Worth knowing
- Choose a weight that challenges you — not so heavy that form breaks, not so light that the last rep is easy
- HIIT is high-intensity by definition: effort between 7–9/10 during work phases
- Keep rest intervals honest — the short rests are part of the program
- Log the weights used so you can track progress
