well if u havhnt already tried this u can do truckdrivers with straight legs or bent legs so try the one u havnt unless uve tried both, do u mean u cant do it with a spin or even staright air trucks u cant do
riding up the lift lift ur ski up and grab both skis like a truck driver and hold it for a while and now riding up i can just lift up my skis and pull my skis back with out even trying and that made truckdrivers easier
i have the same problem too....although i am very flexible becuase i can put my fists to the ground with straight legs but i just cant ever seem to lean forward enough with my uppper body
