Unleash Your Potential with Our Fitness Classes – Powered by Science

Are you ready to take your fitness to the next level? Our dynamic fitness classes are not just about sweat and repetition – they’re an energizing experience fueled by expert coaching, smart programming, and the right active substances to support your journey. Whether you’re aiming to lose fat, build muscle, or simply boost your energy, we’ve got the right blend of movement and science.

Let’s break down the powerful substances that support your performance, recovery, and results:

1. Caffeine Anhydrous – The Energy Ignitor
Found in many pre-workouts, caffeine anhydrous enhances focus, stamina, and metabolic rate. With a typical dosage of 200–300 mg, this concentrated form of caffeine kicks in within 15–30 minutes. It helps you push through plateaus, crush cardio sessions, and lift heavier. No jitters – just pure drive.

2. L-Citrulline Malate – Endurance Amplifier
This nitric oxide booster improves blood flow, reduces fatigue, and increases muscular endurance. Dosage ranges from 6–8 grams pre-workout. Expect better pumps, enhanced oxygen delivery, and less soreness after high-intensity classes like HIIT or strength circuits.

3. Beta-Alanine – Fatigue Fighter
Feel the tingles? That’s beta-alanine working its magic. At a daily dose of 3.2–6.4 grams, it buffers lactic acid buildup, allowing you to go harder for longer. Perfect for spin, circuit training, or any class where high-intensity intervals dominate.

4. Branched-Chain Amino Acids (BCAAs) – Muscle Protectors
Prevent muscle breakdown and accelerate recovery with BCAAs (Leucine, Isoleucine, Valine in a 2:1:1 ratio). Recommended dosage: 5–10 grams during or after class. They help maintain lean mass during fat loss phases and support muscle repair post-workout.

5. L-Carnitine – The Fat Converter
Want to melt stubborn fat? L-Carnitine helps transport fatty acids into your cells to be burned for energy. Ideal dosage: 1–3 grams daily, especially before cardio-focused classes. Boosts endurance and maximizes fat burn without stimulants.

6. Creatine Monohydrate – Strength & Recovery Enhancer
Build strength, increase power, and reduce recovery time. Creatine is king. Dosage: 5 grams daily. Safe, effective, and backed by science – great for strength training, bootcamp, and power-based classes.
