When planning an exercise routine, you want to incorporate workouts from each of the three different elements - cardio (aerobic), strength training (anaerobic), and flexibility/stretching. Aerobic exercise builds cardiovascular capacity while anaerobic exercise builds and tones muscles. Flexibility exercises improve the range of motion of muscles and joints.
Aerobic exercises include things like running, walking, biking, swimming, dancing.
Anaerobic exercise involves weight lifting and interval training.
Flexibility examples are pilates, yoga, and t'ai chi.
For cardio, I run, ride a stationary bike, and use a Fat Burning Belly Dance DVD
For strength training, I use Jillian Michaels No More Trouble Zones DVD
and Biggest Loser Power Sculpt DVD
. (And I hope to buy the Kettlebell Goddess DVD
For flexibility, I do the Biggest Loser Weight Loss Yoga DVD
and a Budokon DVD
. (And I'm thinking about trying T'ai Chi also.)
Good luck....and congrats on the engagement!
