Why Cardio Training Still Reigns Supreme (Yes, Even in 2025)

Let’s be honest — cardio doesn’t always get the love it deserves. It’s the broccoli of the fitness world: undeniably good for you, but not everyone gets excited about it. Still, whether you’re into lifting heavy in the gym or training for a Hyrox event right here in Hammersmith, cardiovascular training deserves a firm place in your weekly routine.

Luke Kelly Personal Training

At Luke Kelly Personal Training, based in the heart of Hammersmith, we see it all the time — clients crushing strength goals but forgetting that their heart is a muscle too. And just like any other muscle, it needs work. That’s where cardio comes in.

So, why is cardio so crucial?

First off, it’s your body’s way of keeping the engine running smoothly. Cardiovascular exercise strengthens your heart and lungs, improves circulation, and boosts your endurance — all things that help you train harder, recover faster, and live longer.

But that’s just the sciencey part. In real-life terms, it means walking up the stairs without getting winded, chasing after your kids without needing a breather, or smashing through your next Hyrox workout without hitting the wall halfway through.

Whether it’s a steady run along the Thames, a HIIT session in Ravenscourt Park, or a fast-paced circuit at our Hammersmith studio, the key is consistency. And no, cardio doesn’t have to mean hours on the treadmill. It could be anything that gets your heart rate up — think kettlebell swings, sled pushes, rowing intervals, or good old-fashioned hill sprints.

At Luke Kelly Personal Training, we help you weave cardio into your training in ways that make sense for your goals. Want to burn fat, build endurance, or simply feel more alive? We’ve got the tools (and the playlists) to make it happen, right here in W6.

Bottom line: don’t skip cardio. Your heart — and your future self — will thank you for it. And if you’re around Hammersmith and need expert guidance, you know where to find us.
