i really liked THIS
part of the clip you posted Phi.
Funny how the comments are all on about how heavy they are and how his isn't a lightweight floppy one ... but it IS a floppy one, you can see it flex about halfway through the video. Awful. Maybe he canoes.
Back to the OP : Thanks for posting your training thing. Can you do it with the (Jeremy) guy in black not falling down? He could just take a step back instead then you can get more sessions in before he gets tired.
