To be fair, any exercise done by this old chap should be encouraged. Apart from his over-developed right wrist and forearm muscles (developed from raising glasses of Chardonnay - not what you first thought) the rest of his once magnificent body (not gay) has been going to seed a bit in recent years.
I'm no longer a shining example of manhood having aslo let myself go to seed. Fortunately, living in a condo has its benefist with an in-house gymnasium (if I can be bothered to use it). When I do use it I usually do a half hour of cardio (bike) and haf hour of free weights and weight machines. The free weights I use are 15kg each (no leotards and leg warmers required). I have to be careful though as since I don't like running I'm in danger of having an Arnie Schwartzenegger upper body and a Pee-Wee Herman lower half.
