Welcome. Glad to have you join us. Sure salt is allowed, but as I am sure you are aware most of us eat far too much salt as it is so don't go nutty. ( I am a very BAD salt addict, but luckily my BP has tolerated it so far)
I workout before work from 4:30-5:45 and it's lucky i can even get my eyes open then, so driving to a gym isn't an option for me. I rely on videos - aerobics, step aerobics and free weights.
www.collagevideo.com is a great resource to read reviews and even see short clips of workouts.
I don't know your workout level, so I can't really recommend anything.. just that we all need to exercise on a regular basis!
