Time per workout: 30 minutes
Mix up your routine with agility and balance exercises this week. After a 10-minute warm-up, perform one of the agility moves for about 30 seconds, followed by 90 seconds of walking. Do about five of these two-minute drills (if you’re feeling up to it, add a few more). Finish your workout with a 10-minute brisk walk, gradually slowing to a cooldown at the end.
