Hi Courtney! Do you have any suggestions for a HIIT exercise to replace a few of the lunge/squat options that are easy on the knees? Thank you! Loving this!
Week 5 isolation - Thanks for this challenge - great isolated exercise and HIIT - completed challenge - now lets see if I can better myself 2nd time around
Only up to Day 9.... like so many of the above comments I am really enjoying these short bursts of HIIT. You keep it creative and time just flies. Thanks Courtney!
