Classic Exercise Video Plug
One of my all time favourite execise videos is
Reebok:The Video. This is slightly outdated (1992) because step aerobics is sort of passe, but it still remains my favourite type of work-out.
This work-out is awesome because it is a true step work-out. The rhythm is a slower pace, using a full range of motion to work your muscles as opposed to momentum in some more later dated and sloppier work-out tapes.
The instructor is Gin Miller, who invented step.
No matter how many work-out tapes I get, I always come back to this old classic and always get a decent work-out.
