desantisfitness: What doesn't kill you makes you stronger, right? 😁😁 My shoulders were on fire within the first 30 seconds! 🚒🚒🚒🚒🚒🚒🚒 I hate 😡 that feeling and love ❤️ it at the same time. I know it's working but man it hurts! Haha!! Day 6 done and I'm looking forward to Yoga Fix Extreme and teaching a live PiYo class tomorrow.....although my shoulders may not be happy! 😡😡😂😂 #21dfx #shoulders #workoutathome
