I find an elliptical jogging machine to be far better than a stationary bike or treadmill.....you get a vastly better cardivascular workout and a lot more muscle use without any of the pounding on he joints you get with running or weights.
My own favorite is the Precor EFX 541.........in between weight training days....I do cardio on one of these several times per week...its a great workout and easy on the joints.
From the cradle to the crypt...it's a mighty short trip...So get it while you can!!!
I'm living on "tropical standard time"!!!
Yes I Am a Pirate! 200 years too late....the cannons don't thunder...there's nothing to plunder...I'm an over 40 victim of fate!
