Walking - A brisk walk around the neighborhood is a great way to get your blood flowing and to enjoy some fresh air!
Biking - Biking is a great cardio workout that is low impact. If you have little ones who can't bike along with you, consider a bike stroller/trailer.
Jogging - If you get out for a jog early enough, you avoid the mid afternoon heat, and you'll get the added bonus of starting your day with fresh air and cardio!
Swimming - Swimming is a great, low impact exercise that makes for some perfect summertime cardio!
Dancing - If you live close by a community center or gym, you likely have access to a Zumba class which is a fun way to burn calories! If you prefer to stay home, turn on some tunes, and have fun jumping around the living room!
