Exercise through the years

If you're in your 20s, you should be building your aerobic capacity. It's at its peak at this time in your life, say the exercise experts at Canyon Ranch. And women in their 20s, especially, should be doing weight-bearing activities that put stress on their bones.

Already making your way through the 30s? You should be making exercise a priority even though life is getting busier. Start strength training, if you haven't already, to maintain bone and muscle mass. The Ranchers don't stop here. Check out what they have to say about those of you in your 40s, 50s, 60s, and beyond.

40s -- It takes more now to keep from gaining weight, so commit to a fitness program and stick with it. Now's the time to have your bone density checked too.

50s -- You might want to see an exercise physiologist to have your balance and agility assessed and to develop an exercise plan to maintain and improve these critical aspects of fitness.

60s-- You're not old enough to slow down just yet. You may be less vigorous about your workouts but you should not be taking time off. Have your posture assessed -- sitting and standing -- and do corrective exercises if necessary. Be sure to maintain your flexibility too.

70s -- Do something physical every day, even if it's just a 30-minute walk. Staying active is vital to your health during these years.

80s -- Keep working on balance and have your gait and strength assessed. Very mild, consistent training can make a huge difference in quality of life.
