My solution was a free weights class at a local gym. You're with a group of people of all different ages and levels of fitness. For 45 minutes, twice a week (10-11am Tues/Thurs), I've gotten the most bang for my buck ever. It's hard to start, of course. When I started 5 years ago after the birth of my second son, I couldn't even use weights for many of the exercises, and could only tolerate the weight of my own arms! Now, 5 years later, I'm using 10 lb. weights for shoulders, 20 lbs for biceps. Stick with it for about 2 months, and it will get easier. I lack the discipline to do it on my own. This class has improved my health - I hardly ever get sick anymore. My arms, and even my back, look better than they ever have, and I'm 42. This is the only exercise I do. 45" twice a week goes so quick and is really such a small investment of time for great returns! Good luck to you. If I can do this anyone can!
