This chap in the video is obviously exceptionally strong and trained for a very long time.
Use this video as inspiration to see what can be achieved with a very simple exercise. Pull Up bars or monkey bars are in most gyms or health centres, but are usually only used by more advanced trainers.
Don't be afraid to ask advise or to use exercise bands to help you complete a repetition, if you stick with this exercise the rewards will come. Start small and build up your routine allowing 48 hours rest between sets to allow your muscles to rebuild and recover.
Stick with it.......
