Bodyweight Training

Performing strength training without weights is not only possible, the world of gymnastics shows that fantastic strength and physiques can be built using only your bodyweight. Upper body strength developers like the push up and pull up are obvious choices as are squats, lunges and step ups for the lower body.

This Everything Push-Ups article from T-Nation has some great ideas and routines for push ups.

Pull up progression is covered in this Clear the bar article from Experience Life mag.

Beastskills has a range of tutorials that cover the entire body and includes a few different combo moves as well.

Putting everything into a routine is covered by Bodyweight Culture which has a series of 20 challenges to progress through. (Please note: you must register first to be able to view the challenges)

The equipment required for bodyweight training is minimal and in some cases non-existent, so don't let not having access to weights stand in the way of your strength progress.
