Is that suggestion from coach Parrot?
I don't have excel so I have not been able to use it, hence my usual regime is 1v1 to jack up his DR for OD elastics, then train OD. Since OD also gives ID training, and 1v1 increases IS (which I assume would give ID a positive elastic pull), I have always thought that ID could be put off for later. How does my training plan stack up against yours in terms of speed?
