On average, you renew about 1 percent of the cells in your body daily, Dr. Lodge explains.

Those cells come in either stronger (read: younger!)

or weaker (older) than their predecessors did, based on the chemical signals they receive.

Step 1: Move

First things first: you gotta move.

If that meansrunning a marathon, great.

If it’s walking your dog at a brisk pace, that works, too.

Your cells don’t know the difference.

As long as you’re doingaerobic activity, they receive the signal to come back stronger.

To that end, Dr. Lodge urgescardiofor 5 percent of waking hours.

(Quick math: That’s about six hours a week, not including essential warm-up minutes.)

It’s totally doable when you consider that getting your Beyonce moves on at a wedding counts!
