Which of the following is a recommended exercise modality for pregnant women?

Low impact cardio is a recommended exercise modality for pregnant women because it is safe and effective in promoting cardiovascular fitness without putting excessive stress on the joints. During pregnancy, the body undergoes significant changes, and low impact activities allow for sustained movement that minimizes the risk of injury while still providing benefits such as improved endurance, mood enhancement, and overall health maintenance.

Engaging in low impact cardio helps pregnant women maintain a healthy weight, regulate blood circulation, and prepare the body for labor. These forms of exercise can include activities such as walking, swimming, or stationary cycling, which support adaptability to the body’s changing biomechanics and avoid high-impact stress that could lead to discomfort or injury.

In contrast, high impact aerobics can pose risks due to the increased likelihood of falls and excessive strain on joints, supine weight training might not be advised after the first trimester due to potential effects on circulation and blood flow, and circuit training often combines various exercise modalities that might not accommodate individual fitness levels or specific pregnancy considerations.
