There are over 600 muscles in the human body, and they all have different functions. Some muscles are cardiac, meaning they help keep you alive, while others are smooth and control involuntary functions, such as constricting blood vessels. Skeletal muscles, which make up about 40% of body weight, are the muscles targeted in strength training. These muscles can be further divided into more specific muscle groups, such as the legs, chest, back, arms, shoulders, and abs. When creating a workout routine, it is important to consider which muscle groups to train together to maximize the benefits of each workout and allow for proper rest.

What You'll Learn
Muscle groups to work out together
When creating a strength training routine, there is no right or wrong way to go about it. However, pairing certain muscle groups together can make your workouts more efficient. For example, you could group muscles based on their location in the body, such as the legs, abs, chest, back, arms, shoulders, and glutes. Alternatively, you can group muscles based on their function, such as the "push" and "pull" muscles. "Push" muscles involve pushing resistance away from the body, such as in a push-up or bench press. "Pull" muscles, on the other hand, involve pulling resistance towards the body, such as in pull-downs.
Additionally, you can also group muscle workouts based on their function as either compound or isolation exercises. Compound exercises, also known as multi-joint exercises (MJE), work several muscle groups at once and include movements such as squats, bench presses, deadlifts, and shoulder presses. Isolation exercises, also known as single-joint exercises (SJE), target specific muscles within a muscle group, such as bicep curls for the bicep muscles.
It is important to consider your body composition, goals, and recovery time when deciding which muscle groups to work out together. For instance, if you resistance train twice a week, you may want to do full-body workouts with MJEs, followed by aerobic activities on your rest days. On the other hand, if you prefer to train more frequently, you can alternate between upper and lower body workouts to give each group adequate rest.
Overall, there are numerous muscle groups that can be worked out together, and the optimal combinations depend on individual factors and preferences.

How to build muscle
Building muscle is a slow process that takes months and years, rather than days and weeks. The human body can change to a limited extent through weight training and increased food intake.
A well-designed weight training program is the best way to build muscle. Training with free weights, like dumbbells, kettlebells, and barbells, is often better for muscle building than machines. However, machines are ideal if you have balancing issues or other limitations that make it safer to sit during weight training.
A complete training program should include a combination of exercises that help improve your strength, flexibility, endurance, and balance. Many exercises will work on at least two different muscle groups together, while others can isolate specific muscles. Compound exercises work several muscle groups at once or require movement in more than one joint to complete a movement. These are called multi-joint exercises (MJE), and include squats, bench press, deadlift, and shoulder press.
When it comes to weight training, you should focus on all major muscles, but there are certain muscle groups that can be trained together. For example, chest, back, legs, arms, shoulders, and abs. Within these groups, you have smaller muscles or muscle groups, such as lats, traps, quadriceps, hamstrings, biceps, and triceps.
The number of days you can make it to the gym, your goals, the types of exercises, and the training styles you enjoy are all factors that will impact your muscle-building plan.

Types of muscle
The human body has over 600 muscles, which help us do everything from moving our bodies to breathing and staying alive. The muscular system is primarily concerned with producing movement through muscle contraction. There are three types of muscle tissue in the human body: skeletal, smooth, and cardiac.
Skeletal muscles are part of the musculoskeletal system, working with bones, tendons, and ligaments to support our weight and move us. These muscles are attached to the bones by tendons and are under our conscious control, meaning we can move them when we want to. They are also known as voluntary muscles. They are grouped into opposing pairs, such as the biceps and triceps on the front and back of the upper arm. Some skeletal muscle fibres contract quickly and use short bursts of energy (fast-twitch muscles), while others move slowly, like back muscles that help with posture.
Smooth muscle is located in various internal structures, including the digestive tract, uterus, blood vessels, gastrointestinal, reproductive, and urinary systems. It is under involuntary control, meaning the motion happens without our conscious awareness. Smooth muscle fibres are located in the walls of hollow visceral organs, appearing spindle-shaped. They are arranged in layered sheets that contract in waves along the length of the structure.
Cardiac muscle, also known as myocardium, makes up the middle layers of the heart and is responsible for the rhythmic contractions of that vital organ. It is the only organ that is also a muscle. Cardiac muscle is under involuntary control and appears striped when viewed under a microscope.

Muscle recovery
To aid muscle recovery, it is important to live a healthy lifestyle, including a nutritious diet and adequate rest. Consuming protein after a workout is beneficial as it helps repair muscle damage. Research suggests consuming 1.6 grams of protein per kilogram of body weight per day is optimal for muscle growth and recovery. Additionally, hydration is key, as dehydration can impair the muscles' ability to repair themselves.
Another way to improve muscle recovery is through massage and foam rolling. Massage helps release muscle tightness, increases blood flow to the area, and promotes the removal of pooled fluid, thus speeding up recovery. Similarly, using a foam roller increases blood flow to the muscles through applied pressure, acting as a form of self-massage.
Furthermore, certain supplements can aid muscle recovery. For example, creatine helps reduce muscle damage and inflammation while replenishing muscle glycogen stores. Additionally, protein powders provide a convenient way to increase protein intake, with some containing essential amino acids.
In conclusion, muscle recovery is a critical aspect of any fitness regimen, and by incorporating healthy habits such as proper nutrition, hydration, rest, and targeted therapies, individuals can effectively support their muscles' healing and performance.

Muscle-building diet
Building muscle requires a combination of weight training, increased calorie intake, and rest days for recovery. A muscle-building diet should be rich in protein, healthy fats, and carbohydrates.
Protein is essential for building muscle mass and repairing damaged cells. Animal sources of protein include lean meats such as turkey breast and beef, as well as dairy products like cottage cheese and eggs. Plant-based proteins such as soy, beans, legumes, rice, peas, and potatoes can also help increase protein intake while providing fibre, which is beneficial for digestive health.
Healthy fats are another important component of a muscle-building diet. Foods like avocado, nuts, and olive oil provide essential fatty acids and calories, which are necessary for energy and muscle growth.
Carbohydrates are crucial for muscle building as they provide the body with fuel for physical activity. Whole grains, such as oatmeal, and legumes, including chickpeas and beans, are excellent sources of complex carbohydrates and also contain protein and fibre.
In addition to these macronutrients, micronutrients like iron and vitamin B12 play a vital role in muscle building. Iron helps store and transport oxygen in the blood and muscles, while vitamin B12 supports nerve health, enabling you to perform the exercises needed to build muscle.
It's important to note that individual dietary needs may vary, and it's always recommended to consult a healthcare professional or a registered dietitian before making any significant changes to your diet.

Frequently asked questions
Muscle groups are collections of muscles that are situated close to one another and work together to perform a specific movement or function.
Examples of muscle groups include the chest, shoulders, triceps, lats, traps, rhomboids, biceps, rear delts, forearms, legs, calves, hamstrings, quadriceps, glutes, and abs.
The muscle groups you work out together depend on several factors, including your body composition, goals, and how many days per week you plan to work out. For example, if you work out twice a week, you should do a full-body workout that targets all muscle groups. If you work out three days a week, you can target different muscle groups each day, such as legs, back, and abdomen on day one, and chest, shoulders, and arms on day two.
