I had the pleasure of seeing the Drowsy Chaperone in Los Angeles before it headed to Broadway and then once again upon its return. It is one of my favorite original musicals containing all of the fun of 42nd Street in a new story about The Man in the Chair with an acerbic view of musicals in the modern day compared to the silliness found in the old 20's and 30's musicals.
Machine weights also can be effective weight training tools, as long as you use machines that adjust to your body dimensions and allow your joints to move through their natural motion paths. Machine weights are generally safe when used with the proper technique.
The key to getting a good workout on an elliptical machine is by using your arms properly during the exercise. Stand straight rather than tilting forward to get the most benefit in your lower body. Free weights are another common and effective type of home exercise equipment. With a weight bench, a set of dumbbells and a barbell with weight plates, you can exercise every muscle in the body. Exercise balls and medicine balls also offer a whole body workout, and this exercise is very gentle on your joints and back.
