Build Muscle

Fuel your body to train harder, recover better, and grow stronger.

How to support muscle growth

Focus on habits that help you train hard, fuel progress and recover well enough to keep building.

1

Train progressively

Give your muscles a reason to grow by gradually increasing weight, reps, control or total training volume over time.

2

Prioritise protein

Protein supports muscle growth and maintenance, especially when paired with regular resistance training.

3

Eat enough calories

Muscle gain needs energy. Fuel your training with enough food to support strength, size and consistent progress.

4

Recover consistently

Sleep, rest days and smart recovery habits help your body adapt between sessions, so you can keep training hard.
