Great video!

Who needs to lift weights??  Everyone as they age!  About 3 years ago, I was doing a lot of Zumba.  I hurt my knee.  The reason why? Doing so much Zumba was causing me to lose muscle in my legs.

I now do 2-3 strength building exercise classes a week.  My goal for the coming year is 3-4 strength building classes a week.  I don't love the strength building the way I love cardio, but to keep me strong enough to do all the cardio I want to do, I hit the weights.
