Muscle tissue is made up of two protein filaments: myosin and actin. These filaments interact to initiate muscle contractions, and over time, the constant movement will damage them. This is why your muscles need a daily supply of protein to repair and rebuild themselves. The harder you train, the more protein you need.

Enzymes in the stomach and small intestine break protein apart to form peptides
The process of protein becoming muscle begins with enzymes in the stomach and small intestine breaking protein apart to form peptides. This is the first step in the process of protein becoming muscle.
Once the protein has been broken down into peptides, these are then further broken down into amino acids. These amino acids are then used by the body to rebuild muscle fibres. The harder you train, the more amino acids your body will need to repair and rebuild muscle.
The amino acids are shipped to the liver, which then sends them to the muscles. Once there, the amino acids are used to create myofibrils, which are bundles of protein filaments. These myofibrils are critical to muscle contraction and help to repair and rebuild muscle fibres.
Muscle tissue is composed of a repeating structure of two protein filaments: myosin and actin. These filaments interact with each other to initiate muscle contractions. Over time, mechanical stress caused by constant movement will damage these protein filaments. As a result, your muscles need a daily supply of protein to rebuild themselves and stay functional.

Muscle tissue is composed of a repeating structure of two protein filaments: myosin and actin
The body uses protein to repair and maintain its tissues, including muscle. This process is called muscle protein synthesis, which strengthens and builds up muscles by adding new muscle fibres in response to external stress experienced during resistance training. The harder you train, the more protein you will need.
Protein is made up of chains of amino acids, which are used by the body as building blocks to rebuild muscle fibres. Your DNA acts as a site foreman, calling up specific amino acids and directing their deployment. Your muscle repair team uses the fresh supply of aminos to weave myofibrils (bundles of protein filaments), which are critical to muscle contraction. The newly made myofibrils fuse with the damaged areas of your muscle fibres, making the muscle bigger and stronger than it was before.

Amino acids are used to rebuild muscle fibres
Muscle tissue is composed of a repeating structure of two protein filaments: myosin and actin. These filaments interact with each other to initiate muscle contractions and, over time, mechanical stress caused by constant movement will damage these protein filaments. As a result, your muscles need a daily supply of protein to rebuild themselves and stay functional.
Protein is used to repair and maintain your body tissues, including muscle. The consumption of protein helps your body to begin the process of muscle protein synthesis, which strengthens and builds up your muscles by adding new muscle fibres in response to external stress experienced during resistance training.

Your DNA acts as a site foreman, calling up specific amino acids
Muscle tissue is composed of a repeating structure of two protein filaments: myosin and actin. These filaments interact with each other to initiate muscle contractions. Constant movement and mechanical stress will damage these protein filaments over time. Therefore, your muscles need a daily supply of protein to rebuild themselves and stay functional.
The harder you train, the more protein you need to repair and build your muscles. Multiple studies have shown that the consumption of protein helps your body to begin the process of muscle protein synthesis, which strengthens and builds up your muscles by adding new muscle fibres in response to external stress experienced during resistance training.

Myofibrils fuse with the damaged areas of your muscle fibres, making the muscle bigger and stronger
Muscle tissue is made up of a repeating structure of two protein filaments: myosin and actin. These filaments interact with each other to initiate muscle contractions. Over time, mechanical stress caused by constant movement will damage these protein filaments.
Your muscles need a daily supply of protein to repair and rebuild themselves. Mechanical stress from weight training is strenuous enough to make your muscles bigger and stronger. This is why bodybuilders tend to train with extremely heavy weights.
Protein is used as 'bricks and mortar' by your body to rebuild muscle fibres. The harder you train, the more protein you need. The amino acids in protein are shipped straight to your liver, which then sends them to your muscles.
Your DNA acts as a site foreman, calling up specific amino acids and directing their deployment. Your muscle repair team uses the fresh supply of aminos to weave myofibrils (bundles of protein filaments), which are critical to muscle contraction. The newly made myofibrils fuse with the damaged areas of your muscle fibres, making the muscle bigger and stronger.

Muscle tissue is composed of a repeating structure of two protein filaments: myosin and actin. These filaments interact with each other to initiate muscle contractions. Over time, mechanical stress caused by constant movement will damage these protein filaments. As a result, your muscles need a daily supply of protein to rebuild themselves and stay functional.
The amount of protein you need depends on the type of exercise you're doing. For a split session, 20-25g of protein is needed. For a whole-body workout, take it up to 40g.
