10 minutes IS enough. Will it train you for a marathon or help you to look like Jennifer Anniston? Probably not. But a 10 minute workout will help you to feel better. Will help you to burn a few extra calories. Will help you to stay in shape for anything life throws at you.
So, if you only have 10 minutes, or even 5, still jump on the treadmill. Or walk around the block. Or check out my awesome 10 Minute Workout.
Make every minute count!
