Do I need to warm up before a swimming workout?

Warming up before a workout is always a good idea. Taking 5 to 10 minutes to warm up the muscles you plan to use before starting your workout can help loosen your joints and prime those muscles for exercise, Koleber says. Before swimming, perform a few sets of push-ups and planks on dry land, and then spend a few laps swimming at a slow, easy pace to warm up.

The number of calories youll burn when swimming varies depending on your age, sex, body weight, and the intensity and duration of the exercise. However, as mentioned above, a 150-pound person may burn 216 calories from 30 minutes of general swimming (not vigorous), according to Harvard Medical School. If that same person increases the intensity, the expected calorie burn can jump to 360 calories in 30 minutes.

When youre first starting out, any number of laps youre able to do is a good swimming workout. For those who need concrete numbers, however, four laps of any basic stroke is a good distance to start with, Slabaugh says. (For reference, standard-sized pools tend to be 25 yards long, according to U.S. Masters Swimming.) From there, the number of laps you do will depend on your goals, intensity, fitness level, and how much time you have to exercise.

Swimming is a full-body workout. It works the large muscles in your back (latissimus dorsi and trapezius), chest (pectoralis major), shoulders (deltoids), hips (glutes), legs (quadriceps and hamstrings), and midsection (abdominals), Buckingham says.

Many groups of people, including beginners, kids, older adults, pregnant women, people with chronic conditions, and those with joint pain or injuries, can all potentially benefit from swimming. However, its a good idea to consult with your physician if you have any medical condition or injury that may make exercise and swimming in particular unsafe. In addition, Slabaugh recommends avoiding swimming if youre recovering from surgery, have open wounds, or cant complete the strokes.

A comfortable swimsuit and a pair of goggles may be all you need. However, some people may want to wear a swimming cap to protect their hair from damage from pool chemicals or salt water.

Aside from a swimsuit, goggles, and a swim cap (if you prefer to use one), most other swim gear is optional. However, if youre swimming in a natural body of water, its a good idea to get a safety buoy to increase your visibility and give you something to hang onto if you get tired, Koleber says.

Optional gear includes:

While swimming is low-impact, the repetitive motions can still cause pain and injuries, if youre not careful. The most common swimming-related issues include swimmers shoulder, lower back pain, breaststroke knee, and foot and ankle tendonitis, according to the Hospital for Special Surgery(HSS).The best way to avoid all of these injuries is to use proper swimming technique, build strength in the muscles that support your stroke, include a warm-up and cooldown in every workout, and progress your routine gradually, per the HSS.
