What You'll Learn
Strength training
There are several ways to approach strength training. One method is to use your body weight or work against resistance. This can be done using weights, resistance bands or even your own body weight, as in push-ups or pull-ups. When using weights, it's important to warm up before attempting to lift heavy loads.
The number of repetitions and sets you perform will depend on your goals and current strength level. A typical training session could take less than 20 minutes, with 8 to 12 repetitions of each exercise performed as 2 or 3 sets. For power training, you might perform 4 to 10 repetitions of 1 to 3 sets, with longer rest periods of 3 or more minutes. For optimal strength training, you might perform 1 to 8 repetitions of 3 to 6 sets, resting for 1 to 3 minutes between sets, using a load of 80% or greater of your 1 RM.
Consistency is key when it comes to building strength. It is recommended to perform muscle-strengthening exercises at least twice a week, allowing for rest days in between to give your muscles time to recover. It is important to get enough sleep, as this is when your muscles recover and your body grows. A balanced diet is also important, providing the energy your body needs to rebuild and grow muscle.

Nutrition and protein consumption
The recommended dietary allowance (RDA) for protein is 0.8 grams of protein per kilogram of body weight. This amount is based on the minimum required to prevent lean body mass loss and maintain nitrogen balance. However, research suggests that higher protein intakes, ranging from 0.5 to 3.5 grams per kilogram of body weight, can support increases in lean body mass and strength when combined with resistance training. It is important to note that consuming more protein than the body needs can lead to decreased muscle mass, as the body will break down muscle to obtain the amino acids needed for other functions.
To effectively build muscle mass, it is crucial to ensure adequate calorie intake and a balanced diet that includes high-quality carbohydrates and dietary fat. Carbohydrates provide the fuel for working muscles, and without them, the body may use protein as an energy source. Timing of protein intake is also important, with muscle protein synthesis stimulated by both strength training and protein consumption. Spreading protein intake evenly throughout the day and having a bedtime snack containing protein can help maximise muscle growth.
While animal proteins are a common source of protein, it is not necessary to rely solely on them. Vegetarians and vegans can also consume enough protein to support muscle development with careful planning and attention to total intake. It is recommended to include a variety of protein sources to allow for a prolonged release of amino acids into the body. Additionally, regular meals with protein sources throughout the day are generally sufficient for muscle growth, and there is no need to eat immediately after exercising.

Recovery and sleep
Sleep is integral to the muscle recovery process. During sleep, the body undergoes several physiological changes that aid in the repair and recovery of damaged tissues. These changes are necessary for muscle recovery, especially after a workout or an injury. Sleep helps regulate hormone levels that are important for muscle recovery. Testosterone, a hormone that promotes muscle growth and repair, is primarily released during sleep. A lack of sleep can disrupt testosterone production, negatively impacting muscle recovery.
Additionally, sleep helps the body replenish its muscle fuel source, glycogen, which gets depleted during exercise. Sleep deprivation can lower your body's sensitivity to insulin, hindering the replacement of glycogen. Sleep is also important for regulating protein synthesis, especially the synthesis of myofibrillar proteins, which are fundamental to muscle growth. Sleep deprivation can lead to a decrease in protein synthesis and an increase in protein breakdown, resulting in a net loss of muscle mass over time.
The amount and quality of sleep directly impact the body's recovery process. Aim for 7-9 hours of sleep each night, but keep in mind that your personal sleep needs may vary based on your lifestyle and training regimen. During the REM sleep phase, your body focuses on re-energizing your mind, while the NREM phase, specifically the deep sleep stage, is when the body's physically restorative processes occur. During this deep sleep stage, the pituitary gland secretes about 70% of its human growth hormone (HGH), which stimulates tissue growth and helps repair muscles.

Hormone activation
Developing muscle requires a healthy hormone system, which is essential for people trying to gain muscle. During and after a workout, the body releases different hormones, which are either anabolic or catabolic. Anabolic hormones enable muscles to grow through a process known as anabolism, where energy is used to construct molecules. Catabolic hormones, on the other hand, break down molecules to release energy, thereby inhibiting muscle growth.
To develop muscle, you need more anabolic hormones than catabolic hormones. Testosterone, human growth hormone, and insulin-like growth factor play a role in muscle growth and repair. Testosterone, which is primarily produced in the testes in men and the adrenal glands and ovaries in women, has a significant impact on human physiology, including tissue growth. It binds to testosterone-specific receptors on the muscle's membrane. Human growth hormone (GH) travels through the bloodstream and stimulates the production of insulin-like growth factor-1 (IGF-1) in the liver and muscles. IGF-1 then binds to a receptor on the outer membrane of the muscle fibre and signals the muscle cell nucleus to increase protein production.
Resistance exercise naturally increases the concentration of anabolic hormones in the blood during exercise and for about an hour afterward. This helps signal the body to rebuild and repair body tissue, including muscle. The hormonal response to exercise is greatest when using high-volume exercises with heavy loads, short rest periods, and exercises that target large muscle groups, such as squats, deadlifts, and power cleans. However, it is important not to overdo it, as long-term elevations in cortisol, a catabolic hormone, can promote muscle loss.
To stimulate anabolic hormones, you can try weight training and HIIT cardio workouts. Diet also plays a role in hormone activation; eating fewer carbs can increase growth hormone, while eating carbs before or during a workout can minimise cortisol levels. Fasting, when done safely, can increase GH levels, and consuming protein after a workout can keep testosterone levels high.

Resistance training
To build muscle through resistance training, it is important to understand the principle of progressive overload. This means that to gain muscle, resistance training activities need to be challenging for your muscles, and as your muscles adapt, you should increase the intensity of your training. For example, you could adjust the weight, reps, sets, rest time, or range of movement. A good rule of thumb is to rest the muscle group for at least 48 hours to allow for muscle repair and growth.
When starting a resistance training program, it is recommended to begin with a few basic exercises and gradually increase the number of exercises, sets, and reps over time. A typical beginner's strength training program involves eight to ten exercises that work the major muscle groups of the body, performed two to three times per week. Each exercise should start with one set of eight repetitions, no more than twice a week, and gradually increase to two to three sets of eight to 12 reps every second or third day. As you become more experienced, you can section off certain body parts or motion types to focus on during each training session.
There are many exercises that can be performed with resistance bands, such as bicep curls, chest presses, and standing rows. Dumbbells and kettlebells are also effective tools for resistance training, allowing for a variety of ranges of motion and movements. For example, you can try a full-body dumbbell exercise where you hinge at the hips with a flat back, row the dumbbells towards your torso, and then return to the starting position.
