“A boot-camp class that combines upper- and lower-body moves - like walking lunge…” — David Kirsch

If there's one thing that we need to avoid, all of us - young, old - it's processed, refined sugar. There's nothing good about it.

You need to stick to a workout that fits into your lifestyle, targets your body issues, but also correlates to your objectives, whether you're at home, on vacation, in the office, or on the road.

The point of workouts are no longer to do double 60-minute sessions or go to classes five times a week. You don't want to burn out and beat your body up.

As you get older, you really need to be much more dialed in to the things you eat.
