M3W4D1. Completed. 4 more days and JR&D 90 day workout COMPLETED.
I downloaded the YoaYoa jump rope counter app. You get 1 free day trial and seems to work so signed up for 7 day free trial.
Using my Apple Watch and IPhone the app works great. When you start app on watch to count wrist turns the iPhone screen starts so you can watch you count/tume/heart rate.
Of course it syncs with Apple Health. Put on some music in earbuds and get to it.
I started last week doing 1,000 skips before starting JR&D workout, continue using the app to count skips in workout and then after workout skip until I hit 4,000. Really ads to the JE&D workout.
