Does Exercise Really Break Down Your Muscles? How They Actually Grow

Here is something surprising: the first thing a workout does is break the muscle down, not build it up. Dr. Amr Elyamany explains how muscle really grows, and the three things you need for it to happen.

What happens when you lift

When you lift weights, the muscle fibres develop very small tears. The body then enters a phase called muscle recovery, in which it repairs those tears. That is when the muscle gets bigger and stronger.

The three essentials

• Protein. Give your body the building material: about 20 to 40 grams of protein after training helps repair and build the muscle.
• Rest. A muscle needs 48 to 72 hours before it is trained again, so do not train the same muscle day after day.
• Sleep. During deep sleep, the body releases growth hormone. Muscles really grow while you sleep, not while you are in the gym.

Which one are you missing?

Ask yourself honestly whether protein, rest or sleep is your weak point, and fix that one first. Training harder will not help if recovery is the missing piece.

Key takeaway: You build muscle in recovery: protein, rest and sleep matter as much as the workout.

When to see a doctor

• Muscle pain that lasts more than a few days after training
• A sudden sharp pain or a pop during a lift
• Persistent tiredness or a drop in performance despite good training
