Fancy equipment:
I am a DI track coach (jumps and throws) and a fanatic about event specific training.
I have CSCS, Level II and Club USAW cert. (big deal….yes for the knowledge)
I train on grass over 70% of the time; concrete slabs for throws; for the indoor season my jumper has had three on tarmat days. He jumped 2.10 his first meet, matching last years best. We work plyo's (much on homemade boxes), throw med balls, drill circles and J's. Low volume and high intensity. It's about the knowledge, athleticism and "want to" to be good.
Many of the best in Europe still rely on substandard equipment. jumpdocg
