I am SO a "workout at home" person. The only exercise I do in a public setting is my Middle Eastern dance classes and seminars.
If you would like to start out with hand weights-you can. Some great videos to start with:
"All My Best" by Margaret Richard *my favorite*
( available at
www.bodyelectric.net )
"In Shape With Rachel McLish"
( at about any online video store)
"Getting In Shape With Weights For Dummies"
(at about any online video store)
*I recommend this if you know absolutely nothing about weights...and don't know your bicep from your tricep muscle...because this tells you the info as you go along in layman's terms for someone who doesn't know squat.*
Joyce Vedral has some strength training videos out there that a lot of people like-but I don't like them personally...she goes really fast (to provide cardio at the same time) and I think she displays bad form on some of the exercises. Personally I think her books are better than her videos-because she displays better form showing the exercises-and you can do them at a slower pace.
You can start simple with light 3-5 pound weights, and a kitchen chair with any of these if you are an absolute beginner...but the key is you want to go to heavier weights as soon as the exercises become easier. You should struggle some to do the last couple of each exercise with good form. You don't want to stick with the same weights and just go through the motions...or you won't see much improvement. If you are doing an exercise and those weights are flying through the air while you daydream about something else...you gotta move up.
Check the classifieds for heavier weights and weight benches as you progress to save money.
Personally-I did aerobics and such for years-since I was an early teen-and taking up strength training has been one of the best things I have ever done for my body.
Good luck to you!
