Add Heart Rate Variability (HRV)
As a measure of training and lifestyle stress, HRV is a great tool. Such info would allow us to suggest deloads or stress management techniques or at least to investigate possible stresses. There are smartphone apps that measure this so maybe another one to integrate with one of these external apps? HRV4Training is an example of one of these apps.

Yes please. We ask all of our clients to track HRV. I don't love HRV4Training personally, we use EliteHRV. Even the ability to add a custom biometric that they can enter manually would be great.
Ability to measure HRV

Totally agree. Trainerize could utterly differentiate itself as the FIRST fitness app to recognize HRV....get to it guys!!
