I'm looking for an android app that allows me to customize the intervals I want to train.
For example, training 3 minutes in maximum or near maximum intensity followed by 3 minutes of recovery time.Then another round of training 2:30 min by 2:30 mins of recovery and so on until 30 secs of training by 30 secs of recovery.
After that, the times will increase upwards to get again to 3 min of maximum intensity by 3 of recovery.
I have reviewed a lot of apps and none of them seem to have this feature? Does anyone have a good suggestion?
