: I love how these workouts in #21DFX are ONLY 30 mins! ⌛️ And they are most definitely challenging! 😳💦😝 I even needed to drop down to my knees and modify the last bit of the push-up round! Oh well, that means I can only improve from here on out & hopefully be able to crush through them all without modifying at the end of this program! 💪🏻 #athomeworkouts #summer2016 #workout
