Hey everybody, unfortunately I'm out of the Summer Shred Challenge for now.

I attempted Week 3 Day 2 and found my Achilles tendinitis flare up. I have to rest my heel from strenuous activity for the time being. It really acted up after Day 1, and I suspect it's due to the 1 minute double unders on top of the other accumulated plyometric exercises we've gone through the past couple of weeks.

My legs and knees do not seem to like to doing DU's for more than 20 seconds at a time, so I'm thinking of substituting other jump rope moves (fast regular bounce and jump rope sprint at max intensity) in workouts with DU's after my heel heals.

Good luck to everyone else doing the challenge.
