- 10 Push-ups

Standard vs. Scaled: Choose the movement variation that fits your level for pull-ups, push-ups, and squats. The round structure, rep counts, and 20-minute clock stay the same either way, so results stay comparable.

RND20 is a self-timed bodyweight workout, not a substitute for professional coaching or medical advice. Warm up beforehand, use good form, and choose the scaled variation if you're new to any of the movements. Stop if something feels wrong, and check with a doctor before starting a new exercise program if you have any health concerns.
