Alright, bodyweight training thread. A few notes:

>Resistance is resistance
While this is true, the effects bodyweight training and weightlifting have on the body are different. In bodyweight training, there is a larger incidence of neuromuscular communication, which leads to more effective use of the involved musculature, which in turn yields lower hypertrophy (hypertrophy is induced by 'destroying' the muscles). This is why if you only want to get big, you should lift weights. That is not to say you can't get big doing bodyweight training, it's just less effective.
For instance, take the simple pushup versus the bench press. In a proper pushup, you're pushing about 60% of your bodyweight. However, ability to do a few proper pushups do not translate completely to the 60% BW bench press and vice-versa. This is because in the pushup, there is a lot more feedback on how the body is moving from your proprioceptive senses. In a bench press, you have only your eyes and touch to determine whether the bar is following a good path. The reason a 60% BW bench does not translate to a pushup is simple; a pushup is a more complex movement, which requires activation of a couple more muscles.

>Squats and Deadlifts
Don't bullshit around. Everyone should do squats and deadlifts. After from pistol squats and glute-ham raises, there is very little bodyweight training for the legs possible, so you're better off doing weights. You could do sprints, but nothing beats squats and deadlifts for lower body training. For upper body, bodyweight training is fine.
