5 HIIT Workouts You Can Do RIGHT NOW To Incinerate Fat In Under 15 Minutes
Cardio fiends, welcome to an explosive new world.
It’s called HIIT—or High Intensity Interval Training—and if you’re unaware (you really shouldn’t be at this point), it’s about to rock your naive little definition of cardio. We’ve already covered the magical, body-transforming powers of HIIT in-depth over here. Read that first, especially if you’re new.
But if you need a quick little refresher course, here’s the rundown of its uber-potent benefits.
- HIIT incinerates body fat. And unlike distance endurance cardio, it effectively preserves muscle tissue.
- AFTERBURN. HIIT elevates metabolism, increases the rate of fat burn (i.e. fat oxidation), and boosts O2 consumption for up to 48 hours post-workout (otherwise known as EPOC). Your body burns MORE without doing anything extra.
- It’s a significantly FASTER, more efficient form of cardio. That means less time maniacally glued to a treadmill.
- Improves VO2 max, which is the predominant marker of cardiovascular fitness. HIIT grooms the body to excel at endurance running, without ever running distance during the training phase.
- Depending on the mode, it can help build lower body muscle tone and stamina. Both of those are critical for sports and ultra-events like marathons, Spartan Races, and Tough Mudders.
- HIIT develops burst, power, and explosiveness.
- Helps nearly all markers of health, including insulin sensitivity and blood pressure.
And if that bulletin board isn’t enough to convince you, here’s a single fact that’ll suck you in immediately. Interval training produces more than TWICE the fat loss in HALF the time.
In one study that spanned 6 weeks, three 27-minute HIIT workouts per week reduced body fat by an average of 12.4%. Over the same period, anyone who was unlucky enough to do 60 minutes of steady state cardio, 3x per week, only lost a meager 5.8% body fat.
Point is — you can build and maintain a lean, ripped-up, ab-happy physique without indulging mind-numbing distance cardio. You just need to a little HIIT in your life; for as little as 15 minutes per session, a few times per week. When it comes to zapping stubborn body fat and dipping into the single digits (or mid-teens for women), there’s nothing more effective.
It’s that potent, sans hyperbole.
Ready to get moving? We’ve lined up 5 killer, multi-terrain HIIT cardio workouts to slash body fat and recompose your body from the inside out. Each protocol is designed to be short, brutally intense, and pushed to the max — it doesn’t work otherwise — but you’ll be done before your mind can even catch up with your body. And if you’re bored or underwhelmed, you’re doing it wrong. PUSH HARDER.
Pick your poison.
5 HIIT Workouts You Can Do RIGHT NOW To Incinerate Fat
HIIT performs best 3-4x per week, after a resistance training workout. Take 1 day off in between sessions.
For each workout, push yourself as hard as possible. But do it within reason — HIIT is an advanced technique that’s extremely taxing on the body. If something’s in pain or you’re overly winded, stop or slow down.
Just like you would with weights, start off a little conservative and gradually crank up the difficulty. This is power lifting for your heart.
HIIT Workout 1 — Treadmill Intervals
Use distance as a guide. During WORK intervals, sprint as fast as you can.
What we’ve laid out is a MODEL to guide you. Pick a sprint speed that’s challenging, but make sure that you’re able to sustain it for the full .15 mile interval duration. Be careful with higher speeds — the treadmill will continue to move with or without you.
We recommend starting off slower and working your way up. Sprint speeds in the 11-12.5 MPH range are ultimately your goal. Altogether it should mirror a pyramid. The middle two intervals will be the fastest, with the first/last 2 slightly slower.
HIIT Workout 2 — Spin Bike Intervals
For version 2, use a spin bike. It includes 3 cycles, for a total of 13 minutes. Time is your guide. Unlike the treadmill, intervals follow a Tabata style cadence — they’re designed to be short, quick-hitting, and performed at MAX intensity. Longer recovery periods are baked-in between cycles.
During each WORK interval, pedal standing up and max out RPMs. That means pedal as fast as humanly possible. This provides a variable version of HIIT that thrashes the quads, hamstrings, and glutes. You can also add a few turns to the resistance knob to crank it up even further.
If you don’t have access to a spin bike, a stationary bike also works. Adjust the resistance setting if standing isn’t an option.
HIIT Workout 3 — Beach Wind Sprints
This seems lovely, right? Wait until after a session.
Doing HIIT on the sand is both a glorious and brutal form of torture. It’s excruciatingly difficult, and your heart will feel like it’s going to palpitate out of your chest. Set-up by finding two landmarks on the beach. They can be flags, steps down to the beach, buildings, lifeguard huts, or palm trees. Cones and beach chairs work, too. This is your interval length.
- (1) Sprint as fast as possible from one point to the other.
- (2) Walk back to the opposite side.
- (3) Continue to repeat. Your workout should run ~ 15 minutes.
An average beach HIIT session includes roughly 10 intervals, but that’ll vary based on your interval distance (and recovery period). Experiment with different lengths to constantly vary your workouts. Floating in the ocean after is highly encouraged.
HIIT Workout 4 — Track Sprints
A running track is a great outdoor HIIT option that automatically modulates interval times. Timing is simple and baked-in, naturally:
- (1) Sprint the straightaways as fast as possible.
- (2) Walk the curves.
- (3) Continue to repeat the same cadence for a total of 2 miles.
That’s 8 laps, or 16 sprints. Take a walking recovery lap after the 1 mile mark (from 1 – 1.25 miles). Push yourself as hard as possible, but don’t be surprised if your body starts to wilt during mile 2. Completing the workout in a blazing fury is incredibly difficult.
HIIT Workout 5 — Hill Sprints
Hills — and bleachers or stadium steps — significantly amp up the difficulty by adding an incline, which helps produce lower body power and acceleration. Just like with the track, hills have a built-in interval cadence:
- (1) Run up as fast as possible.
- (2) Walk down.
- (3) Continue to repeat. Your workout should run ~ 15 minutes.
Bigger hills extend each interval (both work AND rest), whereas shorter hills keep them quick and intense. Experiment with different types to keep your workouts constantly fresh.
Try not to use a mountain, though. Look for a hill that you can ascend in less than 30 seconds.
