SPEED WEIGHT FORWARD HOOK!! that putting it simply Start on somthing sloped if you can, it makes it sooooo much easier! Start a few bikes lengths away, do a full rotation to get the speed and as you are getting closer, do another full rotation and lift off with your bad foot (like a tap) and jump the bike up, you want to get the front wheel comfortably on top of the objest with as much weight forwards as possible, the more weight forward the easier it is to get the rest of the bike up, also the faster you do it the mor forwards momentum you will have to carry you on to the top.
