Strictly defined, low-impact cardio means at least one foot stays in contact with the ground at all times, but some low-impact activities, like swimming and cycling, don’t involve this movement. Hiking, walking, rollerblading and most step aerobic routines are examples of low-impact sports, as well as swimming. While the intensity of these workouts tends to be lower than high-impact cardio, low-impact aerobic exercise still works your body’s muscles and increases your heart rate, without the additional strain to your joints.

Choose low-impact cardio to start with if you are just beginning your fitness routine. Low-impact sports can also be safer for the elderly or injured. Swimming is an excellent form of low-impact cardio exercise as the water provides a constant resistance to work against while cushioning and protecting your joints against jolts and impacts.

Cycling is also considered a low-impact sport, though it only works the lower body and should be coupled with another form of cardio if you want to target your upper body as well. For other types of medium- to low-impact sports, try cross-country skiing, in-line skating, walking and dancing..to know more clickhere.
