HIIT (High-Intensity Interval Training) classes are short, intense, and wildly effective. But they’re also incredibly demanding pushing your heart, muscles, and energy systems to the max in under 45 minutes. That kind of effort requires more than just showing up with sneakers and a sweat towel. To get the most out of HIIT, your body needs targeted fuel before you train and serious recovery support afterward.
In this article, we’ll walk through what to take before and after a HIIT class, which supplements actually help, and how to support your hydration, strength, and muscle repair with one clean formula.
Key Takeaways
- Before HIIT, fuel your body with electrolytes for hydration and creatine for strength.
- After HIIT, support tissue repair with collagen, and rehydrate with electrolytes.
- Harlo’s 3-in-1 formula makes pre- and post-class nutrition simple, clean, and effective.
- Avoid sugary, artificial sports drinks that spike energy then crash it.
- Whether you're training for performance or consistency, Harlo helps you recover faster and move better.
Why Supplementation Matters Around HIIT?
A single HIIT class can:
- Spike your heart rate to 85–95% of its max
- Burn through muscle glycogen
- Create microscopic muscle damage (which needs repair)
-
Lead to dehydration and electrolyte loss
That’s why proper nutrition and supplementation before and after your workout isn't optional, it’s the difference between burning out and building up.
What to Take Before a HIIT Class?
Before your class, you want to prime your body for performance without heavy digestion or energy crashes.
1. Creatine for Strength and Energy
Creatine increases your body’s production of ATP (your energy currency). This helps fuel short bursts of high-intensity effort like sprint intervals, kettlebell swings, or burpees.
- Boosts explosive strength
- Supports faster muscle contractions
-
Enhances endurance in short intervals
Best time: 30–60 minutes pre-workout
Dose: 3–5g of creatine monohydrate
Harlo includes a clean 3g dose ideal for women and men looking to lift, sprint, and push hard without bloating or stimulants.
2. Electrolytes for Hydration and Focus
Sweating during HIIT depletes your body of key minerals like sodium, potassium, and magnesium. Without them, you risk:
- Cramping
- Dizziness
- Muscle fatigue
-
Poor concentration
Starting class already hydrated but with a zero-sugar electrolyte drink you stay focused, fueled, and light on your feet.
3. Light Carbohydrates (Optional)
If you’re doing a long or fasted HIIT session, a small snack like a banana or rice cake can help top off energy levels. But if you’re pressed for time or prefer training light, electrolytes + creatine alone are often enough.
What to Take After a HIIT Class?
Post-HIIT, your body is in repair mode. You’ve depleted energy, torn muscle fibers, and lost fluids and now you need to rebuild, rehydrate, and restore.
1. Collagen for Joint and Muscle Repair
While whey protein gets all the attention, collagen is a better fit for HIIT-style movement which puts stress on:
- Joints
- Tendons
- Ligaments
-
Connective tissue
Harlo provides 10g of grass-fed collagen peptides, which help reduce soreness, improve joint recovery, and support elasticity making your next class feel smoother.
2. Electrolytes for Rehydration and Cramp Prevention
Even a 30-minute class can result in a pound or more of water loss, especially if you’re training in heat. Replacing lost fluids and electrolytes is crucial to prevent:
- Headaches
- Fatigue
- Muscle cramps
-
Post-workout brain fog
Harlo’s full-spectrum electrolyte profile (sodium, magnesium, potassium) gets you back in balance without added sugar or artificial junk.
3. Creatine (Again)
Creatine is effective before or after a workout and consistent daily intake is what matters most. Taking it post-HIIT can help:
- Replenish ATP
- Improve muscle hydration
-
Speed up performance recovery
4. Carbs + Protein (Optional)
If you haven’t eaten yet post-class, pair your Harlo with a small carb and protein source like a smoothie, Greek yogurt with berries, or rice and eggs.
But even on busy mornings, Harlo alone provides:
- Hydration
- Recovery support
-
Strength nutrients
All in one fast-mixing, travel-friendly scoop.

Why This Stack Works Better Than Stimulants?
Many HIIT-goers reach for caffeinated pre-workouts or sugary sports drinks but those can lead to crashes, jitters, and gut upset.
Harlo keeps it clean:
- No caffeine
- No sugar
- No artificial colors or flavors
-
Just real performance nutrition your body can absorb
Who Benefits Most from Pre/Post HIIT Supplementation?
This routine is perfect for:
- Busy professionals doing early morning HIIT
- Runners and cyclists cross-training with circuits
- Women focused on tone, recovery, and strength
-
Anyone who wants to recover smarter, not harder
Whether you’re working out 3x/week or daily, a consistent intake of collagen, creatine, and electrolytes helps you progress faster and stay injury-free.
FAQs
1. Can I take Harlo both before and after a HIIT class?
Yes, you can take Harlo twice daily. It’s safe and effective before workouts for hydration and energy, and after for recovery and joint support.
2. Is Harlo better than a pre-workout?
Harlo doesn’t contain caffeine, so it’s better for clean, stimulant-free energy. Its combo of electrolytes and creatine supports endurance without a crash.
3. Do I need extra protein after HIIT?
If you haven’t eaten a meal, a protein-rich snack post-class is helpful. Harlo’s collagen adds support for connective tissue but isn’t a complete protein.
4. What if I do HIIT fasted in the morning?
Taking Harlo before class gives you hydration, energy, and performance nutrients without breaking your fast or spiking blood sugar.
5. Does this stack help reduce soreness?
Yes. Collagen and creatine both help repair muscle and tissue damage from intense exercise, reducing soreness and supporting faster recovery.
