In terms of training, the clock is useless. In a 25-meter pool, when swimming 16 25-meter segments, there are 22 segments of 50 meters each and give out 1100 meters in 20 minutes. So, at the age of 76, I am sailing for 1 youth! These are the miracles of digitalization. Saturation is measured with an error of about + - 3-4 percent, which is not good. Haven't tried the other workouts. I know my step clearly and have been verified more than once. Google gives the route for the day in meters - I divide by the step size and get the number of steps, which does not beat the clock at all. I knew that something like this would happen, but I really wanted to please myself. Pleased. Fu fu all these lotions, more show-off than the result. If you have nowhere to put your money, buy it, And so one advertisement.
