I'm not gonna lie. I am a life long exerciser of all types. I did not try Zumba for the longest time at my gym assuming it was silly and too easy. Finally one night a took a class. NOW I'M SO HOOKED! It's SO fun!!! SO FUN, that even if I cant' motivate to get to the gym and lift weights and use the boring treadmill etc, I can always just "Get there and get into class and have fun" It's the BEST toning and shaping with all the awesome belly dancing and abs stuff for waist along with everything else. I know several moms who lost all their baby weight doing zumba even if they hated exercising in general. I'm amazed at how toned I feel when I do a few classes in a week. I've done it for about a year 2 to 3 times per week to easily keep in shape. If I slack off or put on weight, a good 6 classes in two weeks gets me right back in shape and then some. I'm with Tracy K, instead of feeling like the minutes are endless on the treadmill, you feel like, "Please, just one more song, one more song! Darn, an hour already?"
Take a class, Dawn! They are very cool and "Don't worry about getting it right, just keep moving and have fun". There are all types and fitness levels in there! You would be surprised how quick you catch on.
