Secrets to staying fast after 50

One: Rev up your workout. Add bursts of higher intensity movement for a more efficient fitness session.

Two: Don't forget the weights. Strength training protects muscle mass and joints and boosts power.

Three: Pack in protein. Pass over pretzels for peanut butter to get better training results.

Four: Sleep like it's your job. Muscles need sleep to recover, so if you don't snooze, you'll lose!
