woah, this type of thing i dunno how to explain but i can swing
above 90 deg from the ground (but with a death grip)
when u are the high point backwards, u have to tighten ur body and
push the weight down, legs together, straight in front, then relax
but move your body a bit forward when u are up in front, bend legs,
then relax again while swinging backwards...... then at the highest
point, tighten and push weight down again
have fun and hold tight!!!
90 deg.....
did your childhood revolves around the
swing until u perfect it?
