I don’t enjoy most exercise. For me the key to doing less favored exercises is limiting each type of exercise to 30 minutes or less. For example, 30 minutes cardio, 15 minutes strength training, 15 minutes of stretching. Longer might be better, but it’s no good if you’re so turned off that you don’t do it at all.
Having said that, there are some kinds of exercise that I do love. I can go for an hour and a half; I’d keep going if I didn’t have other things to do. These are:
Hula hooping. For beginner instructional videos I recommend Hoopnotica DVDs 1 and 2. Also, do it outdoors if you can.
Water aerobics class. I don’t live near a pool now, but I used to love it.
Some women I know love NIA, but it wasn’t my thing.
