If you are trying to build muscle mass, swimming might not be the first sport you think of to help you achieve your goal. Swimming is a good way to build muscle mass in a non-threatening way because it is a non-contact sport that does not put any unnecessary stress on your body. If you are trying to increase your muscle mass, you should learn the benefits of swimming and how it can help you build muscle mass.
Resistance
Water is a natural source of resistance. If you have ever tried walking the length of the pool, you understand the feeling of the natural resistance. It is much harder to march your way across a pool than it is on dry land. This is exactly what your body needs to help it build muscle and is a safe way to build muscle without the risk of pulling or tearing muscles by lifting heavy weights or performing rigorous exercises, such as jogging or cardio exercises.
A Full-Body Workout
Swimming works all the core muscle groups at once. There are few other exercises that can work all your muscles, including arms, legs and abs, at the same time. As an added benefit, there is no strain on your joints or soft tissues as you workout, making it easier to push yourself harder without the risk of serious injury.
Adding Equipment
It is possible to build your muscle mass simply by swimming the various strokes through the length of the pool. You can also increase the muscle mass you gain by adding equipment, such as aqua dumbbells. These are small weights that work with the resistance of the water to increase your workouts. You can also add a jogging belt, which is a piece of equipment that suspends you in the deep water, allowing you to intensify your workout by forcing your legs to keep you afloat.
Choosing swimming as your exercise to help you build muscle mass is a great choice for people of all ages. Experienced and non-experienced swimmers can enjoy the benefits swimming has to offer by building muscle mass in all the core areas of your body. Swimming with or without equipment will help you reach your goals and achieve the muscle mass you desire without putting your body at risk for any harm.

This is a great article, thank you.
I used to swim for many years and it’s definitely a great way to build muscle. Not only that, but you can really make some noticeable changes when you start to add equipment, as mentioned in the article.
I find that swimming is also excellent for helping to recover a back injury. A lot of other exercises are too strenuous on an injured back, or apply too much pressure. Swimming seems to be a fantastic way to exercise and loosen your back without actually over-exerting.
