Hi Renee - I'm sorry to hear this, and I hope the calf is feeling better soon. The videos are built to play right on your phone, so something isn't right - email [email protected] and I'll personally get you set up today. And for what it's worth, there's no pulling in our method - you roll up to intensify, so the stretch is always in your control. Ease into it - and if you don't follow the instructions, the results will be different.
