I'm not gonna put the video up simply because it is a crappy quality video at a strange angle that looks even worse on the computer screen. I'll wait until I feel I've got it spot on and film it properly with some of the other stuff I've been training.
Here is me standing next to the wall for comparison. Looking at this photo I'd say the wall is about 11ft. I'm 6 foot 1.
*edit* Oh yeah, I forgot to mention that this wall is called my nemesis because I wanted to get stronger to do this before I progressed any further in parkour. My strength was so lacking that I usually had to use my elbows and knees to get up. The fact I can do reps of this climb up and climp up properly shows the leaps I have made in strength while I've been away from parkour. This wall is what put me off parkour a few years ago so I'm extremely happy that I can easily scale it and it gives me confidence back about other aspects of parkour.
