Follow me, You can get it. The best waist exercises to shape the perfect body curve. Just workout once and you'll believe it. This sport is specially designed for people who don't have time to exercise. what's ....@#$%^&*.... You read that right, I wrote it right! ! ! This exercise takes advantage of the idea of time overlap so that you don't have to spend extra time working out. We have specially designed abs workouts that can be done at the same time as other things because only the abs need to be exercised. E.g: People who need to take public transport to and from get off work, stand or sit in a car, or even walk when changing cars. People who sit at work in an office can do this exercise while at work. People who like to run can also do this exercise while running. Our workouts are based on yoga, but leave out all body parts. Each contraction and relaxation of the abdominal muscles is called a rhythm. We have designed a series of rhythms to ensure that it does not affect health and achieves the effect of exercise. There is a total of 42 days of exercise cycle, every 7 days is a small cycle, and the rhythm of each small cycle is different. For your health, if you interrupt your workout, start over from day one. According to our tests, someone with a waist circumference of 8x cm can lose 3-6 cm in about 2-3 weeks. People who weigh about 60 kg can lose 1%-2.5% in about 1 month. Our app will help you record your exercise status and waist circumference, and help you measure your waist health with reference to the World Health Organization (WHO) recommendations for a healthy waist. Only by exercising every day can you maintain a healthy waistline and maintain an appropriate weight. We designed this time overlapping exercise APP, hoping that you can maintain the habit of exercising every day without time pressure.

Plainfast is the honest fasting timer. Start a 16:8, 18:6, 20:4 or OMAD fast in one tap and watch a calm dial count the hours. No sign-up quiz, no account, no ads. Open the app and the timer is the first thing you see. You do not answer fifty questions about your body first, and you do not lose your past fasts after a week. Every fast you log stays in your history, free, for as long as you use Plainfast. WHAT IT COVERS ⢠Intermittent fasting with 16:8, 18:6, 20:4 and OMAD presets, plus 24, 36 and 48 hour plans, or a custom target that suits your day ⢠Longer fasts: the clock keeps running past your goal, so 24, 36 and 72 hour fasts are timed hour by hour ⢠Water fasts and extended fasts logged the same way as your daily window ⢠A 10-phase timeline of what typically happens as a fast goes on: glycogen use, the shift toward fat burning, ketosis. Each stage shows how sure the science is and the study behind it, and autophagy is marked plainly as not yet known in people KEY FEATURES ⢠A plain dial that shows time elapsed, time left and your current phase at a glance ⢠Live Activity and Dynamic Island, so your fast keeps time on the lock screen ⢠Home screen widgets ⢠Reminders for the start and end of each fast ⢠Full history, streaks and stats, all free ⢠A note on every fast, written when you end it or later from History ⢠Weight log, plus mood and glucose logs after each fast ⢠Weight sync with Apple Health (Premium) ⢠Export your fasting history as a CSV file ⢠Dark mode that is designed, not just inverted WHO IT IS FOR ⢠Beginners trying 16:8 who want a timer, not a program ⢠OMAD and 20:4 regulars who log every day ⢠Anyone who does an occasional 36 or 72 hour fast ⢠Women and men who would rather track quietly than take a quiz first PRICING Free: the timer, all presets, the phase timeline, full history, streaks, stats, logs, widgets and reminders. Premium (monthly, yearly or a one-time lifetime unlock) adds unlimited custom presets, adding past fasts, mood and glucose correlation charts, and weight sync with Apple Health. Plainfast is a timer and a log, not medical advice. If you are pregnant, diabetic, take medication or plan a fast longer than 24 hours, talk to your doctor first. Payment will be charged to your Apple ID account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period.

On price and in-app purchases there is nothing between them.
