Hollywood actor and sex pot Matthew McConaughey has been pictured running around, cycling, doing crazy yoga routines and more for some time now; but the reason why has finally been revealed.

Matthew is planning on releasing a fitness video for men and has been busy making himself as buff as possible in preparation.

A source told the Sun: �Matt wants to create a lifestyle and fitness video for men. It will be centred on how to get a killer surfers body.

�That�s why he has been working out so much. He couldn�t produce a video giving you promises of an amazing physique if he looked podgy and untoned himself.

�It won�t be a straight workout video but it will advise people on how to enjoy a healthy life everyday - and get a buff body. Lance (Armstrong) is the first of Matt�s celebrity pals he is interviewing for the video to get his hot tips.

�But he is hoping a couple more will get involved to help sell it.�

Now this is all good and well, but when is he going to remove that disgusting, sweaty bandanna??????
