The Power of HIIT: Why This Workout Still Deserves a Place in Your Fitness Routine

Fitness loves a trend.

One year it’s HIIT. Then strength training takes center stage. Pilates explodes. HYROX arrives. Zone 2 becomes the phrase everyone is talking about.

And we’re here for it.

At SHRED, we’re big believers that the best fitness routine isn’t built around one discipline. It’s built around variety, consistency, and finding ways to move that you genuinely enjoy.

But amid all the new training styles competing for our attention, there’s one workout format whose value shouldn’t be forgotten: HIIT.

High-Intensity Interval Training may not be the newest acronym in fitness anymore, but there’s a reason it became so popular in the first place. It works. And perhaps more importantly for busy lives, travel schedules and people who don’t want to spend hours in the gym, it works efficiently.

Short bursts of effort, quick recovery, repeat — the simple structure behind HIIT.

So, What Exactly Is HIIT?

HIIT stands for High-Intensity Interval Training. The concept is refreshingly simple: alternate relatively short periods of harder effort with periods of recovery or lower-intensity movement.

Work. Recover. Repeat.

A HIIT workout might combine movements such as squats, lunges, push-ups, mountain climbers, burpees, resistance exercises or cardio intervals. The exact exercises can change almost endlessly. The important part isn’t a particular movement. It’s the change in intensity.

During the work intervals, you’re challenging yourself. During recovery, you give your body enough time to prepare to go again. That simple structure can create an incredibly effective workout without requiring an incredibly long one.

7 HIIT Workout Benefits That Still Matter

1. You Can Get a Lot Done in Less Time

This might be HIIT’s superpower. You don’t always need 60 or 90 minutes to have a meaningful workout. By concentrating periods of higher effort into a shorter session, HIIT can provide a substantial cardiovascular challenge in relatively little time.

That’s especially valuable when you’re balancing work, travel, family, surfing, social plans — or simply enjoying Puerto. A shorter workout is also easier to fit into real life. And the workout you actually do is infinitely more useful than the “perfect” workout you never have time for.

One of HIIT’s biggest advantages: getting a meaningful workout done without spending hours training.

2. HIIT Challenges Your Cardiovascular Fitness

Your heart is working too. Repeated higher-intensity intervals challenge your cardiovascular system to deliver oxygen to working muscles and recover between efforts. Research on HIIT has associated the training style with improvements in aerobic and anaerobic fitness and cardiovascular health.

That’s part of why HIIT can complement so many other activities: surf, run, cycle, HYROX, hike, play sport — or simply feel fitter moving through everyday life.

3. It Trains Your Ability to Recover

One of the most interesting things about HIIT isn’t just learning to work hard. It’s learning to recover and go again. Your heart rate rises. You breathe hard. You recover. Then you ask your body for another effort.

There’s a mental component too. You learn that discomfort is temporary. You catch your breath. Then you’re ready for the next round.

The community factor matters too — working hard is easier when you’re doing it together.

4. HIIT Can Be a Full-Body Workout

HIIT isn’t synonymous with endless burpees. A well-designed class can incorporate lower-body strength, upper-body strength, core stability, cardio, balance, coordination, agility and functional movement.

Bodyweight exercises, resistance bands, dumbbells and other equipment can all be incorporated. Change the movements, timing, equipment or work-to-rest ratio and you’ve created an entirely different workout while keeping the same underlying training principle.

Mountain climbers are just one of many movements that can be incorporated into a varied HIIT workout.

5. HIIT Can Support Metabolic Health

HIIT’s benefits aren’t limited to how sweaty you get. Research has linked HIIT with improvements in insulin sensitivity and other markers of cardiometabolic health. That’s an important reminder that the value of exercise extends far beyond calories burned or what you see in the mirror. Movement is an investment in health.

6. HIIT Can Meet You Where You Are

“High intensity” doesn’t mean everyone has to move at the same speed. Intensity is personal. An interval that challenges someone taking their first fitness class will look different from one that challenges an experienced athlete.

Movements can be modified. Impact can be reduced. Resistance can change. Pace can change. Recovery can change. The objective isn’t to compete with the person beside you. It’s to find an appropriate level of challenge for your body today.

HIIT doesn’t have to mean competing with everyone around you — the goal is finding your own appropriate intensity.

7. And Yes… HIIT Can Actually Be Fun

This part gets overlooked in conversations about VO₂ max, heart rates and work-to-rest ratios. A great HIIT class has energy. Music is playing. People are moving together. Someone beside you is encouraging you through the final seconds. The instructor calls time. Everyone laughs. And somehow, you’re already thinking about doing it again.

At SHRED, that’s a big part of why we still love HIIT. Because enjoyment matters. The most scientifically optimized workout in the world isn’t particularly useful if you hate it enough to stop doing it.

HIIT can be challenging, adaptable and social — fitness works better when you actually enjoy showing up.

But Is HIIT the “Best” Workout?

No. And that’s actually the point. HIIT is a tool — a very effective one — within a much bigger fitness toolbox. Strength training matters. Mobility matters. Cardiovascular endurance matters. Recovery matters. Yoga matters. Rest matters. And different bodies, goals and stages of life require different things.

At SHRED, that’s exactly how we think about movement. You might do HIIT one day, yoga the next, strength or HYROX another day, Pilates later in the week and give yourself time to recover somewhere in between. Variety doesn’t diminish HIIT’s value. It makes HIIT more valuable because it has a clear role within a balanced routine.

HIIT Isn’t New. That’s Kind of the Point.

Fitness culture moves quickly. New disciplines emerge. Old ideas get new names. Training methods move in and out of the spotlight. And that’s exciting. Trying something new can be one of the best ways to rediscover motivation.

But newer doesn’t automatically mean better. HIIT has survived the fitness trend cycle because its underlying idea is remarkably straightforward: Work hard. Recover. Repeat.

It’s efficient. It’s adaptable. It’s challenging. It’s accessible. And it can make you fitter. Sometimes the fundamentals don’t need reinventing. They just need remembering.
