I put in a bit of deadhanging after tonight's Lau Gar session. I was warmed up from the sparring and so went straight in to the fingerwork:
1) Open Handed Hang (7s x 3s x 1m10s)
2) Closed Crimp Hang (7s x 3s x 1m10s)
3) Half Crimp Hang (7s x 3s x 1m10s)
The way this works is 7s under tension, then three seconds rest - repeated seven times. All this was done on a sturdy door frame in between cooking and watching TV. (Classic isometric training).
The hangs were two-handed and I assisted as necessary. I rested about 5 minutes between each grip type.
