be ccareful to monitor ur feet and the general well being feel of them when using the steeper hills. If ur used to practicin really feeling dorsiflexive movements during ur a skips and high knees while on the flats and very slight inclines, don’t try to do this on the steeper hills. This because the steepness of the hill makes u want to do the skipping and high knee fast, no time to try exaggerate and feel the dorsiflexion. And when doin the skips up the steeper start each drill off with 4or5 smaller grade school skips(for want of a better term) to get momentum and the forced quick proper contact occurring before transitioning to the more aggressive MVP style skips. I think those dudes and dudettes use use a jog run in tfrom the flat before their steep hill to get the momentum going.
