I agree with Hakim also.
One thing that can sometimes help with such blockages, is to do a kind of "preemptive strike". By that I mean do more bouncing before doing the Active exercise, including consciously swinging your body while bouncing and also lifting your hands up above your head and letting the hands be loose and just also "bounce" from the wrists.
If you are not bouncing before, start.
If you are, do more: if doing a minute, do three. If three, do five. This can help break up blockages and get the qi moving faster.
