Terra and Pterrain refers to the environment during Desent or Ptossing, respectively. The types of terra or pterrain are listed below, with Desent terminology appearing first where terminology differences appear.[1]

Types of Terra/Pterrain[]

Types of Pterrain/Terra Description
shelving platforms and ledges
inclines hills and stairs
expanse soft--grass, sand, etc. hard--concrete, asphalt, hard dirt (parking lots)
railage rails, bars, and poles (rails are lower height than you, bars are higher, poles are vertical)
jumpers anything that is used to jump over or that you jump up and touch, and gaps
walls any wall
dtransits/ptransitions anything that you "transit" (crawl under or pass through)
roughage indigenous plantlife (trees, etc.)
weavers things used to "weave" in and out of or for doing agility drills
dtrash/ptrash terra that doesn’t fit into any of the other categories (cars)


Shelving refers to platforms and ledges. A platform is considered to be any flat surface that's higher than the surface on which you stand, but not exceeding your height. It must also be large enough to accommodate exercise. There are any number of things you can do with a platform, and some good examples are box jumps, depth jumps, L-sits along the lip, and of course you can combine box jumps into another exercise: burpee->box jump->burpee on the platform->depth jump. Repeat.

Ledges refer to anything above your height that you can pull yourself onto, which is not a bar. A great example of a ledge is a wall. One of the best exercises for ledges is the plain old mantle shelf, sometimes referred to as a muscle up (not to be confused with top-outs). Other things you can do are handstand pushups, L-sit walks, or balance pushups.[1]


Inclines are hills and stairs. Since the Fifth Law of Ptossing/Desent says you must sprint all hills, these are taken care of. Stairs are easily recognizable also, but they can serve many purposes. Some possible uses for stairs include traditional sprinting, plyo pushups up the stairs, jumping pistols, and handstand walks.[1]


Expanses are pretty much any open area where you would be free to move in excess. There are two types; soft, which is like grass or sand, and hard, which is concrete, asphalt, etc. Think of a parking lot or a lawn. These are excellent for a number of reasons. Anything involving sprinting can obviously be done in an expanse. In addition to this, soft expanse serves as a great place for things like sprawls and low crawling and other QM. Other great exercises for expanses are walking lunges, distance burpees or long jumps, and suicides.[1]


This category consists of cylindrical objects you can grip. These include bars, which are higher than your height, rails, which are not higher than you are, and poles, which are vertical. Railage is excellent for a million exercises. Not only do they allow you to grip better, but sometimes railage is conducive to swinging, which opens up new exercises. For bars: every variation of pullup or leg raise, kickovers, and muscle ups. For rails: every variation of dipping, l-sit walks, etc, as well as precision jumps. Poles can be used for flag raises and climbing.[1]


Jumpers consist of anything that exists (in your ptoss run/dtour) solely for the purpose of jumping. These could be gaps, objects, or things that you use to jump up and touch, such as with touch-ups (basketball backboard, road sign, etc.). Other examples of jumpers include trash cans, park benches, stair rails, possibly cars. An example of a gap would be, as in parkour, the gap created from one rooftop to another, but other gaps might be a drainage ditch or something of lesser elevation. Bear in mind that Parkour vaults do not constitute jumpers, but become a part of whatever you are vaulting, i.e. if you dash vault a rail, the obstacle is considered railage, not a jumper.[1]


A wall is just a wall. Lots of things can be used as walls, and technically, a wall could also be a ledge. Wall runs are good when going into mantle shelves, and walls are also great for handstand pushups and handstand leg lifts.[1]


A dtransit or ptransition is anything you use to "transit" through or under. Examples include low-crawling under something, passing through a hole or a window, or going through a tunnel.[1]


Roughage is defined as "indigenous plant life." It means trees and other plants you can use for exercise. Trees can be used for climbing, pullups, muscle ups, kickovers--things you do on a bar can be done on a tree branch.[1]


These consist of anything you could use to "weave" in and out of or perform any kind of agility drills upon. Things that can be used for this purpose include a series of poles, a row of trees (slolom), etc.[1]


This category is for terra/pterrain that doesn’t fit into any of the other categories (things like cars and oddly-shaped objects and structures that don't really fit the criteria for the other types).[1]
