Will Cardio Kill Your Strength Gains?
Short answer… no, not if you do it right. 👇
A lot of people worry that adding cardio to their routine will “cancel out” their strength progress — but when balanced properly, cardio can actually help you build muscle, recover faster, and perform better in your strength sessions.

🧠 The Science Behind It
Strength training and cardio use different energy systems, one builds muscle and power, the other builds endurance and cardiovascular health. The key is timing, type, and intensity.
If you’re smashing high-intensity cardio every day before you lift, your body’s glycogen (fuel) stores and energy will be drained before you even start strength work.
But when done smartly, either on separate days, or after weights, cardio helps:
✅ improve circulation and recovery
✅ increase work capacity (you can lift longer and harder)
✅ boost calorie burn and overall fitness
✅ support heart and lung health

🔑 How to Optimise Both
Here’s how to keep strength and cardio working together, not against each other:
• Prioritise your goal: if muscle growth or strength is your focus, lift first or separate sessions by at least 6–8 hours.
• Choose your cardio wisely: steady-state (like walking, incline treadmill, cycling) complements strength goals better than excessive HIIT.
• Fuel properly: don’t under-eat if you’re adding cardio, recovery depends on calories, protein, and hydration.
• Sleep & recovery matter: 7–9 hours sleep + active recovery = faster progress.
