistical nightmare.
That might explain why the hybrid idea has landed so well. For a lot of people, looking fit is no longer quite enough on its own. They want to be able to do something with it too, whether that's running a decent 5K, getting through a HYROX, hiking all day on holiday or agreeing to a charity race without immediately wondering what they've done. Equally, runners who once measured progress almost entirely through pace and distance are increasingly interested in being stronger and more physically capable away from running.
HYROX has probably given the trend its most visible home. Running sits between functional workout stations involving sleds, rowing, lunges, carries and other movements that reward a mixture of endurance and strength, so turning up with an enormous engine but very little strength can hurt just as much as arriving strong enough to move everything but unable to recover between stations. It packages the whole hybrid idea into something competitive, measurable and, importantly, accessible enough that normal gym members can imagine entering one.
Running's resurgence has helped as well. The sport has become noticeably more social and culturally relevant, with running clubs, big city races and brands attracting people who might never have considered themselves traditional runners. Once running stops feeling like an entirely separate fitness identity, adding a couple of runs to a week that already contains gym sessions doesn't seem particularly strange.
The internet inevitably makes hybrid training look more complicated than it needs to be. You don't need twelve sessions a week, a lactate monitor and a spreadsheet that requires its own induction course. For somebody who simply wants to become stronger while improving their fitness, a few sensible strength sessions alongside a couple of runs can already achieve plenty. The exact balance depends on what you're currently prioritising, because hybrid doesn't have to mean giving every part of fitness exactly the same attention.
There will also be weeks when one side wins. Training for a race might temporarily increase your running volume, while a period focused on gaining strength could mean endurance work takes more of a supporting role. Trying to push every lift, every running distance and every pace forward simultaneously is where a flexible approach can turn into an exhausting one.
Recovery matters for the same reason. A hard interval session and heavy leg training both count as demanding work even though Strava and your gym app might file them under different headings. Stack everything together without thinking about it and your legs won't care that technically Wednesday was “cardio”. Sleep, food and genuinely easier sessions become more important when you're asking your body to adapt in several directions at once.
Perhaps the most interesting thing about the hybrid trend is what it says about how our definition of fitness is changing. Being the strongest person in the room or the fastest person at the running club will always appeal to people who enjoy specialising, but plenty of us would happily trade being exceptional at one thing for being pretty capable at lots of them.
Which makes the slightly ridiculous part of the whole trend quite fitting: we've created a new name for lifting weights and doing some cardio.
Still, if calling yourself a hybrid athlete gets you out for the run and keeps you lifting, there are considerably worse fitness trends to get caught up in.
Supporting Your Goals
Training across strength and endurance means the basics matter more, not less. Eating enough to support your training, getting sufficient protein and paying attention to recovery will generally do more for you than building an enormous supplement stack around every different type of session.
For those who do supplement, creatine, protein and electrolytes can all have practical roles depending on your training, diet and individual needs.
