And by "TUT," we are not referring to good old King Tutankhaman, nor the dance moves that are named after him, but in this instance, it stands for "Time Under Tension." When it comes to calisthenics, in order to build muscle, it's not about how many reps you can bang out in a row, nor the amount of weight pushed or pressed, but rather, as the name suggests, how much time you put your muscles under pressure, or tension.
See how the gymnasts do long sets on the rings, parallel bars, and pommel horse? That is what is referred to as time under tension, and is the very thing that allows them to create such massive musculature. Doing a 100+ push ups every day, while an impressive feat in its own right, will not give you that long sought after shredded physique. As a matter of fact, despite the fact that your strength and endurance may have gone through the roof, your body may not look much different at all.
As demonstrated by the gymnasts, time under tension is accomplished by performing long, drawn out, continuous sets with multiple movements. For example, on the bars, you can start with muscle ups, then move onto front levers, back levers, ice cream makers, pull ups, etc. all back-to-back, nonstop. Basically, you just keep going until you get gassed. The same can be done on the floor, with varying positions of push ups, handstands, planche (or planche progressions), etc. Just remember to do each rep in a slow and controlled motion. The idea is not to do as many as you can, as fast as you can, but to be able to feel the tension on your muscles for the entire duration.

Happy training!
