Jump-rope timer: intervals, a 3-minute set, then stop.
Jump rope is one of the few cardio tools that fits in a drawer and still produces a real heart-rate spike. This timer is built for interval skipping and for a continuous three-minute set — the same time box MiniRep uses as a low-pressure workout habit. Beginners should start with 30 seconds skipping / 30 seconds rest rather than a heroic unbroken five minutes that ends in shin pain and a unused rope. A 30/30 block for 8–10 rounds is 8–10 minutes of clock time and only 4–5 minutes of actual skipping, which is plenty for calves that have not bounced in years. Intermediate skippers can hold a continuous three minutes at a conversational bounce (roughly 100–120 turns per minute for many adults) and treat extra rounds as optional. Fast skipping and double-unders live in a different MET band; the Compendium of Physical Activities commonly lists rope jumping around 8.8–12.3 METs depending on pace (slow/general versus fast or vigorous). Those numbers are population averages, not your watch. A 70 kg adult at 10 MET for 3 minutes is roughly 10 × 3.5 × 70 / 200 × 3 ≈ 37 kcal — a useful magnitude, not a promise. Pace first, calories second. If you want all-out 20/10 × 8, that is the Tabata timer, not this page. If you want arbitrary work/rest, use the HIIT timer. This page stays on rope-shaped presets and the three-minute habit. Educational timing, not a VO2 test, not medical advice. Stop for chest pain, dizziness, or a calf that warns before it tears. MiniRep will not turn the rope for you; it will let you log the three minutes so the habit survives a messy week.
