Excellent training app
I have been using Zing for 2 months now and I don't regret about it. So far, the app has been great and very useful.The training routines are difficult, in a good way. The IA coach is motivating me every day to achieve the goals. There are some things to improve (not very important functions, but I miss them from other apps) like an alarm to remind you when the rest time is due. I'm sure that this app will be with me for the time to come.
