is this sentence correct?

[seaswan]

hi,
I do hula hoop every day and I do ropewalking twice a week and do pull up once a week.

[Tukanja]

Ropewalking could be stepping up over the rotating rope which two ends one keeps in his hands. He moves his hands by way of moving its joints forward and forward in a circle.
The rope makes a half of an ellipse and its middle is going in a circle from over his head down to earth and up again, and again.

But what could be pull up?
