Watching a video demonstration is far easier to understand and follow than reading about it.
There are many fitness and exercise routine DVD's available to buy, many are made by celebrities.
There are also online exercise programs such as :- Insanity ; Cize; Piyo by Beachbody(R) and those by by Les Mills(R). But these can cost almost as much as a gym subscription and more advanced ways of fitness training.
But there are endless fitness routine videos available on the internet (Youtube) that you can watch and use for free, just choose one that suits your needs.
The example videos shown below are not mine, they are just links to those available on the internet. All credit must be given to the individual video makers.
