I'm a 68-year-old woman who has been involved for almost 6 years in regular exercise classes at my local YMCA--weight lifting, yoga, and zumba. I also get on the treadmill once a week and do 5k. In the weightlifting classes, I use 5-pound, 8-pound, and even 10-pound handweights and load 16 pounds on the barbell. I find that I'm able to do all the exercises without any adaptations. Is there anyone else out there my age who has a similar exercise routine? So many of the senior-fitness programs focus on watered-down, "safe" exercises. I maintain that seniors are capable of much more.
