@santacruzmedicinals: This was actually a brutal ab workout 3 rounds of…. 20 knee tucks 15 elbow to knee bicycles each side 20 heel taps 15 sus ups 😂 20 feet up toe touches The challenge is how many toe touches you can get in 45 seconds! Comment below how many you can get! I tried it after the rounds of the ab workout and it was brutal. My abs are legit sore today! #santacruzmedicinals #workoutchallenge #abworkoutathome
