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.
Another common form of resistance training equipment is weight machines. This form of weight training equipment can provide the same high levels of weight that free weights provide, and it tends to help athletes maintain proper form during the different lifts.
