u dont need a partner for the drills, med balls or pretty cheap that shouldnt be a reason.
why does hills make ur achilles sore. if u really dont like hills use sleds or go 1-2 hill days and 1-2 sleds days. i really like the gpp dvd it was a nice buy for myself. LETS SEE WHAT OTHERS SAY.
keep the lower leg warm, between efforts, do a full warm up and hills are great.
as utfootball says, go the sled if you must, but hills are the go!
keep an eye on the lower leg during the runs, pull out when its getting tight.
surely you could do half the hills?
Med balls are pretty cheap, i found one the other day for 65 aust $$ at 5kg. thats got to be about $5 us?? lol.
i also have no training partner for the med balls, there is soo much you can do by yourself.
I have always wondered about the possibility of hills being sus for athletes at the start of gpp.
would it be better to do accellerations on the flat for a while to adjust to the stresses and then switch to hills and latter back to the flat,or if archilies are in any way sus leave out hills altogether ?
