I completed a quick Greasing the Groove ladder tonight. It took about 5 minutes and was based on a ladder of 1234321:
1) Fingertip Pull Ups
2) Tuck Planche
3) Horse Riding Stance
The pull ups started with units of one, the planche in units of 1 second and the HRS in units of 10s. So by set four I completed four FTPUs, a 4s Tuck Planche and a 40s HRS.
I find that the quality of the planche in particular is heavily dependent upon the frame of mind with which I approach the exercise. Some exercises (those I like or am good at), I instinctively approach with the appropriate mental focus. But exercises I find awkward, less so.
Keith is right again!
