1️⃣ “The only thing that matters is putting more weight on the bar.”

✅ Fact: Progressive overload isn't just about increasing weight. You can also progress with volume, density, or technique.

  • ⏱️ Density: Reduce rest periods (e.g., from 2 min to 60 s) and increase metabolic stress.
  • 📉 Drop sets: Reach failure, then drop the load by 20%, then continue. 🔥 Ideal for Bulgarian squats or bench presses.
  • Technique and tempo: Lengthen the eccentric phase (3–4 s) and increase the time under tension without touching the kilos.

💪 Practical tip: For legs, try this:
✔️ 3x8 with your usual weight + 90s rest
✔️ 1x12 drop-set to failure (−20%)


2️⃣ “Vitamins are taken for 3 months and then discontinued.”

✅ Fact: Micronutrients are used every day, not in cycles.

  • 🧬 Functions: They aid in repair, metabolism, and oxygen transport. Your body needs them every day!
  • 💊 Multivitamin: Works as a daily insurance, not a “phase” supplement.
  • 🥬 Natural sources: Spinach, tomato, peppers, and legumes are key (and local!).

🥣 Practical tip: Oatmeal + yogurt + berries + nuts = a natural combo of vitamins and healthy fats 🧠


3️⃣ “You won’t grow without training 6 days a week.”

✅ Reality: Less is more with structure and recovery.

  • 🧱 Effective frequency: 3–4 well-structured sessions (push/pull/legs/full-body).
  • 🎯 Autoregulation: Use RPE or RIR to adapt your effort to your energy level.
  • 😴 Rest: Deep sleep activates anabolic hormones. Overtraining slows you down.

📅 Practical tip: Example week:
🟢 Monday: Push (chest, shoulders)
🟢 Wednesday: Pull (back, biceps)
🟢 Friday: legs + core
🟡 Saturday: light full-body or optional cardio


4️⃣ “Cardio ruins your strength gains”

✅ Fact: When timed right, cardio speeds up your recovery and improves your overall health.

  • 🚶 Post-workout: 20 minutes at a low pace = more blood flow + less lactate.
  • HIIT: Do it on separate days from strength training.
  • 🌞 Extra bonus: Biking or walking outdoors gives you vitamin D and breaks your mental routine.

👣 Practical tip: After your workout, walk for 20 minutes outdoors: in the park, on the coast, or wherever you have nearby.


5️⃣ “More protein = more muscle”

✅ Fact: There is an optimal range (1.6–2.2 g/kg) that favors synthesis without unnecessary excesses.

  • 🔁 Too much protein: It can crowd out other key macros and overload your kidneys.
  • 🐟 Varied sources: Fresh cheese, legumes, fish, eggs… nutritional balance.
  • ⏱️ Distribution: 4–5 doses per day to get the most out of it.

📏 Practical tip: If you weigh 70 kg, aim for 110–150 g well distributed daily.

📚 Frequently Asked Questions (FAQ)

🤔 Can I combine RPE with drop-sets? Yes, of course. When you reach RPE 8, you can add a drop set to prolong the muscle stimulation without breaking your technique.
💸 Where to buy quality protein at a good price? MyProtein, HSN Store, or pharmacies with premium brands. Always check the label and make sure it has a good amino acid profile.
🔄 How often should I check my macros? Every 4–6 weeks. If you notice a plateau, adjust by 10% up or down based on your goal.
