HIIT

As I've mentioned before, I've been a regular at the gym for a couple of years now.  My workouts are primarily HIIT (High Intensity Interval Training), which seemed to be unanimously agreed to be the best training method at both the AHS and Nora Gedgaudas’s recent seminar.

HIIT is designed to incorporate bursts of high intensity sprints with recovery intervals.  The sprint sections are typically 60 seconds or so, enough to use every last bit of stored energy in the muscles.  This is very different to “chronic cardio”, where hours can be spent in the gym mindlessly pounding the treadmill.  HIIT improves endurance, fitness, lean muscle mass and oxygen consumption (including after the workout, resulting in fat burning for hours after the workout).  Injury from over training is also a lot less likely with HIIT.

During the last two months of so, I've upped the number of HIIT sessions to three and am amazed at the difference in my fitness and strength.  I can’t wait to see how much fitter I’ll be in a few months time.  Before Paleo I went through phases of chronic cardio and never achieved anything like the results I am enjoying today.

I've been reading lots of differing viewpoints about eating post work-out, and am currently trying the not eating post workout approach.  The idea here is that after using up all of your stored energy your body has to use body fat – and as soon as you eat it will stop that process and start using the food as fuel.

I've read how our bodies are capable of so much more than our minds believe.  I've therefore been asking a lot of fit people how they deal with the mental aspect to training.  There seem to be a few approaches, such as only focusing on the next five reps (instead of the whole set), complete distraction by focusing on music for instance, or focusing on the end goal.  I'm going to try a few different approaches myself to see if changing my thinking can enhance my performance.

Training Smarter: Why Recovery Is Just as Important as the Workout

When it comes to high intensity training, the workout itself often gets all the attention — but what you do between sessions is just as important. Recovery allows your muscles to repair and grow stronger, while helping to regulate cortisol levels and reduce the risk of overtraining injuries. For those of us following a Paleo lifestyle, recovery should be about more than just rest — it should include proper sleep, real food, mobility work, and active recovery strategies.

Since HIIT places a high demand on your nervous system and muscle fibres, the temptation to train hard without pausing can backfire. By listening to your body and integrating restorative practices like walking, foam rolling, breath work and stretching into your week, you'll bounce back stronger and avoid burnout.

Fuel or Fast? Reassessing the Post-Workout Meal

One of the most debated topics in fitness is whether or not to eat immediately after a workout. In the Paleo world, the answer depends largely on your goals. If fat loss is your main focus, delaying your meal might extend the fat-burning window. This works especially well if your training is fasted and your body is already tapping into stored fat for energy.

However, if your goal is to build muscle or improve athletic performance, providing your body with high quality protein and carbohydrates post-workout can enhance muscle protein synthesis and speed up recovery. The key is to avoid processed shakes and instead focus on real food: think grilled chicken, sweet potato, or a boiled egg with a piece of fruit.

The timing and composition of your post-training nutrition should align with your body composition goals, energy levels, and how you respond to different eating windows. As always, experiment and observe how your body feels and performs under each approach.

The Mental Game: Strength Starts in the Mind

When it comes to HIIT and other demanding workouts, the psychological component often makes the difference between giving up and pushing through. Mental toughness is a skill, not a trait — and just like physical strength, it can be developed.

One technique many athletes use is called “chunking,” which involves mentally breaking the workout down into smaller, more manageable parts. Instead of focusing on the full 30 minutes of intervals ahead, concentrate only on the next round, the next rep, or even just the next 10 seconds. This reframing trick makes even the most daunting workouts seem more doable.

Another powerful mindset shift is to replace negative self-talk with encouraging mantras. Repeating affirmations like “I’m stronger than I think” or “just one more set” can quiet the inner critic that often sabotages progress.

HIIT at Home: No Equipment, No Excuses

One of the best aspects of HIIT is that you don’t need a gym membership or fancy equipment to reap the benefits. Bodyweight exercises like burpees, jump squats, high knees and mountain climbers can be combined into effective circuits that torch fat and build endurance in under 30 minutes. Perfect for busy days or when travelling.

If you want to step it up a notch, using a skipping rope, resistance bands or kettlebell adds resistance and variety without cluttering your living room. You can tailor each session to suit your space, time and current fitness level — and scale it as you grow stronger.

The Hormonal Impact of Intense Training

It’s easy to think of exercise purely in terms of calories burned, but training has a significant impact on your endocrine system too. Short, intense bursts of exercise help regulate insulin sensitivity and promote human growth hormone (HGH), a natural anabolic hormone that supports muscle repair and fat metabolism.

But intensity needs to be balanced. Overtraining, especially without sufficient sleep or nourishment, can lead to chronically elevated cortisol levels — a stress hormone that promotes fat storage (especially around the belly) and suppresses immune function. Rest days and active recovery are critical to keep your hormonal profile in check, particularly for women or those over 35.

Tracking Progress Without Obsessing Over Numbers

Progress in HIIT isn’t always about lifting heavier or running faster. Improvements in form, increased stamina, better recovery times and a stronger mindset are all indicators of success. Consider using tools like a fitness journal, heart rate monitor or performance-based fitness app to track your evolution — but don’t become a slave to numbers.

Your body is the best feedback tool. Are your clothes fitting better? Do you have more energy during the day? Are you sleeping more soundly? These are the metrics that matter most. Over time, they’ll tell you more than a scale ever could.

Supporting Your Fitness Journey with Paleo Nutrition

Your training and nutrition should work together, not against each other. A Paleo approach gives your body the building blocks it needs to recover, build muscle, and support hormonal health. Focus on anti-inflammatory foods like grass-fed meats, wild-caught fish, colourful vegetables, root starches like sweet potato, and healthy fats such as avocado, olive oil and coconut.

Stay away from post-workout “recovery” snacks that come in shiny packaging and are full of processed carbs and additives. Instead, plan ahead so you have something ready to refuel with if you choose to eat post-session. Even something as simple as a banana with almond butter can work wonders.

Keep Pushing Forward

Whether you're in your first week of HIIT or years into your journey, remember that consistency trumps perfection. You don’t have to smash every session or PR every lift. What matters is showing up, doing the work, and gradually raising the bar — physically and mentally.

Experiment with different techniques for motivation, recovery and fuelling your sessions, and stay curious about how your body responds. As you fine-tune your approach, your training will evolve into something sustainable, effective and enjoyable — not just another thing to tick off your to-do list.

And if you're still stuck in a chronic cardio rut or plateau, try trading one of those long jogs for a short HIIT session. You might be surprised by how quickly your body adapts — and how much stronger, fitter and more energised you feel.

What kind of workouts do you do?  I’d be really interested to hear how you approach the mind aspect of your workouts too.
