move yourself!
You wont believe how many choices you have to exercise yourself here:1)Hiking, trecking, cycling, There are some easy trails but also some dangerous ones suggested only to experienced ones. The 11 miles of Kalalau trail will top it all as it is located on the Na Pali coast, even if you do the first 2-3 miles you will be reward with some great views.2)canoeing, kayaking, There are specific companies that have licenses to rent and guide kayak tours most of them at Wailua river. They want to protect the river so they keep the daily number at a specific limit.3)surfing, bodyboarding etc You can practice in the calm waters of Poipu if it is your first time 4)Swimming is also a must but watch out which beach you are, the north beaches are better to avoid in winter (the big waves will scare you anyway). Choose some organized ones if you have children, they have lifeguards on duty.
