Resistance training and high-intensity exercise carry inherent physical risks. HeadStrong’s Double Progression targets, Estimated 1-Rep Max (E1RM) calculations, equipment conversions, and Pixel Watch recovery indicators are algorithmic estimates. Always prioritize safe biomechanics, use spotters or safety bars when lifting heavy loads, and stop exercising immediately if you experience pain, dizziness, or shortness of breath.
You retain full ownership of all workout logs, custom exercises, and body metrics entered into HeadStrong. You may export or delete your data at any time from the Program tab.
