5 Reasons Your Pre-Workout Isn’t Working - And How to Fix It

by Iron Body Nutrition & Supplements

Are you taking a pre-workout and still feeling flat in the gym? You're not alone. Pre-workouts can be game-changing, but only if you're using the right product, at the right time, in the right way.

At Iron Body Nutrition & Supplements, we help thousands of Aussies get the most out of their training stacks. So let’s break down why your pre-workout might not be doing its job and how to fix it.

1. You’re Under-Dosing (Or Using a Weak Formula)

Not all pre-workouts are created equal. If your scoop only delivers 100mg of caffeine and barely any active ingredients like citrulline, beta-alanine, or tyrosine you’re not fuelling much at all.

FIX IT:
Upgrade to a clinical-dosed formula. At Iron Body, we stock heavy-hitters like:

• Boss Nutrition Vengeance
• Zombie Labs Cross-Eyed
• Inspired DVST8
These aren’t beginner blends. They’re stacked for energy, focus, and power.

2. You’re Taking It Too Close (or Too Far) From Your Workout

Timing matters. Take it too early, and the effects wear off before you lift. Take it too late, and it hasn’t kicked in yet when you’re warming up.

FIX IT:
Take your pre-workout 20–30 minutes before you train and always on an empty stomach for faster absorption. If you're training fasted, this timing is even more critical.

3. You’re Dehydrated (Even Slightly)

Caffeine + stim-heavy blends = increased water loss. Even mild dehydration can kill your pump, zap endurance, and leave you flat.

FIX IT:
Hydrate properly. Add electrolytes like EAA+BCAA hydration formulas from Rule 1, Ghost, or Primabolics. Better hydration = better pumps.

4. Your Diet is Holding You Back

No supplement can outwork poor nutrition. If you’re under-eating, low on carbs, or constantly skipping meals, your body won’t have the fuel to train properly even if your pre-workout is solid.

FIX IT: Support your training with smart nutrition and high-quality protein. Iron Body stocks the best in Australia from Dymatize ISO100 to Inspired Whey. Make sure you're hitting your macros and using post-workout fuel to recover.

5. You’ve Built Up a Tolerance

If you’re smashing high-stim pre’s 6 days a week, your body adapts. You’ll eventually feel less energy, focus, and drive from the same dose.

FIX IT:
Take a stimulant break every 6–8 weeks. Try a non-stim pump formula like EHP Labs PSI or Rule 1 Pump and cycle your caffeine. Trust us you’ll feel the difference when you return.

Final Thoughts

The right pre-workout can change your training game but only if you’re using it correctly. At Iron Body Nutrition & Supplements, we test every product on real athletes, real lifters, and real gym floors.

Dymatize ISO100 vs Rule 1 Whey: Which Is Best?

by Iron Body Nutrition & Supplements

When it comes to protein, not all whey is created equal especially when you're training hard and want fast recovery, lean muscle, and great flavour. Two of the most popular protein powders in Australia right now are Dymatize ISO100 and Rule 1 Whey Isolate. Both are premium options, but they serve slightly different goals.

Dymatize ISO100 – Hydrolyzed Whey Protein Isolate

What it is: Dymatize ISO100 is a hydrolyzed whey protein isolate, meaning it’s already partially broken down for rapid absorption and digestion. It’s ultra-low in carbs, fats, and sugars and extremely high in fast-acting protein.

Key Benefits:

• 25g protein per scoop
• 120 calories
• <1g sugar and fat
• Gluten-free
• Fastest digesting protein on the market
• Ideal for post-workout, fasted training, and fat-loss diets

Rule 1 Whey Blend – Isolate/Digestive Matrix

What it is: Rule 1 Whey is a whey isolate and hydrolysate blend that offers ultra-clean nutrition, but with a slightly slower digestion rate than ISO100 — making it versatile for post-workout and as a meal bridge.

Key Benefits:

• 25g protein
• 130–140 calories
• Low sugar (1g or less)
• Added BCAAs and glutamine
• Smooth texture and very easy to mix
• Great value for a premium-grade protein

Either way, you’re getting premium quality, zero filler, and backed-by-science formulas trusted by bodybuilders, athletes, and everyday lifters alike.
