Hey Morningstar! I hope your feeling better! Sorry for taking so long to reply! I got the achilles'itis from doing step cardio. It's my only source of cardio as I love it so much, but I was only doing it 3x a week. I think I wasn't using proper form like not planting my whole foot on the step, bouncing too much off the balls of my feet. When I realized what was going on I tried to correct it but that was too late in the game & when it really started to get sore I was doing 2 many workouts with fast foot shuffles in it (Imax 2, Athletic Step) & my all time favorite "crazy shuffle" similar to fast foot shuffle but you fly around the step (Amy's ASC) & you feel like a dance step wizard. BUT it's a killer on the achilles if it's acting up. AND I was in denial! AND I have tendonitis in my inner arms 2! So, I'm out of commission. I'm doing Physio & still doing legs & yoga. I'm trying to be patient & biding my time until I can get back into my Cathe's/Amy's etc, again. I miss them!
