Swimming is a great way to build muscle, as it involves exercising against water resistance. The main muscle groups involved in swimming are the gluteals (buttocks), which are responsible for the leg actions in all strokes, and the latissimus dorsi (back) which drives the upper arm motions and most of the pulling. The deltoids (shoulders), biceps (front of arms), triceps (back of arms) and pectorals (chest) all assist in the upper body strokes, while the quadriceps (front of thigh), hamstrings (back of thigh) and calves (lower leg) function in all leg motions.

The latissimus dorsi muscle (back) drives the upper arm motions and most of the pulling
The latissimus dorsi muscle is a back muscle that is crucial in all swimming strokes. It drives the upper arm motions and most of the pulling. The stronger your latissimus dorsi muscle, the greater your distance per stroke will be.
The latissimus dorsi muscle is one of the upper back muscles that stabilise the shoulders throughout the swimming strokes. It is also one of the muscles that make up the shoulder muscles.
The latissimus dorsi muscle is particularly important in the butterfly and front crawl strokes, where it ensures balance and provides propulsion.
The muscle is also used in the breaststroke, where it is one of the upper body muscles used, along with the pectoralis major (chest muscles), biceps and triceps (arm muscles), brachialis, brachioradialis, and deltoids (shoulder muscles).

The gluteus maximus is the main driver for hip extension and power propulsion
Swimming is exercise against water resistance, and any form of exercise against an external resistance will build muscle. The main muscle groups involved in swimming are the gluteals (buttocks), which are responsible for the leg actions in all strokes. The gluteus maximus is the largest of the butt muscles and is the main driver for hip extension and power propulsion. The gluteus maximus is the primary mover in hip thrusts, responsible for hip extension and playing a critical role in generating power and strength in the lower body. It is the most powerful muscle in the hip extensor group, responsible for more than 75% of the total power output. The gluteus maximus is also the chief antigravity muscle during sitting, by counteracting and controlling the flexion of the hip. It is also used for functional activities involving upward and forward propulsion of the body, such as jumping, running, and stair climbing.
The gluteus maximus works in conjunction with the semitendinosus and semimembranosus to extend and externally rotate the thigh. It also works synergistically with the iliopsoas, piriformis, and obturator muscles to externally rotate the hip. The gluteus maximus is activated at the beginning of the stance phase and is used to prevent hip flexion.

The pectoralis major (chest muscles) are used in the breaststroke
Swimming is a great way to build muscle, as it involves exercising against water resistance. The muscles used in swimming depend on the stroke being performed. The breaststroke, for example, is a challenging stroke that requires a lot of rhythmic movement from the arms and legs, working a lot of different muscle groups.
The pectoralis major is a thick, fan-shaped or triangular convergent muscle of the human chest. It makes up the bulk of the chest muscles and lies under the breast. The pectoralis major arises from parts of the clavicle and sternum, costal cartilages of the true ribs, and the aponeurosis of the abdominal external oblique muscle. It is used in the breaststroke, along with the biceps and triceps (arm muscles), brachialis, brachioradialis, and deltoids (shoulder muscles). These muscles work together to create the powerful arm movements needed to propel the swimmer forward. The pectoralis major is primarily used during the catch phase to sweep the arms inward against the water.
The breaststroke also uses lower body muscles, including the glutes, quads, and calves. Understanding the function of these muscles during the different phases of the breaststroke (pull, kick, and glide) can help swimmers optimise their technique and performance. Dryland exercises can also be incorporated to strengthen the muscles used in the breaststroke, enhancing overall swimming efficiency.

The calves (lower leg) point the ankles
Swimming is a great way to build muscle, as it involves exercising against water resistance. The muscles used in swimming depend on the stroke you are doing, but there are commonalities between them. For example, the calves (lower leg) point the ankles. This is true for all swimming strokes. The calves are part of a group of leg muscles that help the body move forward in the water by providing additional power and speed. These include the foot muscles, hamstrings, quadriceps, hip flexors and gluteus maximus. The stronger these muscles are, the faster you will be able to swim.

Swimming is exercise against water resistance, and any form of exercise against an external resistance will build muscle.
All swimming strokes give the body's main muscle groups a good workout, but the stronger your latissimus dorsi muscle, the greater your distance per stroke will be.
Breaststroke uses upper body muscles including the latissimus dorsi (back muscles), pectoralis major (chest muscles), biceps and triceps (arm muscles), brachialis, brachioradialis, and deltoids (shoulder muscles).
The front crawl uses the latissimus dorsi muscles to ensure balance and provide propulsion. You must also engage your foot muscles, hamstrings, quadriceps, hip flexors, and gluteus maximus to counterbalance in the water and swim faster.
