Aerobic exercise is activity that noticeably increases your breathing and heart rate for an extended period of time, but doesn’t leave you feeling out of breath. It’s exercise that challenges your heart and lungs.
Aerobic means “with oxygen” and refers to your body using oxygen to make energy. It’s also referred to as cardiovascular exercise (“cardio” for short), or endurance exercise.
Aerobic exercise also involves continuous movement of your large muscle groups: your legs, thighs, butt, back, and/or chest.

The recommended amount of aerobic exercise to lose weight and keep it off is 45-60 minutes a day, 5-7 days a week.
