The Tabata Training workout requires 8 intervals of 20 seconds-all-out intensity exercise followed by 10 seconds of rest. Many of you might think how can one do 8 intervals in just 4 minutes? However, according to the research result by Professor Tabata, it is proven the best cardio workout as one can achieve both the aerobic and anaerobic exercises at the same time. Tabata training is a workout with high intensity and high efficiency. Quoted from: http://www.ritsumei.ac.jp/rs/category/tokushu/150715/

Thirty seconds today, a little more tomorrow. Plank takes you from a 0:30 hold to five minutes in thirty days — then keeps going with harder plank shapes instead of ever-longer holds. Every target comes with its reason. Hold it clean and tomorrow moves up. Mark a hold as hard and it repeats. Stop early and the app records what you held and starts from there — stopping honestly is part of the plan, not a failure. - Today: your target in a ring, the line explaining it, and one button to start - The hold: near-black and eyes-off, with a voice coach, haptics, and tap twice to stop - After day 30: five shapes, from long-lever to side plank, each starting lower and climbing again - Record: the 30 days, every day since, and the shape ladder - Streaks that count prescribed rest days, with one earned mend a week for a missed day - Widgets and Live Activity: today's target, your streak, and the hold on your Lock Screen and Dynamic Island - A daily reminder that names your target No account, no tracking, no data collected. Everything stays on your iPhone.
