One of the most important things about committing oneself to exercising is dedication. So many people skip a workout or two and give up completely.
Don't be one of those people.
Sure, I hurt my foot and needed to give it a rest. But five days later, I jumped right back into my workout, the foot much better and my muscles no weaker than they were when last I used them.
Truth be told, I did arm exercises while my foot healed. And that's another thing to consider. Even if you have an injury, you can work on an uninjured body part.
Anyhow, so I did 30 minutes on the elliptical, went through all my usual machine weight exercises, incorporating the newly discovered conductive row and being careful to avoid back injury this time. Then I used the Precor (thanks, Darryl, for pointing out the name of the machine I've been using), stretched, and called it a day. Approximately 800 calories burned.
I'm back, baby.
