Sound like a good plan. As far as the med balls no, I’m not using any right now but I do plan on buying a med ball soon. Funny thing is my gym has TONS of med balls but there is nowhere to throw it and I train alone.
As far as the plyo work I just started doing the one leg hops (L-L-L-R-R-R) as outlined in the CFTS last week. Other then that I have never done any other plyo work.
